Commissioning Guidelines
Basic requirements
DWDM system:
The optical power should be between the allowable maximum and
minimum values.
Ensure that the power fluctuation within a range.
Meet the requirement of system expansion.
CWDM system:
Only the received optical power of the OTU is needed in optical power
commissioning.

General commissioning consequence
It consists of two network segments: ABC and AFEDC. Commission the optical power in A>B>C signal flow:
Station A: A-to-B transmit direction Station B: A-to-B receive direction
Station B: B-to-C transmit direction Station C: B-to-C receive direction
Commission the optical power in C>B>A, A>F>E>D>C, C>D>E>F>A.

Commissioning Optical Power of OTU
1. Forcing the OTU board to emit light
The WDM side of the OTU board is forced to emit light by default.
2. Adjusting the input optical power of OTU board
Optimal receive power range: (sensitivity+3)~(overload-5)dBm
Case: For a certain OTU, overload = 0dBm, receiver sensitivity = -16dBm, the receive optical power range is 1.
Note the overload of the APD receiver laser is only -9dBm.

Commissioning Optical Power of Multiplexer and Demultiplexer Commissioning requirements
Adjust the attenuation of the VOAs of the M40V/D40V to 5dB before
commissioning.
Adjust the VOAs to make the optical power (or OSNR) closer to the
average value.
Ensure that the maximum difference of optical power among all the
channels is within 4dB and that of OSNR is within 2dB.
-
Copyright 2009 Huawei Technologies Co., Ltd. All rights reserved. Page26
Commissioning Optical Power of EDFA
1. Adjusting the input optical power of OA board
Adjust the average single wavelength input optical power of the IN
interface of the OA and make it close to the typical input power of
single wavelength.
2. Adjusting the gains of OAU1
Set the gain to ensure that the mean output optical power equals the
maximum output optical power of single wavelength.

If the average single wavelength input optical power is lower than the
typical input power of single wavelength, no VOA is needed.

On-off gain is not less than 10dB.
On-off gain = Optical power on the SYS interface when the laser is enabled
Optical power on the SYS interface when the Raman laser is disabled
Special LSH/APC fiber connector.
The laser is by default turned off after the Raman amplifier is powered
on.

Commissioning Optical Power of OSC
Commissioning Requirements
Basic requirements of the optical power commissioning on the OSC
are as follows:
The received optical power of the OSC: 45dBm ~ 8dBm.
A 15dB fixed attenuator is required at the receive end of the OSC in the
