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).

The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on. 1. Remove and keep the SC port’s rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics. 2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber 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 SC port on the switch and the other end to the SC port on the other device. Since SC connectors are keyed, the cable can be attached in only one orientation.

As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. Note: If you use the optional SC-ST Converter, be sure to connect the converter’s Tx (Rx) port to the Rx (Tx) port on the other device. 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control. 100BASE-FX connections operate at 100 Mbps, full duplex, with auto-negotiation of flow control.
