Introduction to Coarse Wavelength Division
Multiplexed (CWDM) Small Form Factor
Pluggable (SFP) Gigabit Interface Converters
This section describes how the Nortel Networks* coarse
wavelength division multiplexed Small Form Factor Pluggable
Gigabit Interface Converter (CWDM SFP GBIC) works within
the optical routing system. It also provides a list of CWDM SFP
GBICs by wavelength and shows how they are labeled and color-
coded.
CWDM SFP GBIC description
CWDM SFP GBICs are transceivers that link Gigabit Ethernet
ports with fiber optic networks. WDM technology consolidates
multiple optical channels, using specific wavelengths to expand
available bandwidth, on a common optical fiber.
About the optical routing system
CWDM SFP GBICs are a component in the optical routing
system designed to support high speed data communication for
Metropolitan Area Networks (MANs). The system uses a grid of
eight CWDM optical wavelengths in both ring and point-to-point
configurations. All components are color-coded by wavelength.
