FTLX1371 PRELIMINARY Datacom SFP+ Product Specification – April 2007
© Finisar Corporation - July 25, 2008 DRAFT Rev. A3 Page 2
I. Description
The Finisar FTLX1371D3BCL SFP+ transceiver is a linear-interface transceiver that
enables, in conjunction with an Electronic Dispersion Compensation (EDC) on the
host board, an IEEE802.3aq 10GBASE-LRM compliant link. The host board EDC
provides correction for the severe modal dispersion that may occur during
propagation through multimode fiber links, including legacy installed FDDI
multimode fiber (see IEEE802.3aq for detailed information regarding fiber coverage).

Unlike the XFP MSA transceiver requirements, the SFP+ transceiver does not contain
internal retiming circuitry, and thus some of the Transmitter Optical Characteristics stated
in this data sheet require that the Host Board is compliant to the SFP+ MSA
specifications. See Chapter 3 in Reference [1] for further details.
