Fix the jumpers and connectors needed to connect the fiber to be
tested between the source output and the power meter input.
2
In the set-up menu, select dB units.
3
The power displayed in the Power Meter window corresponds to the
optical loss of the link tested. It can be displayed in the table (see
It is important to set the zero of the power meter before making any
measurements where accuracy is required, as the noise from the ger-
manium photodiode fluctuates over time and with variations in tem-
perature.
