APPLICATIONS
SONET OC-192 IR-2/-3
SDH STM-64.2b/3b

Finisar’s FTLX1672M3BCL transceivers are Enhanced Small Form Factor Pluggable
SFP+ transceivers designed for use in 10-Gigabit multi-rate links up to 40km of G.652
single mode fiber. They are compliant with SFF-8431
1
, SFF-8432
2
, SONET OC-192 IR-
2R/3R, SDH STM-64.2b/3b, OTN P1S1-2D2b, 10GBASE-ER/EW and support 8.5G and
10G Fibre Channel. The 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
3
. The optical transceiver is compliant per the RoHS Directive
2011/65/EU

the host board if intended for use. Pull up voltage should be between 2.0V to Vcc + 0.3V. A high
output indicates a transmitter fault caused by either the TX bias current or the TX output power
exceeding the preset alarm thresholds. A low output indicates normal operation. In the low state, the
output is pulled to <0.8V.

LOS is open collector output. Should be pulled up with 4.7k – 10k on host board to a voltage
between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
