Test setup
The following figure illustrates a possible test setup. The number and type of optical
interfaces used depends on the customer configuration.
Procedure
Proceed as follows to check the mean launched power:
.................................................................................................................................................................................................
1
Clean the output port to be tested (see appendix A,
.................................................................................................................................................................................................
2
Connect the optical power meter to that port.
.................................................................................................................................................................................................

CAUTION
Destruction of the power meter caused by a too high input power.
Connecting the optical power meter with a transmit power exceeding the maximum
power limit, will cause the destruction of the power meter, as the input power is then
too high.
The supported maximum optical power limit of the optical power meter must be
greater than the maximum mean launched power of the measured optical circuit pack
to avoid damage.
Measure the mean launched power at the connected port and enter the measured value
in the table provided in chapter 9.
