Finisar’s Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM
transport with dramatically lower power and cost in a standard pluggable Small Form
Factor Pluggable (SFP) package1. The FWLF-1631 is designed expressly for service
providers deploying DWDM networking equipment in metropolitan access and core
networks2. The transceiver is RoHS compliant and lead free per Directive 2002/95/EC3,
and Finisar Application Note AN-20384.
Basic digital diagnostic features for the FWLF-1631 are implemented as described in
Finisar Application Note AN-2030, “Digital Diagnostic Monitoring Interface for Optical
Transceivers”5. Optional enhanced digital diagnostic features are available per the
