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 . The optical transceiver is compliant per the RoHS Directive 2011/65/EU .
