	15.5 miles (25 km)
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.

•When interoperating a Cisco 4-Gbps CWDM SFP transceiver with a Cisco 1/2-Gbps CWDM transceiver, the speed of ports on the Cisco 4-Gbps CWDM SFP transceiver must be manually configured to 1-Gbps or 2-Gbps.
