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.

• Application of PRBS
  Specific application scenarios are provided to meet different requirements of the PRBS test.
• Configuring the PRBS Test Status of the Tested Board
  Before you performing the PRBS test, configure the PRBS Test Status of the tested boards.
• Performing the PRBS Test of the Test Board
  The PRBS test is realized by that the OTU sends the PRBS code and monitors the PRBS code looped back from the local board or remote board. By comparing the PRBS code sent with the PRBS code looped back, the OTU can determine whether the current link or equipment is normal.
