MT-RJ Fiber Connections
Each device requires a 62.5/125 micron or 50/125 micron multimode
fiber optic cable with MT-RJ connectors at both ends.
1. Remove and keep the MT-RJ port's plastic cover. When not connected
to a fiber cable, the cover should be replaced to protect the optics.
2. Check that the fiber terminators are clean. You can clean the cable
plugs using an appropriate MT-RJ cleaning kit. Dirty fiber terminators
on fiber optic cables will impair the quality of the light transmitted
through the cable and lead to degraded performance on the port.
3. Connect one end of the cable to the MT-RJ port on the switch and the
other end to the MT-RJ port on the other device. Since MT-RJ
connectors are keyed, the cable can be attached in only one
orientation.
4. As each connection is made, check the Link LED on the switch's front
panel for the corresponding port to be sure that the connection is
valid.
You can run a fiber link up to 2 km (1.24 mi.) in full-duplex mode, and
412 m (1351 ft.) in half-duplex mode. However, note that power budget
and timing constraints must also be considered when calculating the
maximum cable length for your specific environment.
