Fake SFP and the Third Party SFP

It appears to be an old topic that whether using compatible SFP transceiver is reliable. We have previously discussed this topic couple of days ago. For certain, the reply is affirmative. In this paper we discuss Faked SFP and the Third Party SFP. As examples, there are Cisco SFP module and Brocade SFP module.

It Is A Faked SFP?

Like a break pad an SFP is somewhat a consumable. Light is converted into an electric signal and vice versa, produces heat and the components wear out over time. Some sooner, some later. When you bought the SFPs from Cisco for a switch under Cisco warranty or maintenance, broken SFPs will be substituted for free. However, if you simply decide to purchase an SFP, you will find after having a quick web search that there are lots of supplier out there providing the same SFP for a much cheaper price than Cisco. And with "the same SFP" I mean they provide exactly the same Cisco part number - for example SFP-GE-L . That's an Cisco 1000BASE-LX SFP 1310nm 10km EXT DDM Transceiver Module.

Really The Same SFP?

Absolutely not - even though they claim it to be the same. Their usual explanation is, that all these SFPs are coming from the same manufacturer anyway. SFPs are built using open standards based on T11 and for that reason they must be compatible per se. I can tell from several occasions: That's not true. There is obviously more than one SFP manufacturer and I'm sure each of you know a handful offhand. In addition: Even in times before 8G there were SFPs working much better with certain switches than others.

Utilizing the 8G platform Brocade decided to offer Brocade branded SFPs and restricted their switches to only support them and to refuse others (beside of very few exceptions for CWDM SFPs). So Brocade took control over which SFPs can be used and they were able to fine tune their ASICs to allow better signal handling and transmission. To enforce that the switch checks the vendor information from the SFP to determine if it's a Brocade branded one. Cisco does the same thing for the SFPs in their switches.

Faked SFP vs Third Party SFP

First, we must realize that Third Party SFP isn't faked SFP. If you are seeking further savings on your own network, consider Third Party SFP. When you purchase from a vendor with their own in-house shop, and guaranteed warranty, you get a purchase that's as reliable as new, at a fraction of the original costs. In my opinion, if you have enough budget, It is best to buy the original one. It doesn’t mean that the compatible one is as not good as the original one but you could save more time in thinking about this question. If you care about the cost, compatible one is the best choice, I suggest you choose the OEM manufacturers.

OEM manufacturers Recommendation

Fiberstore is a OEM manufacturer that provide customized solutions for fiber optics needs, As a Cisco OEM SFP transceiver provider, they offer a series of Cisco comaptible SFP modules which can be equivalent to Cisco GLC-T, Cisco GLC-SX-MM, Cisco GLC-LH-SM, Cisco GLC-ZX-SM, and Cisco CWDM SFP, Cisco DWDM SFP, etc. All their SFP transceivers are 100% compatible with major brands as follows and backed by a lifetime warranty.

How to Install or Remove QSFP Transceiver Module

QSFP/QSFP+ Installing Steps

Step 1: Attach an ESD wrist strap to yourself and a properly grounded point on the chassis or the rack.

Step 2: Remove the QSFP+ transceiver module from its protective packaging.

Step 3: Check the label on the QSFP+ transceiver module body to verify that you have the correct model for your network.

Step 4: For optical QSFP+ transceivers, remove the optical bore dust plug and set it aside.

Step 5: For transceivers equipped with a bail-clasp latch: a. Keep the bail-clasp aligned in a vertical position. b. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 6: For QSFP+ transceivers equipped with a pull-tab: a. Hold the transceiver so that the identifier label is on the top. b. Align the QSFP+ transceiver in front of the module's transceiver socket opening and carefully slide the QSFP+ transceiver into the socket until the transceiver makes contact with the socket electrical connector.

Step 7: Press firmly on the front of the QSFP+ transceiver with your thumb to fully seat the transceiver in the module's transceiver socket. Please Note: If the latch is not fully engaged, you might accidentally disconnect the QSFP+ transceiver module.

Step 8: For optical QSFP+ modules, reinstall the dust plug into the QSFP+ transceivers optical bore until you are ready to attach the network interface cable. Please Note: Do not remove the dust plug until you are ready to attach the network interface cable.

QSFP/QSFP+ Removing Steps

Step 1: For optical QSFP+ transceivers, disconnect the network interface cable from the QSFP+ transceiver connector.

Step 2: For QSFP+ transceivers equipped with a bail-clasp latch. a. Pivot the bail-clasp down to the horizontal position. b. Immediately install the dust plug into the transceivers optical bore. c. Grasp the sides of the QSFP+ transceiver and slide it out of the module socket.

Step 3: For QSFP+ transceivers equipped with a pull tab latch a. Immediately install the dust plug into the transceiver's optical bore. b. Grasp the tab and gently pull to release the transceiver from the socket. c. Slide the transceiver out of the socket.

Step 4: Place the QSFP+ transceiver into an antistatic bag.

Note: In fact, the installing or removing steps of the mentioned transceiver modules are the general case. Different transceiver modules of different brands have their own features. We should ask the vendor to get more informations when you face a problem that we do not mentioned here. In addition, to save more money, we suggest that compatible 3rd transceiver modules may be another good choice but you should ensure that your vendor is reliable.

What Is The Difference Between Singlemode SFP and Multimode SFP

The singlemode SFP and multimode SFP here mean the SFP transceivers which work at different types of optical fibers, ie simglemode SFP will work with singlemode fiber, while multimode SFP will work with multimode fiber. So, what’s the different between them? And what should we notice when using them. Today, we are going to have a discussion around this topic.

Singlemode SFP vs Multimode SFP

Singlemode SFP
Singlemode fiber (SMF) has much tighter tolerances for optics used. The core is smaller and the laser wavelength is narrower. This means that SMF has the capability for higher bandwidth and much longer distances in transmission. Singlemode SFPs (SMF SFPs) work mainly in 1310nm and 1550nm wavelength and is mostly used in long distances transmission environment reaching 2km, 10km, 40km, 60km, 80km and 120km. The color coded bale clasp and color arrow on label are generally blue, yellow or purple. And the color of compatible fiber optic patch cord is yellow.

• Blue is the 1310nm module
• Yellow is the 1550nm module
• Purple is the 1490nm module

Multimode SFP
Multi-mode fiber (MMF) uses a much bigger core and usually uses a longer wavelength of light. Because of this, the optics used in MMF have a higher capability to gather light from the laser. In practical terms, this means the optics are cheaper. The common multimode SFPs (MMF SFPs) work in 850nm wavelength and is only used for short distance transmission reaching 100m and 500m. Though it’s not able to transport for long distance, it can transport many kind of optical signals. Their color coded bale clasp and color arrow on label are black and the used fiber optic patch cord is usually orange.

What Should We Notice When Using Singlemode SFP & Multimode SFP

• Ensure that the SFPs in both ends of the fiber patch cord are of the same wavelength. A simple method is that the color of the modules must be consistent.
• In general, to ensure the data accuracy, short-wave SFP modules use with multimode fibers (ie. orange fiber patch cord), while long-wave SFP modules use with single-mode fiber (ie. yellow fiber patch cord).
• Do not over bend or winding fiber optic cables when using them. This will increase the attenuation of light in transit.
• If you don’t use the SFP, you must use the dust plug to protect the optical bore.

Warm Tips
As we know, single mode and multimode are not interchangable. The main reason is the wave length of the laser and core size of the fiber. However, take Cisco SFP for example, there is a type of the GBIC SFP module (part number “SFP-GE-L” or “GLC-LH-SM“) which can support both single mode and multimode fiber. SFP-GE-L and GLC-LH-SM are 1000BASE-LX/LH SFP transceivers. But a mode-conditioning patch cord is required when using the SFP-GE-L or GLC-LH-SM with 62.5-micron diameyer MMF. You must install a mode-conditioning patch cord between the GBIC module or SFP module and the MMF cable on both the transmit and the receive ends of the link when link distances are greater than 984 ft (300 m). In this case, Cisco do not recommend using the SFP-GE-L or GLC-LH-SM and MMF with no patch cord for very short link distance (tens of meters). The result could be an elevated bit error rate (BER). Actually, other brand, like Brocade, also can offer the similar SFP module.

When we choosing the SFP module, we must confirm the transmission distance and wavelength we want to use in. This will help us to choose the right SFP modules more efficiently. In addition, the costs for transceiver modules which keep adding up over time will be a budget pressure for many users. To save more, we can choose the compatible module without sacrificing any quality or reliability but only with a low cost. Fiberstore, an excellent supplier, supplies 100% compatible fiber optic transceiver modules of many brands, such as Cisco, HP, Juniper, Brocade, Finisar etc. with a incredible discount that may be a good choice for you.

Difference between Cisco SFP Module GLC-SX-MM and GLC-SX-MMD

With the widespread used with the Cisco switches and routers, Cisco's GBIC transceivers and Small Form-factor Pluggables (SFP) transceivers for Gigabit Ethernet and Fibre Channel applications have also been popular in the market. These small, modular optical interface transceivers offer a convenient and cost effective solution for the adoption of Gigabit Ethernet and Fibre Channel in data center, campus, metropolitan area access and ring networks, and storage area networks. The 1000BASE-SX SFP (ie, the GLC-SX-MM and GLC-SX-MMD) is one of the common types of Cisco SFPs. Compatible with the IEEE 802.3z 1000BASE-SX standard, it operates on legacy 50 μm multimode fiber links up to 550 m and on 62.5 μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. It can support up to 1km over laser-optimized 50 μm multimode fiber cable.

Due to the similar model, users are usually confused with the Cisco GLC-SX-MM and GLC-SX-MMD when they are choosing the SFP modules. So, what's the difference between them? We are going to talk something about the difference between GLC-SX-MM and GLC-SX-MMD in this paper.

As their models suggest, there is only little difference between GLC-SX-MM and GLC-SX-MMD, Obviously the "D". Here, letter D in the model means the DOM functionality. DOM stands for Digital Optical Monitoring. Digital Optical Monitoring (DOM) is an industry wide standard, intended to define a digital interface to access real-time operating parameters such as:

• Optical Tx power
• Optical Rx power
• Laser bias current
• Temperature
• Transceiver supply voltage

Which means you can configure your device to monitor optical transceivers in the system, either globally or by specified ports. When this feature is enabled, the system will monitor the temperature and signal power levels for the optical transceivers in the specified ports. Console messages and syslog messages are sent when optical operating conditions fall below or rise above the XFP or SFP manufacturer’s recommended thresholds. It is an useful function and now is very popular with users.

It is worth noting that the GLC-SX-MM SFP has been no longer for sale since March 8, 2013 in Cisco. It is entirely replaced by GLC-SX-MMD. Cisco official encourages the customers to migrate to new model SFP transceiver modules. However, for usage and cost considerations, many users still use the old model SFPs. GLC-SX-MMD is much more expensive than GLC-SX-MM, but except the additional DOM function, they work as the same when use in the switch. This is why GLC-SX-MM is still used by many users. To a great extent, this situation is caused by the cost. Fiberstore offers a low cost option for you in both GLC-SX-MM and GLC-SX-MMD. No matter you still like to use the GLC-SX-MM, or wanna replace the new version GLC-SX-MMD, you can find the corresponding products in Fiberstore with a very low price and do not worry about the quality because all of Fiberstore's Cisco compatible SFP modules are tested in-house prior to shipment to guarantee that they will arrive in perfect physical and working condition before delivered worldwide. In addition, there is a big stock of these two products, you can enjoy the same-day shipping when you order them in Fiberstore.

The General Concerns of Using Cisco Compatible SFP

It seems to be an old topic that whether using compatible fiber optic transceiver is reliable. We have already discussed this topic few weeks ago. Without a doubt, the answer is affirmative.

However, I have found that there are still many questions about this topic in many forums, Q & A sites etc, and most of them are about 1000base t sfp transceiver or other compatible SFP modules. As we know, Cisco is the worldwide leader in networking that transforms how people connect, communicate and collaborate, and owns the most of the switching and routing markets, ie. there are plenty of users of Cisco. In order to ensure the safety and smooth communication of the system, a good switch or router is very necessary, but the costs for other components, such as Cisco SFP modules, usually can add up over time. Due to the open standard of the fiber optic transceiver, the compatible modules have been emerged as the times require. Compared to the original brand, the low cost is really the attractions of of the compatible one. However, it is precisely because the incredible low price, many users usually worry about the quality. This is why we often find the discussion about the compatibility.

Today, I am going to continue the topic about the reliability of Cisco compatible transceiver module through a post in Yahoo Answer. The source of the post.

After reading the post, we found that it is a general situation when we decide to buy some SFP modules for your Cisco devices. In the post, the poster want to buy some SFP modules of the model “glc-sx-mmd“. In general, if we have enough budget, we will buy the Cisco original without the slightest hesitation. Maybe just wanna choose some proper suppliers, or wanna save more, he surfs on the Internet and finds a supplier that offers Cisco SFP only on sale $ 8.00. “it is incredible, is it real?” We can hear him from his tone full of surprise. Through visiting the link he gave, we can know the $ 8.00 Cisco compatible SFP is one of the products of Fiberstore.

Do you have a similar experience like the poster? I think, many users have. But to this qustion, there were divergent views that we can easily see from the answer in this post.

The answer of Yahoo user “I Like Stories” has been selected by the poster as the best answer that give us a full answer of his opinion as well as the reason why original modules is so expensive.

Although he has not clearly indicated whether the compatible modules should be chosen, his opinion is objective.

In most cases, we are biased in favour of the original one due to the stability and good after-sale service of Cisco, or other famous brand. As we said above, if the budget is enough, the original one is the best choice. However, the continued cost of the SFP is too much for many enterprise or lab. In front of the limitation of the cost, a good quality and competitive price module becomes very necessary. That’s why the compatible SFP modules are popular in the market.

From the other comments or the similar topics in many forums, we are not difficult to discover that most of the users have the experience of using Cisco compatible SFP (eg. 1000base sx SFP, cisco glc zx smd, sfp ge t 100 mbps module, etc.). And few of them have bad impression, except some complaints when applied in high security environment, the compatible one not work well as the original one, or even the wrong selection of an unqualified vendor or using the products of bad quality.

Actually, about the definition of the third party SFP transceiver, there is an explanation of the compatibility. If a device requires coded SFP modules (i.e. Cisco / HP) then you need either the OEM module or a compatible version. If the device does not require coded SFP (i.e. Netgear) then you can use any SFP, even a Cisco. In fact, many times, the main concerns of using compatible SFP is the quality and after sale service. If your supplier tells you their compatible SFP is 100% compatible with Cisco’s or any other brands, then you can rest assured to buy as now many suppliers have the service of lifetime warranty, but the premise is you shoud choose a good supplier. Using compatible SFP modules (eg. Cisco, Dell and Allied telesis SFP etc.) is that you won’t sacrifice any quality or reliability with all of the savings you receive. In fact, you get everything you’ve come to expect from Cisco SFPs at a low cost.

OK, at last, we return to the post of Yahoo answer. Is the $ 8.00 Cisco compatible SFP reliable? If it is offered by other suppliers, I can’t ensure it to you. But it is from Fiberstore, I think I can guarantee its authenticity and quality not to mention the other, just from the reviews. In addition, many famous enterprises in the world also use Fiberstore’s products. The blog of CloudFlare had mentioned Fiberstore’s SFP+ modules in their news about the latest generation servers — “We spent significant time testing a combination of SFP+ vendors before finding Fiberstore, a SFP+ manufacturer from which we could directly source SFP+s at a reasonable price that worked in the network gear we wanted to use.”

So, what’s your opinions? In my opinion, if you have enough budget, I suggest you to buy the original one. It doesn’t mean that the compatible one is as not good as the original one but you could save more time in thinking of this question.  If you care the cost, compatible one is the best choice, but you should choose a good supplier as the premise. If you are still confused by the similar question, I hope this article will give you some helps.

Optical Transceivers for FIs

Understanding FIs

A FI is the core component of a UCS solution. FIs are typically configured as highly available clustered pairs in production environments. It’s possible to run a single FI-based design as a proof of concept test deployment before actually implementing it in production. FIs provide the following two capabilities:

1. Network connectivity to both LAN and SAN
2. UCS infrastructure management through the embedded management software, UCSM, for both hardware and software management

FIs are available in two generations, namely Cisco UCS 6100 series and Cisco UCS 6200 series. The core functionality is the same in both generations; however, UCS 6200 series has a newer generation Application Specific Integrated Circuit (ASIC), higher throughput, and increased number of physical ports. Both generations can be upgraded to the latest UCSM software.

FIs provide converged ports. Depending on the physical Small Form Factor Pluggable (SFP) transceivers and FI software configuration, each port can be configured in different ways. Cisco 200 series FI ports can be configured as Ethernet ports, Fiber Channel over Ethernet (FCoE) ports, or Fiber Channel (FC) ports. On the other hand, 6100 series converged ports only support Ethernet and FCoE (they also support FC, but only in the expansion slot).

In production, FIs are deployed in clustered pairs to provide high availability. Cisco-supported implementation requires that clustered FIs be identical. The only possibility for having different FIs in a cluster is during a cluster upgrade.

Exploring Connectivity Transceivers for FIs

A variety of SFP transceivers are available for The Cisco UCS 6200 series. These transceivers provide south-bound IOM connectivity and north-bound network and storage connectivity. They are based on industry-standard SFP+ specifications.

Transceivers can be selected depending on the technology, for example, Ethernet or FC, and also according to the distance requirements. For shorter distances between FIs, IOMs, and north-bound network switches, twinax cables with integrated SFP is an economical alternative as compared to fiber optic SFP.

The most commonly used transceivers include following:

• Cisco SFP-10G-SR: This is a multimode optical fiber 10Gbps Ethernet SFP that can be used for distances up to 400 meters.
• Cisco SFP-10G-LR: This is a single-mode optical fiber 10Gbps Ethernet SFP that can be used for distances up to 10 Km.
• Cisco SFP-10G-TET: This is a low power consuming multimode fiber optic 10Gbps Ethernet SFP that can be used for distances up to 100 meters.
• Cisco SFP-H10GB-CuxM: These are the twinax cables providing low cost 10Gbps Ethernet connectivity and are available in 1, 3, 5, 7 and 10 meter configurations.
• Cisco SFP-H10GB-ACU10M: This is a 10-meter-long twinax cable providing 10Gbps Ethernet. At a length of 10 meters, this cable requires active transceivers at both ends.
• Cisco GLC-T: 1000BASE-T SFP or SFP-compatible ports only,these are based on the SFP Multi Source Agreement (MSA) and compact RJ-45 connector assembly. For SFP-compatible ports only.
• Cisco GLC-SX-MMD: These modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 550m transmission distance with MMF, for SFP-compatible ports only.
• Cisco GLC-LH-SMD: These modules supporting dual data-rate of 1.25Gbps/1.0625Gbps and 10km transmission distance with SMF, for SFP-compatible ports only.
• DS-SFP-FCxG-xW: These are multi-mode and single-mode fiber optic FC transceivers that are available at 2, 4, and 8Gbps transfer speeds.

Where to buy These Optical Transceivers

Fiberstore provide a full range of optical transceivers, such as SFP+ (SFP Plus) transceiver, X2 transceiver, XENPAK transceiver, XFP transceiver, SFP (Mini GBIC) transceiver, GBIC transceiver, CWDM/DWDM transceiver, 40G QSFP+ & CFP, 3G-SDI video SFP, WDM Bi-Directional transceiver and PON transceiver. All our fiber transceivers are 100% compatible with major brands like Cisco, HP, Juniper, Nortel, Force10, D-link, 3Com. They are backed by a lifetime warranty, and you can buy with confidence. We also can customize optical transceivers to fit your specific requirements.

Cisco GLC-LH-SMD Compatible SFP For Your Network

With the development of the businesses, must also have the development of the networks.This is a cannot be avoidable side-effect of expansion and maturation in a company.

If you meet the point, you just begun to consider buying a larger property, or being planned in another workplace. You may return to the past ten years of the limitations of technology. Standard baseT100 Ethernet is fine for a small office, but it isn't suitable for handling heavier network use. Since your network expands, you may experience problems like:

• Dropouts in your VoIP calls
• Sluggish data retrieval speeds
• Spotty WiFi coverage across a large areas
• Difficulty leveraging Cloud-based applications
• Or poor video streaming quality

If any of this sounds familiar, it might be time for you to start considering upgrading to gigabit Ethernet, which fast at 10 times the speed of traditional Ethernet.

Twisted Copper vs Fiber Optic Gigabit Ethernet

Another major consideration would be to determine whether or not you need to keep using copper-wire cabling or upgrade to fiber optic cabling in your offices. It's more costly, but fiber optic provides several benefits over copper, while still supplying the same gigabit speeds.

Fiber optic cable supports far longer cable lengths than twisted copper. Copper can only run for around 100 meters, whereas fiber can go between 200 and 500 feet, or even more, without signal loss.

Fiber has gives off no radio interference, letting it to coexist easier in an office with a lot of wireless devices. Because of the lack of interference, fiber is also harder to hack into than copper. Just as with copper, a standard GLC-LH-SMD transceiver links fiber optic Ethernet with your existing equipment.

If you have looked ahead to the future, leaving copper might be a good choice. Fiber optics are increasing steadily in popularity among businesses that have taken over largetwisted-copper office buildings, created expansive complexes, or have an obligation to collaborate with remote offices immediately.

Using GLC-LH-SMD Transceiver To Connect Fiber Optic Network

The greatest benefit of Cisco SFP product is just entirely hot-swappable. No matter what the device is, it from servers to your switch to simple Ethernet cards: If it includes a SFP port on it, it could support many transceivers for different functions, through one standardized interface. In fact, that standardization shows that compatible modules can produce transceivers which are as good as official Cisco units. (cisco compatible sfp transceiver)

Cisco even has a compatible Matrix, that will help you select the best transceiver to do the job. So, if you think that fiber optic gigabit Ethernet is exactly what you require for your future business communications needs, the GLC-LH-SMD transceiver is truly easy to install and utilize. Simply plug it on your switch or any other device, plug in the brand new network cable, and it should recognize the network in a few moments.

There are a few different gigabit Ethernet standards to choose from. So you must research and think which is the most suits for your situation or for the future of your business. Just remember that you will need transceivers such as the GLC-LH-SMD to connect your current devices to the new network.
