DataNET Fiber Optic Connections, Continued
The DataNET Fiber Optic Couplers use ST-style connectors (twist &
lock). Always insure that the TX (Transmit) on one end of the link is
connected to the RX (Receive) at the other end of the link. Some duplex
fiber optic cables are coded to help monitor the direction of data travel. If
the fibers are not coded, special attention must be paid to insure a
proper connection.
