Method used to enable the laser of an OAU or OBU board

All series of OAU and OBU boards can function as wide-spectrum light sources during deployment commissioning. Therefore, you need to learn the commands used to forcibly enable the lasers on the boards.
1. The commands used to forcibly enable the lasers on all series of OAU and OBU boards are the same. You can run a command on the Navigator or run a PTP command to enable the lasers. The former method cannot be used in some versions.
2. Command line settings
Run the :cfg-set-oaworkmode command to forcibly enable the lasers on the boards.
The command format is as follows: :cfg-set-oaworkmode:

  • Bid
  • ,
  • Port
  • ,
  • Path
  • ,
  • Mode
  • ,
  • Password
  • ;
  • Mode
  • indicates the board enable status and can be set to gainlock or powerlock, corresponding to the gain-locking mode and power-locking mode respectively.
  • Password
  • indicates the verification password used to enable a laser. The default value is dange.
    c. When a laser is forced to emit light, the output optical power of the optical amplifier board is always 10 dBm.
    d. This function is supported by or later NE software versions.
    3. PTP command settings
    The command is as follows:
    In the preceding command, 17 and 08 are command words, c1 and 1c are check bytes, 1 indicates secure working mode while 0 indicates normal working mode (However, the digit here must be set to 1.), and the last 4 bytes indicate the target optical power parameter (a value 10 times the actual optical power). When the optical power is a negative value, the value is expressed as two's complement. For example, the output optical power is 6 dBm by running the :nptp:bid,17,08,c1,1c,1,0,0,0,3c; command, and the output optical power is �?0 dBm by running the :nptp:bid,17,08,c1,1c,1,ff,ff,ff,9c; command. In the later command, the negative optical power value is expressed as complements.
