TEST POINTS and ADJUSTMENTS

The OTPN-400C receiver has an external test point to monitor optical signal level.
The received power test point is calibrated at 1V per mW @ 1310nm. Internally,
there is a jumper used to select wavelengths between 1310nm and 1550nm. The
factory presets the jumper to 1310nm.
