Problems solved by technology

In general, the optical power of the optical control signal is relatively large, which can easily affect or even damage the OTDR. Therefore, during the switching process of the optical channel, try to avoid switching the optical path passing through the channel of the optical control signal.

[0004] The current existing solution is to calculate the coordinates of the channel points that need to be switched by the MEMS optical switch, and obtain the required hitless points through the angle and distance of the surrounding channels, so as to avoid the channel points in the middle of the channel path to be switched. The advantage is that it avoids interference to other channels to a certain extent, but the disadvantage is that when the channel environment is more complex, it takes too long to calculate hitless points in this way, and it may even be impossible to calculate hitless points that can avoid interference with other channels Case
