Nortel Networks 4500 Series - Manual (Page 23)

Selecting an SFP 23
The SFPs described in this section do not have Digital Diagnostic Interface
capability, and are RoHS -E5 compliant.
CWDM SFPS are also supported. CWDM technology consolidates
multiple optical channels on a common optical fiber. CWDM uses multiple
wavelengths to expand available bandwidth.
CWDM SFPs are designed to support high speed data communications
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.
ATTENTION
The attainable cable length can vary depending on the quality of the fiber optic
cable used.
