APPLICATIONS
•
Optical Supervisory Channel for
SONET OC-3 and Fast Ethernet
Finisar’s FWLF1523P1x51 Small Form Factor Pluggable (SFP) transceivers provide a
reliable solution for 1511nm, point-to-point, 155Mb/s Optical Supervisory Channel
(OSC) applications, outside the band of the transmitted signal. They are compatible with
the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA)
1
, as well as with
SONET and SDH standards
2
at OC-3 LR-2/STM L-1.2 and Fast Ethernet applications.
Digital diagnostics functions are available via the 2-wire serial bus specified in the SFP
MSA. They are RoHS compliant and lead-free per Directive 2002/95/EC
3
and Finisar
Application Note AN-2038.

Notes:
1. Compatible with SONET OC-3 LR-2 as the output power is 5dB higher than the OC-3 requirement.
2. Compatible with Fast Ethernet as the performances are tested only with PRBS data saving DC balance.
3. Tested with a PRBS 2
