PRELIMINARY Product Specification RoHS-6 Compliant 10Gb/s 220m Multi Mode Datacom SFP+ Transceiver FTLX1371D3BCL PRODUCT FEATURES • • • • • • • • • • • Hot-pluggable SFP+ footprint Supports 9.95 to 10.3Gb/s bit rates Power dissipation < 1W RoHS-6 compliant (lead-free) Commercial temperature range -5°C to 70°C Single 3.3V power supply Maximum link length of upto 220m Uncooled directly modulated Fabry-Perot (FP) laser at 1310 nm Receiver linear electrical interface Duplex LC connector Built-in digital diagnostic functions APPLICATIONS • • 10GBASE-LRM 10G Ethernet Legacy FDDI multimode links Finisar’s FTLX1371D3BCL 10Gb/s Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 220m over Multi Mode fiber. They are compliant with SFF-84311, SFF-84322 and IEEE 802.3 aq3 10GBASE-LRM. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-84724. The FTLX1371D3BCL is a “linear module” i.e. it employs a linear 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 linear receiver SFP+ module. The transceiver is RoHS compliant and lead-free per Directive 2002/95/EC5, and Finisar Application Note AN-20386. PRODUCT SELECTION FTLX1371D3BCL © Finisar Corporation - April 28, 2008 DRAFT Rev. A3 Page 1 FTLX1371 PRELIMINARY Datacom SFP+ Product Specification – April 2007 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).

Block Diagram of SFP+ LRM Module on Host Board with EDC 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. © Finisar Corporation - July 25, 2008 DRAFT Rev. A3 Page 2 FTLX1371 PRELIMINARY Datacom SFP+ Product Specification – July 2008 II.
