Finisar’s FTLX1671D3BTL 10Gb/s Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 40km over single mode fiber. They are compliant with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-ER/EW. The FTLX1671D3BTL incorporates advanced CML™ technology, and is a “limiting module”, i.e., 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. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF- 8472. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC, and Finisar Application Note AN-2038.
