DC POWERING AND INDICATORS
The unit operates with the OTPS-12A AC/DC power supply. The typical current requirements
for the receiver with that power supply is 150mA. The current draw for other voltages is as
follows:
Input Voltage 10V
DC
12V
DC
15V
DC
Rx Current
200mA 150mA 120mA
An LED indicator is provided for easy setup and maintenance. The tri-color indicator LED is
yellow when the optical input is too low, red when the optical input is too high and is green
when the optical input is in the usable range. This range is approximately -15dBm to +3dBm.
for the PIN detector style receiver. The levels vary widely with the APD option receivers.
