Input/Output Impedance, VSWR:

50W, VSWR < 1.5 : 1 (14dB min.)

 

Transmitter Alarm Output:

Monitors laser back‐monitor photocurrent and laser diode forward current. Open collector alarm is raised when laser health is degraded.

 

Receiver Alarm Output:

Monitors received light level. Open collector alarm is raised when optical loss reaches 20dB.

 

Open Collector Alarm Rating:

+15V max. 500mA max.

 

Transmitter Monitor Output:

Analogue measurement of laser diode forward current (IFL). This analogue output voltage monitors the efficiency of the laser diode. VIFL = 68 x I fwd (A).

 

Receiver Monitor Output:

Analogue measurement of received light level (RLL). The VRLL is set to give +7.75V when link gain is +9dB=, and varies by 0.125V/dB of RF link gain when the gain is reduced by optical path losses.
