Coherent FTLX8574D3BCL 10Gb/s SFP+ Transceivers are designed for 10 Gigabit Ethernet links over multi-mode fiber (MMF). They comply with SFF-8431, SFF-8432, IEEE 802.3-2012 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. Coherent FTLX 8574D3BCL is a "limiting module", meaning 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.
