Principles for configuring the OBU1P1 boards in the PID system for OptiX OSN 8800

When TN55NPO2 boards comprise a 120G PID group, OBU1P1 boards need to be configured based on the line loss if the transmission distance is less than 40 km. If the line loss is less than or equal to 11 dB, no OBU1P1 board needs to be configured. OBU1P1 boards need to be configured at the receive site when the line loss is greater than 11 dB but less than or equal to 20 dB. When the transmission distance is greater than 40 km but less than 80 km, OBU1P1 boards need to be configured at the receive site when the line loss is greater than 9 dB but less than or equal to 20 dB.
