Environmental and Optical Specifications for Cisco 4-Gbps CWDM SFP Transceivers
Table B-32 provides the environmental specifications for the Cisco 4-Gbps CWDM SFP transceivers.
Table B-33 provides the optical specifications for Cisco 4-Gbps CWDM SFP transceivers.
Note • In typical point-to-point deployments, all wavelengths have a minimum reach of 24.8 miles (40 km).
• Parameters are specified over temperature and at end of life unless otherwise noted.
• When shorter distances of single-mode fiber are used, it is necessary to insert an in-line optical
attenuator in the link to avoid overloading the receiver.
• A maximum of 24 4-Gbps CWDM SFPs are supported in a single MDS switching module.
