In MSP networking, when optical fibers are connected between sites, the east optical board of a site is connected to the west optical board of the dow

Dear friend!

Based on the direction of services on the ring, self-healing rings can be divided into unidirectional rings and bidirectional rings.

1. In the case of a unidirectional ring, the routes for transmitting and receiving services are different when the network is normal. The services With diverse routes are called unidirectional services.

2. In the case of a bidirectional ring, the routes for transmitting and receiving Services are consistent and are called uniform routes. The services with uniform routes are called bidirectional services. The most commonly used are two-fiber bidirectional MSP ring: 

On an MSTP network, for the two-fiber bidirectional MSP ring (MSP ring), when optical fibers are connected between stations, the east optical board of the station is connected to the west optical board of the downstream station. These stations are connected in turn in a ring. In this case, the first half of each fiber is the working channel, and the second half of each fiber is the protection channel for transmitting services to the opposite direction.

Your description is not consistent with how both MSP rings work, so it is false.

Thank you！
