The 100BASE-FX and 1000BASE-SX ports both use 50/125- or 62.5/125-micron
multimode fiber-optic cabling. The 100BASE-FX ports operate only at 100 Mbps
in full-duplex mode, and the 1000BASE-SX ports operate only at 1000 Mbps in
full-duplex mode.
In full-duplex mode, the cable length from a switch to an attached device cannot
exceed 1804 feet (550 meters).
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 1-1. Use the Cisco part numbers in
you need.
