Finisar’s FTLX1871M3BCL transceivers are Enhanced Small Form Factor Pluggable

SFP+ transceivers designed for use in 10-Gigabit multi-rate links up to 80km of G.652

single mode fiber. They are compliant with SFF-8431

, SFF-8432

and G.959.1 P1L1-

2D2, and support SONET OC-192, SDH STM-64, 10G Ethernet ZR and 10G Fibre

Channel. Finisar’s FTLX1871M3BCL transceivers use internal clock and data recovery

(CDR) IC’s for the transmitter and the receiver. This guarantees compliance with the

SONET/SDH jitter requirements and it can be used to set the electrical interface to be

XFI-compliant.

Digital diagnostics functions are available via a 2-wire serial interface, as specified in

SFF-8472

. Finisar’s FTLX1871M3BCL transceivers are RoHS compliant and lead free

per Directive 2002/95/EC

, and Finisar Application Note AN-2038

FTLX1871M3BCL Multi-rate SFP+ Product Specification VIII. Digital Diagnostic Functions Finisar FTLX1871M3BCL SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFP MSA1. It is very closely related to the E2PROM defined in the GBIC standard, with the same electrical specifications. The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
