Optical Head Analog Output

46
Do not apply an external voltage to this connector.
The analog output is the BNC connector on the back of the optical head.
It outputs a voltage directly proportional to the strength of the optical
signal at the optical input in the current range. The analog voltage is
always in the range between 0 and 2 V. For linear output, 1 V corresponds
to the nominal value of the current range (like 100 µW in the -10 dBm
range) and 0 V corresponds to zero signal. Do not apply an external
voltage to this connector.
