194 Appendix B Installing SFP and CWDM Gigabit Interface Converters (GBICs)
212859-A
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.
CWDM SFP GBIC Listing
Table 52 lists the Nortel Networks CWDM SFP GBICs and describes their
wavelengths, color codes, part numbers, and cable lengths.
