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
