Configuring PRBS Test

Some OTUs of the OptiX OSN 8800 T32(NA)/OptiX OSN 8800 T64(NA)/6800A/3800A provide the pseudo random bit sequence (PRBS) error detection function. 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.

• Application of PRBS
  Specific application scenarios are provided to meet different requirements of the PRBS test.
• Configuring the PRBS Test Status of the Auxiliary Board
  Before you configure a PRBS test on the meter board, set PRBS Through of the auxiliary boards at the near and far ends.
• Configuring PRBS Test on the Meter Board
  In the PRBS test, the OTU sends out the PRBS code and monitors the PRBS code that is looped back from the remote board. After comparing the PRBS code that is sent with the code that is received, you can determine that the current link or equipment is normal or not.
