The Intel FTLX1471D3BCV-IT 1G/10G Dual-Rate SFP+ transceivers are designed for use in 1-Gigabit and 10-Gigabit Ethernet links up to 10km over singlemode fiber. They are compliant with SFF-8431, IEEE 802.3-2005 10GBASE-LR/LWand 1000BASE-LX. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472. This product is for applications specifically designed for 10G SFP+ ports and 1G/10G SFP+ ports and not native 1G SFP ports. The FTLX1471D3BCV-IT 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 transceivers arecompliant per the RoHS Directive 2011/65/EU. See Finisar Application Note AN-2038 for more details.
