Metro Access Rings and Point-to-Point
networking for Gigabit Ethernet and
Fibre Channel
Finisar’s FWLF15197Dxx CWDM Small Form Factor Pluggable (SFP) transceivers are
designed for operation in Metro Access Rings and Point-to-Point networks using Gigabit
Ethernet and Fibre Channel networking equipment. They are available in eight different
CWDM wavelengths. Digital diagnostics functions are available via a two wire serial
bus. In addition, the transceivers comply with the Small Form Factor Pluggable Multi-
Sourcing Agreement (MSA)
