The invention belongs to the technical field of redundant link protection of optical communication equipment, and discloses a method for realizing redundant link protection function for a controllableoptical port. When power supply for a communication circuit is regular, an external optical path signal enters into an optical switch and arrives one optical module through one optical interface, enters an IC to be subjected to data processing, the IC processes data and transmits the data to the other optical module, the other optical module transmits the processed data to the other optical interface through the optical switch, thus, the communication circuit can communicate with the outside; and when power supply for the communication circuit is abnormal, a redundant link protection controlsignal is input to the optical switch, a connection link between the optical and the optical module is cut off, and the two optical interfaces are connected directly, thus, after passing through one optical interface, an external optical path signal is directly transmitted to the other optical interface instead of entering into the IC of the communication circuit to be subjected to data processing, and the other optical interface communicates with the outside. The method realizes that, when the equipment is failed, the failed equipment is automatically skipped, thus, communication of the wholesystem can be recovered.
Description
technical field [0001] The invention belongs to the technical field of redundant link protection of optical communication equipment, and in particular relates to a method for realizing the redundant link protection function of a controllable optical port. Background technique [0002] At this stage, communication systems have a variety of transmission media, which are mainly divided into electrical signal transmission and optical fiber transmission. The electrical signal transmission medium is suitable for short-distance, low-bandwidth, and low-cost communication systems, and optical fiber transmission is usually used for high-bandwidth and long-distance applications. With the complication and high speed of the communication network, optical fiber communication has the advantages of low loss, high capacity, and does not require too many repeaters. It is widely used in the communication network, and the network communication technology has been developed rapidly. Transmissio...
