Abstract

The invention relates to the communication transmission field, especially discloses a device by which a bistable light switch realizes a monostable function, characterized by comprising a power supply unit, a detection circuit unit, a controlling unit, a latch, a light switch drive circuit unit, an energy storing unit and the bistable light switch. By using the invention, the problem that the prior art can not use the bistable light switch to realize the monostable function is solved, so that the conventional network can finish protections of different types according to the different demandsof client businesses to thereby satisfy the applications of various network protections.

Description

technical field [0001] The invention relates to the field of communication transmission, in particular to a device for realizing a monostable function by a bistable optical switch. Background technique [0002] In the field of optical communication, an optical switch is commonly used to implement a network protection switching function. When the main path is abnormal, the service is switched to the backup path by controlling the optical switch, so as to ensure the normal use of network services. There are currently two types of optical switches, monostable optical switches and bistable optical switches. The working principle of the monostable optical switch is that when the power supply of the optical switch is cut off, the state of the optical switch is always switched to the default channel, such as the standby channel. The working principle of the bistable optical switch is that when the power supply of the optical switch is cut off, the state of the optical switch stay...
