Choose and Get SFP+ Module and Cables Effectively

According to the standard of the IEEE 802.3 ae committee ratified the 10 Gigabit Ethernet and the general specification, it defines a number of fiber optic interfaces. These standard interfaces attempted to satisfy a number of different objectives including support for MMF and SMF compatibility. They include 10GBASE-SR SFP transceiver, 10GBASE-LR SFP transceiver, 10GBASE-ER SFP transceiver, 10GBASE-ZR SFP transceiver, copper CU SFP+, maybe someone does not know the last one, related product you can see: Cisco SFP-H10GB-CU1M. Their applications are using 10 Gigabit Ethernet and 2x/4x/8x/16x Fiber channel, for example, the cisco SFP+ module, the optical interoperability with 10Gbase XENPAK, 10 GBase X2, and 10GBase XFP interfaces on the same link; the device can plug into an Ethernet SFP+ port of a Cisco switch, just do not need to power down if installing or replacing, these are all its advantages. The Cisco quality ID feature enables a Cisco platform to identify whether the module is certified and tested by Cisco. Then many people also think this problem that when we use the cisco transceiver with cisco switches or even patch cables, do they need the vendor ti physically hang the access points and do they need to configure the access points and how many buildings will the access points be installed into, well, the next paragraph will give you the answer. The vendor needs to physically hang the access points and the points are controller based and they will need to be configured. All access points are to be installed on the ceiling, the only exception would be in gym where it would to be mounted to the ceiling beam. The figure shows that push the SFP front of the module to make it into the slot.

Many people know that SFP, SFP+ and they are not familiar with QSFP, then i will introduce one kind of QSFP transceiver to you. The 40 Gb/s QSFP+ transceiver. It is a kind of fiber optical modules with four independent optical transmit and receiver channels. It combines the higher density attractions of modules with some the key advantages normally associated with SFP+ based modules. And another product you also cannot forget: sfp+ direct attach cable. In Fiberstore, there is a similar attach cable, sfp+ direct attached twinax copper, it is suitable for very short distances and offer a useful way to connect within racks and across adjacent racks. Cisco offers passive twinax cables in lengths of 1, 1.5, 2, 2.5, 3 and 5 meters, and active twinax cables in lengths of 7 and 10 meters. Related product: twinax cable 0.5 m.

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.

Fiberstore Direct Attach Cables

Meeting the ever growing need to cost-effectively deliver more bandwidth, Fiberstore SFP+ Direct Attached Cables deliver lower power, lower latency and higher density for today's Data Centers and Storage Area Networks.

SFP+ Direct Attached Cables are a low cost alterna-tive to traditional fiber and twisted-pair copper cabling in top-of-rack and middle-of-row Data Center deployments.

In today's Data Center, more bandwidth is needed to support the use of server virtualization where multiple virtual machines are combined on a single physical host server. To accommodate the ever-growing number of operating systems and applications residing on individual servers, virtualization requires significantly increased data transmission between the servers and switches.

At the same time, the amount and type of devices residing on the network have dramatically increased the amount of data that needs to be transmitted to and from storage area networks (SANs) and Network Attached Storage (NAS). Depending on recent industry forecasts, the amount of enterprise data being transmitted will grow at more than 20% between 2011 and 2016. Consequently, Data Center managers are looking for cost-effective methods to provide more bandwidth, while optimizing power consumption and supporting modularity and scalability.

To meet these requirements, Fiberstore has expanded its line of Data Center Solutions to include SFP+ Direct Attached Cables. A low cost, low power consumption and low latency solution that is ideal for high-density, in-rack 10 gigabit per second (Gb/s) connections between servers and switches, SFP+ Direct Attached Cables feature rugged twinaxial cables that connect directly into a low-profile small form-factor pluggable plus (SFP+) diecast connector housing.

Fiberstore SFP+ Direct Attached Cables offer the smallest 10 gigabit form factor and a small overall cable diameter for higher density and optimized rack space in 10 gigabit Ethernet (GbE) uplinks and 10 gigabit Fiber Channel SAN and NAS input/output connections. The use of SFP+ Direct Attached Cables can cost up to three times less than fiber optic solutions, while offering lower latency and consuming up to 50% less power per port than current copper twisted-pair cabling systems.

Becoming increasingly popular for short distance top-of-rack (ToR) and middle-of-row (MoR) Data Center deployments, and expected to account for over 40% of 10 gigabit equipment ports, SFP+ Direct Attached Cables also provide enhanced scalability and flexibility. By connecting several servers or storage devices together in a single rack, the use of intermediate patch panels is eliminated and cabling outside of the rack is limited to the main switch connection, making it easy to move racks, deploy one rack at a time and isolate cabling changes to a single rack.

SFP+ Direct Attached Cables provide better cable management for high-density deployments and enhanced electrical characteristics for the most reliable signal transmission.

How Much do You Know About 10/100/1000BASE-T SFP Transceivers?

10/100/1000BASE-T SFP

is a triple-speed 1000BASE-T/100BASE-TX/10BASE-T IEEE 802.3az Gigabit transceiver integrated into a single monolithic CMOS chip. It can be used for both Fast Ethernet and Gigabit Ethernet applications.

This kind of SFP module supports 10/100/1000BASE-T operation in host systems with Serial Gigabit Media Independent Interface (SGMII), and with it the host systems needn't to support 1000BASE-T autonegotiation. The 10/100/1000BASE-T SFP module uses the 1000BASE-X autonegotiation information it receives from the host to adjust the configuration options that it advertises during copper autonegotiation. To the host system, the 10/100/1000BASE-T SFP will appear to be a fiber transceiver. From the host's perspective, acknowledgements received during the 1000BASE-X autonegotiation process are coming from the remote link partner even though they are coming from the 10/100/1000BASE-T SFP.

The 10/100/1000BASE-T SFP transceiver performs all physical-layer functions for 1000BASE-T, 100BASE-TX, and 10BASE-T Ethernet on standard Cat 5 UTP cable of link lengths up to 100 m (328 ft). 10BASE-T can also run on standard category 3, 4, and 5 UTP. You can safely use Cat 5e or Cat 6 cables, as these are improved versions of Cat 5. For short cable runs, with intricate routing, stranded cable is recommended, as it is more flexible.

Tips: SGMII is a mode of communication between the MAC and PHY to allow for 10/100/1000BASE-T operation. In 100BASE-TX mode, the MAC still transmits to the PHY at 1.25 Gbps, but each byte is repeated 10 times. The PHY then converts this repeated data to 100BASE-TX format. The process is the same in 10BASE-T mode but each byte is repeated 100 times.

Where can we get such cost-effective transceivers? I think most people will think about Cisco, HP, Juniper etc. But their products are not cost-effective at all. As I know, the Finisar SFP modules might be a wiser choice. The part number of Finisar copper 10/100/1000 SFP that supports 10/100/1000 autonegotiation is FCLF-8521-3. The FCLF-8521-3 is based on the proven digital signal processor technology, combining digital adaptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders, echo cancellers, crosstalk cancellers, and all other required support circuitry integrated into a single chip. With full compliance to IEEE 802.3az standard, the FCLF-8521-3 substantially lower power consumption during periods of low-link utilization.

Finisar FCLF-8521-3 compatible SFP offered by Fiberstore cost only 15 dollars now. Compared to the original price, we can save almost 80% by using Finisar compatible SFPs. See more Finisar SFP+ modules.

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.

Fiberstore SFP+ Cables

SFP+ fiber cable solution is suitable for longer distance communication, while 10G SFP+ cables solution is best when utilized in short lengths, typically 15m or less, which is sufficient to link server cards and switches. But at present, the fiber and copper cable transmission standard of 10G Ethernet have been launched. However, there is only the fiber standard without copper standard for the 40G Ethernet transmission now.

QSFP+ cables and SFP+ cables

From the perspective of the development of wiring, generally, the standard of copper cable is always behind the fiber standard and the application standard. Currently, the TIA and ISO have already established a working group to carry out the research work of the copper standard.

Actually, the QSFP+ cable is a choice for short transmission distance. Generally, QSFP+ cables are used to connect the ToR switches.

Fiberstore QSFP+ Cables

QSFP+ cable and sfp+ direct attach cable are both suitable for the short transmission distance. The fiber can be considered for the long transmission distance. The standard distance of OM3 multi-mode fiber is 100m and the OM4 is 50m. The single-mode fiber will not encounter the problem of transmission distance. Fiberstore provides qsfp 4x10g aoc7m.

For the high-density, high-performance, longer distance and high-speed and other requirements, the MPO/MTP will be a more reasonable choice.

About Optical Transceivers

Optical transceivers are available in many different sizes and support many different cabling media and application speeds. You may hear words like, GBIC, mini-GBIC, SFP, SFP+, XFP and others. These support different rates and have different form factors.

A Gigabit Ethernet interface converter (GBIC) is a standard used for the kind of optical transceivers that can be plugged into switches and media converters. This method of plugging a transceiver into a GBIC module slot of a switch, as opposed to having a fixed interface, is also called hot-swappable since the transceiver is loaded into the switch while the switch is powered on. The GBIC standard is determined in the SFF Committee in document number SFF-8053. GBIC transceivers are offered in the -SX, -LX, and -ZX wavelengths and media ranges.

GBICs were created to provide both a small form factor and the flexibility to plug a number of transceiver types into a common electrical interface for Gigabit Ethernet speeds. When a variety of optical port types are needed, an IT administrator can buy GBICs as needed. This lowers the expense of the overall switch system and gives the IT administrator much more flexibility, since they have the choice of different transceiver types. However, if the switch is intended to mostly have one port type, then it will probably be cheaper and take up less space per port to use a switch with that port type built into it. The back of the device has an electrical adapter that plugs into a switch. The front of the transceiver has a SC connector interface for the two 850nm optical ports suitable for use over multimode fiber. One is used for transmitting and the other for receiving signals.

A smaller kind of the GBIC is called a mini-GBIC or SFP (small form factor pluggable) module. It serves the same purpose as the GBIC but has a smaller footprint. To allow for the smaller footprint, SFPs use LC connector interfaces. SFPs are also offered a 1000-Base-T reference to an RJ-45 interface.

The XENPAK transceiver was standardized in 2001 to support 10 Gigabit Ethernet over fiberoptic media and copper media. These come in a number of optical media types and wavelength ranges and also support copper media using a -CX4 interface. They're much bigger in dimension than GBICs and SFPs. After XENPAK was standardized, XPAK and X2 are created to supply a smaller footprint for 10 Gigabit Ethernet. These products share exactly the same electrical interface as XENPAK but are lighter. The XFP small form factor pluggable transceiver was initially developed in 2003 to supply a smaller form factor transceiver for 10Gbps applications than XENPAX, XPAK, and X2 transceivers.

XFP was created by the XFP Multi-Source Agreement Group prior to the development of the SFP+. XFPs supports 10 Gigabit Ethernet, SONET/SDH, and Fibre Channel applications. In keeping with their small form factor, much like SFPs, XFPs use an LC connector interface. XFPs are set up in a similar fashion to GBICs and SFPs, are available in many media type and wavelengths.

The SFP+ transceiver module was created later to assistance 10 Gigabit Ethernet speeds. It's about 30 percent smaller than an XFP, consumes less power, and is more cost-effective. Figure 1 shows various of transceivers.
