Device by which bistable light switch realizes monostable function

Abstract

An apparatus for a bistable optical switch to achieve monostable-function, comprising a power supply unit, a detection circuit unit, a control unit, a latch, an optical switch drive circuit unit, an energy storage unit and a bistable optical switch. The present invention solves the problem in the prior art that bistable switches cannot achieve monostable switch-function, allowing the current networks to complete various types of protection according to the different requirements of customer operations and accommodating various applications of network protection.

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...

Problems solved by technology

How to use the same optical switch to realize both the bistable function and the monostable function is a problem that cannot be solved by the current technical solutions, which brings a lot of work and cost to network planning and maintenance.
