The 100BASE-FX and 1000BASE-SX ports use MT-RJ connectors, shown in Figure B-4. 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 3-1. Use the Cisco part numbers in Table 3-1 to order the patch cables that you need.
