To ensure that the transmission equipment can be normally running for long, you need to periodically maintain the transmission equipment or perform some simple operations of troubleshooting on existing problems.
Querying Optical Power of a Board
The optical power of a signal changes after it is transmitted. This change affects intensity and sensitivity of the signal. If the optical power is too high or too low, damage to optical components or bit errors may be caused, affecting the service. Querying optical power is a common maintenance method.
Resetting Boards
You can reset a board by using the U2000 Web LCT by following the instructions below.
Configuring PRBS on a WDM Network
Some OTUs of the , provide the pseudo random bit sequence (PRBS) error detection function. On the U2000 Web LCT, the meter board can be configured to send PRBS signals, and the client side and WDM side of the auxiliary board to transparently transmit the PRBS signals. In this way, you can perform the bit error test of the transmission link without attaching a meter to the equipment during the deployment. Submarine side and NPE side of the auxiliary board to transparently transmit the PRBS signals. In this way, you can perform the bit error test of the transmission link without attaching a meter to the equipment during the deployment.
