ONNECTOR INSERTION LOSS TESTING
To ensure the accuracy of measurement, optical connectors should be kept clean.
In the process of measurement, please always avoid looking directly into open
optic fiber, optical output, optical connectors or other laser source, for it might
cause eye injuries.
Only under the dBm mode, reference power value can be set.
5.2 Link Loss Testing
For link loss testing, a stabilized laser source and an accurate optical power meter are
needed to measure the attenuation of a single-mode or multimode link.
Please follow the following procedures:
1.
If users want to make full use of the measurement function of the instruments(laser
source and power meter), then test of the output power of laser source connected to optical
jumper cable must be performed before link testing. And connect laser source and power
meter with tested optical jumper cable, as in Figure20. Power value is noted as P1.
