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.

SFP transceiver is hot-swappable in industry-standard cages and connectors, and offers high-speed performance in a compact package. SFP is used to data rates up to 4 Gb/s and DWDM, including tunable versions. SFP and SFP+ (enhanced SFP) transceivers are interchangeable and can be used in the same cages as SFP transceivers. The electrical interface to the host board is a serial interface.

SFP+ is a standardized form factor for fiber optic transceivers and is used in datacom and telecom optical links, supplying a smaller footprint and lower power consumption than XFP transceivers. Initial standard applications focused on 8G Fibre Channel, 10G Ethernet and 10G Fibre Channel, where the electrical interface to the host board is a standardized serial interface called SFI.The applications have broadened to include SONET OC-192, SDH STM-64, OTN G.709, CPRI wireless, 16G Fibre Channel, and the emerging 32G Fibre Channel application.

Finisar’s FTLF8524P2xNy Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA).
They are compatible with Fibre Channel FC-PI-2 Rev. 7.02. Rate Selectable versions are also compatible with Gigabit Ethernet as specified in IEEE Std 802.33. They are RoHS compliant and lead-free per directive 2002/95/EC4 and Finisar Application Note AN-2038. Digital diagnostics functions are available via the 2-wire serial bus set out in the SFP MSA.

Digital Diagnostic Functions
Finisar FTLF8524P2xNy SFP transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
Additionally, Finisar SFP transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature. Laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alert end-users when particular operating parameters are outside of a factory set normal range.
The SFP MSA defines a 256-byte memory map in E2PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The cardinal diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC specification and the SFP Multi Source Agreement. The complete interface is detailed in Finisar Application Note AN-2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”.
The operating and diagnostics information is controlled and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is enabled, the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the E2PROM that are not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to signify the start and end of serial protocol activation. The memories are structured as a series of 8-bit data words that can be addressed individually or sequentially.
