sfp modules
the catalyst 3560 switch uses gigabit ethernet sfp modules to establish fiber-optic and 1000base-t connections. these transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an sfp module slot. you can use the sfp modules for gigabit uplink connections to other switches. you use fiber-optic cables with lc or mt-rj connectors to connect to a fiber-optic sfp module. you use category 5 cable with rj-45 connectors to connect to a copper sfp module.
the catalyst 3560 models support these cisco sfp modules:
1 1000base-lx
2 1000base-sx
3 1000base-zx
4 1000base-t
5 100base-fx
6 cwdm
for more information about these sfp modules, see your sfp module documentation.
sfp module patch cable
the catalyst 3560 switch supports the sfp module patch cable, a 1/2 meter, copper, passive cable with sfp module connectors at each end (see figure 1-9). the patch cable can connect two catalyst 3560 switches in a cascaded configuration.
see “inserting and removing the sfp module patch cable” section for more information about using the sfp module patch cable.
