The invention provides a method for light path protection seamless switching and a light path protective device. The method comprises the steps that: output light of a light switch in a light path guide plate is connected to a light-gathering device; the light of the light-gathering device is connected to a light opening; before the light switch completes the light path switch, the light-gathering device receives and outputs a light signal input through the light opening. The method and the light path protective device can guarantee uninterrupted signals in the process of light path switch aspossible so that a network can stably operate.
Description
Method for seamless switching of light path protection and light path protection device Technical field The present invention relates to the technical field of optical network communication, in particular to a method for seamless switching of light path protection and a light path protection device. Background technique The optical path protection board (Optic Protection Modular, OPM) is a passive device that is used for traffic replication and realizes the blocking function of a secure router. When the security router fails, the optical path protection board can bypass the service traffic passing the faulty device, thereby realizing the protection function for the service traffic. Figure 1 is a schematic diagram of the connection of the optical path protection board. As shown in Figure 1, there are six ports on the optical path protection board, P1, P1', P2, P2', P3 and P4, among which: P1: Two-way sending and receiving, connected to external router A; P2: Two-way sending ...
