Finisar’s FTLX8574D3BCL 10Gb/s SFP+ transceivers are designed for use in 10-Gigabit Ethernet links over multimode fiber. They are compliant with SFF-8431 1 , SFF-8432 2 , IEEE 802.3-2012 10GBASE-SR/SW 3 and 10G Fibre Channel 1200-Mx-SN-I 4. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472 5 . The FTLX8574D3BCL 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 optical transceiver is compliant per the RoHS Directive 2011/65/EU 6 .
