. This product is for applications specifically designed for 10G SFP+ ports and 

1G/10G SFP+ ports and not native 1G SFP ports. The FTLX1471D3BCV 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
