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.

135km/39dB 85km/27dB

80km/26dB 100km/30dB

55km/15dB 60km/16dB

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.


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.



Commissioning requirements of OA (40-channel)

Ptotal = Psingle + 10 x lgN (N: max. number of s) Case: OBU103, 20dBm = dBm + 10 x lg40.

Case: OAU101, typical input/output power for each channel: -16/+4dBm, the signal gain range: 20 ~ 31dB

If the average single wavelength input optical power is lower than the

typical input power of single wavelength, no VOA is needed.

Change the gain of OAU101 to dB by NMS.

Commissioning Optical Power of Raman Amplifier Commissioning requirements

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.

Fiber should have no connector within the distance of 0~20km.


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

station.

Backing Up NE Database

After the configuration data is delivered, it is required to backup

the NE database.

The NE database can ensure that the SCC board restores to

normal operation automatically upon data loss or power failure.


Questions

What are the general commissioning procedures of OptiX OSN

3800/6800/8800?

If the input power of single wavelength is -16dBm, whats the

value of input power for 40 wavelengths?
