Cisco Cisco DWDM Transceiver Modules 安装指南

 lists the fiber-optic cabling specifications for the SFP modules that you 

install in the converter module. Each port must match the wavelength 
specifications on the other end of the cable, and the cable must not exceed the 
stipulated cable length. The SFP modules using fiber-optic connections need 
fiber-optic cables with LC/PC or LC/UPC connectors. The SFP modules using 
copper connections need Category 5E cables with RJ-45 connectors. Copper 1000 
BASE-T SFP modules use standard four twisted pair category 5E cable at lengths 
up to 328 feet (100 meters).

cable with SFP module connectors at each end. The patch cable can connect two Catalyst 3560-E 
switches in a cascaded configuration.
