SYNC/ASYNC FIBER OPTIC MODEM
Connecting the Fiber Optic Cables
Two fiber optic ST connectors are located on the rear panel and marked TX and
RX.
1. Remove the protective caps from the connectors and store them in a safe
place for later use.
2. Connect the transmit fiber to the connector marked TX and the receive fiber
to the connector marked RX.
3. At the remote unit, connect the transmit fiber to RX and the receive fiber to
TX.
Connecting the DTE
NOTE
We recommend using a shielded twisted-pair cable between the Fiber
Optic Modem and the DTE (mainly for higher frequencies). The line
receivers in the Fiber Optic Modem are 100-ohm terminated.
• Press the end of the connector into the DTE interface connection on the Fiber
Optic Modem.
For more information on the RS-530 DTE interface, see
Appendices A
and
B
.
If problems arise when connecting to the DTE interface, first check that the
DTE interface is properly terminated.
