Clean the optic Fiber end-face, and connect with the PIN port on the instrument (SC/

FC/ST adaptor), noted with the type of the optic fiber adaptor, the non-matched

connecting will make the damage of the connector on the instrument and also make

the faulty of the measurement result.

E.g.: 1310nm measurement, after connect with the optic fiber, it will displaying

-20dBm, press

, set the -20dBm as the reference value, and it will also display

relative value (dB), see as following:

In order to get the loss between the two measurements, do another time

testing under the first relative output power. The relative value will be calculated

automatically. For example the second time testing of 1310nm output power is

-35dBm, the relative output power will be -15dBm. (relative output power=absolute

output power-reference value -15dBm=-35.00dBm- (-20.00dBm) see as following:

Button in this case, is to choose the wavelength. Take 1310nm
