The 100BASE-FX and 1000BASE-SX ports use MT-RJ connectors, shown in
Figure B-3. These ports use 50/125- or 62.5/125-micron multimode fiber-optic
cabling.
You can connect a 100BASE-FX or 1000BASE-SX port to an SC or ST port on a
target device by using one of the MT-RJ fiber-optic patch cables listed in
Table B-1. Use the Cisco part numbers in
you need.
