Selecting an SFP

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.
