Devices

An optional slide-in 1000BASE-SX, 1000BASE-LX or 100BASE-FX module, or
1000BASE-X transceiver may be used for backbone and long distance connections,
or for ISP (Internet) connections. A 1000BASE-SX, 100BASE-LX or 1000BASE-X
transceiver may also be used for connecting to a high-speed server.

MT-RJ Connections

Each single-mode device requires a 9/125 micron multimode fiber optic cable with
MT-RJ connectors at both ends. Each multimode 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. 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

SC Connections

Each single-imode fiber optic port requires 9/125 micron multimode fiber optic
cabling with an SC connector at both ends. Each multimode fiber optic port requires
50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at
both ends. If you need to connect to a device with 62.5/125 micron cable that has
ST-type connectors, Accton provides an optional SC-ST Converter (Part Number:
ST5002).
