2. The Catalyst 3560-E switch supports the SFP module patch cable, a 0-5-meter, copper, passive
cable with SFP module connectors at each end. The patch cable can connect two Catalyst 3560-E
switches in a cascaded configuration.
Table 2 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).
