Finisar's FTLX8571D3BCL 10Gb/s SFP+ transceivers are designed for use in 10-Gigabit Ethernet bs over multimode fiber. They are compliant with SFF-8431, SFF-8432, IEEE 802.3ae 10GBASE-SR/SW and 10G Fibre Channel 1200-Mx-SN-I. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. The FTLX8571D3BCL 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.  The transceiver is RoHS compliant and lead free per Directive 2002/95/EC, and Finisar Application Note AN-2038
