OLP protection implemented by TN11OLP01 or TN12OLP01

1

OLP can be classified into OTS OLP protection and OMS OLP protection. Whether TN11OLP01 or TN12OLP01 boards can be used to form OLP depends on the input optical power values of optical ports RI1 and RI2 on OLP boards.
If the input optical power values of both optical ports RI1 and RI2 on OLP boards do not exceed 7 dBm, TN11OLP01 or TN12OLP01 boards can be used to form OTS OLP protection.
In the OMS OLP protection scenario, the input optical power values of optical ports RI1 and RI2 are prone to exceed the maximum optical power (+7 dBm) of the TN11OLP01 and TN11OLP02 boards. Therefore, TN11OLP01 or TN12OLP01 boards cannot be used in this scenario.

Principle and implementation mode of the OLP protection
The OLP protection uses the dual feeding and selective receiving function of the OLP boards and uses separate fibers for working and protection trails between adjacent sites to protect signals on the line.

Whether TN12OLP03 boards can implement OLP protection in the OSN 6800
TN12OLP03 boards support single-mode optical fibers and mainly apply to scenarios with large optical power values. The TN12OLP03 boards support client 1+1 protection, intra-board 1+1 protection, and OLP protection.

WTR period of OLP protection
The OLP board supports optical line protection, intra-board 1+1 protection, and client 1+1 protection. If the reversion mode is revertive, the default WTR period is 10 minutes.

WTR time of OLP protection
The OLP board supports optical line protection, intra-board 1+1 protection, and client 1+1 protection. If the reversion mode is revertive, the default WTR period is 10 minutes.

Whether the working and protection channels must be fixed when the OLP board is used to configure OLP protection
When the OLP board is used to configure OLP protection, the working channel must be the optical port 1 (RI1/TO1) of the OLP board and the protection channel must be set to optical port 2 (RI2/TO2). Otherwise, the OLP protection group cannot work normally.
