Huawei OptiX OSN 6800 V100R004C02: Optical Power Commissioning Procedures
Generally,
the portion between two OTMs in the OptiX WDM system is considered as one network
segment. One network segment has two signal flow directions, namely the
transmit direction and the receive direction.
In
the case of an Huawei Transmission OptiX WDM system, the optical power of a network segment is
commissioned on a per-NE basis according to the signal flow.
First,
commission the transmit optical power of one OTM. Then, commission the optical
power of each downstream NE along the transmit direction, and finally
commission the receive optical power of the destination OTM. After
commissioning the optical along the transmit direction, commission the optical
power in the reverse direction of the system.
Project
X is considered as an example to describe how to commission the optical power
of an OptiX WDM system.
Figure 1 shows the networking diagram of Project X.
Project
X consists of two network segments: A-B-C and A-F-E-D-C.
First,
commission the optical power on the A-B-C network segment according to the
following sequence.
Commission the optical power along the
A-B-C signal flow:
– At ONE A, commission the optical power to
ONE B.
– At ONE B, commission the optical power
from ONE A.
– At ONE B, commission the optical power to
ONE C.
– At ONE C, commission the optical power
from ONE B.
Commission the optical power along the
C-B-A signal flow:
– At ONE C, commission the optical power to
ONE B.
– At ONE B, commission the optical power
from ONE C.
– At ONE B, commission the optical power to
ONE A.
–
At ONE
A, commission the optical power from ONE B.
Then
see the previous procedures to commission the optical power of the A-F-E-D-C
network segment in two directions.
