Introduction to Four Popular Types of Finisar SFP Optic Transceivers

Sep 24th 2015 at 12:54 AM

Finisar’s broad product selection and innovative technology have made us the optical module manufacturer of choice for all major networking equipment vendors worldwide. They have taken a leading role in transforming the datacommunications and telecommunications equipment market from utilizing discrete optical components to leveraging the design and pay-as-you-grow flexibility offered by pluggable modules. Their modules are capable of distances ranging from very short reach within a data center to campus, access, metro, and long-haul reaches. They feature outstanding performance over extended voltage and temperature ranges. This article will introduce Finisar’s four popular SFP (Small Form Pluggable) transceivers to you.

Finisar FCLF-8521-3 1000BASE-T Copper SFP

Finisar FCLF-8521-3 1000BASE-T Copper SFP transceivers are based on the SFP Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE 802.32 standards. The FCLF-8521-3 is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded). However, the FCLF-8520-3 uses both the SFP’s RX_LOS pin and auto-negotiation for link indication. If you want to know more about the differences between FCLF-8521-3 and FCLF-8520-3, I recommend you to read the article—Frequently Asked Questions Regarding Finisar’s 1000BASE-T SFPs.

FCLF-8521-3

Finisar FTLF1318P3BTL 1000BASE-LX SFP

Finisar FTLF1318P3BTL SFP transceivers are also compatible with the MSA. They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.31 and 1x Fibre Channel as defined in FC-PI-4 Rev. 8.003. They are RoHS compliant and leadfree per directive 2002/95/EC5. Finisar FTLF1318P3BTL SFP supports the duplex LC connector and can reach up to 10 km on single-mode fiber. Besides, digital diagnostics functions are available via the 2-wire serial bus specified in the SFP MSA.

Finisar FTRJ1319P1BTL Dual Rate 1000BASE-LX SFP

Finisar FTRJ1319P1BTL SFP is compatible with the Gigabit Ethernet and 1000BASE-LX standards. They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.31 and 1x and 2x Fibre Channel as defined in FC-PI 13.03. Industrial operating temperature range of the FTRJ1319P1BTL is from -40°C to 85°C. Like the Finisar FTLF1318P3BTL SFP, digital diagnostics functions are available with the FTRJ1319P1BTL via the 2-wire serial bus specified in the SFP MSA.

Finisar FTLX1471D3BNL 10GBASE-LR SFP

Finisar Extended Temperature FTLX1471D3BNL 10Gb/s Enhanced SFP transceivers are designed for use in 10-Gigabit Ethernet links up to 10km over single-mode fiber. They are compliant with SFF-84311, SFF-84322, IEEE 802.3ae 10GBASE-LR/LW3 and 10G Fibre Channel 1200-SM-LL-L4 . The FTLX1471D3BNL is a “limiting module”, that is to say it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturer’s recommended settings for interoperating the host-board EDC PHY with a limiting receiver SFP+ module. The FTLX1471D3BNL is RoHS compliant and lead free per directive 2002/95/EC6.

After reading this article, you may get some knowledge of several types of Finisar SFP optic transceivers. Fiberstore offer all Finisar compatible SFPs, such as the SFP-1GT-1MB, which has the same functions with the Finisar FCLF-8521-3. For more information, please visit Fiberstore.com.
