Setup
1. Ensure both fiber interfaces are installed and powered up. Ensure that the TX connector on the near
interface is connected to the RX connector on the far interface and vise-versa.
2. Transmit levels are set by the GAIN SELECT jumper on the PCBA. The XMIT and LIMIT LEDs are
used to indicate the optimum setting.
3. Move the GAIN SELECT jumper to the highest position that will keep the green XMIT LED on, but
will not turn on the orange LIMIT LED.
4. Repeat for both fiber interfaces.
