Port Connections

Fiber-Optic Port

To connect the duplex fiber-optic cable to the hub, attach one of the two fibers between the

hub’s “transmit” port (labeled “Tx”) and the “receive” port of the other device, such as a

transceiver. Attach the other fiber between the hub’s matching receive port (labeled “Rx”) and

the transmit port of the other device.

If one fiber on this end of the cable is marked, such as with a white sleeve, attach it to the hub’s

Tx port. Attach the unmarked fiber to the hub’s Rx port. Use the same convention at the other

end of the cable. (At the other end, the marker is on the other fiber.)

For detailed instructions on attaching ST connectors, see the next page.

Caution The bend radius of the fiber-optic cable must be 50 mm (2 inches) or

greater. Do not wrap the cable around sharp edges. The cable must be free

of kinks, twists, and jacket irregularities. Cable connectors and hub

receptacles that are not in use should be covered with dust covers.
