Abstract

The embodiment of the invention discloses a switching method and device of an OLP transmission link of an optical fiber automatic switching protection system, a storage medium and an OLP. The method is used for at least one OLP in at least two OLPs connected in a cascading mode, and the OLP comprises a first input end used for receiving a first signal and a second input end used for receiving a second signal. The method includes: obtaining first time information in which signal values of the first signal and the second signal are both smaller than respective first threshold values; obtaining afirst signal value of the first signal and a second signal value of the second signal within the period from the first time to the second time; and after a third time, at least obtaining a third signal value of the first signal, and determining whether to switch the OLP from a first transmission link to a second transmission link according to the first signal value, the second signal value and the third signal value.

Description

technical field [0001] The present invention relates to an optical fiber automatic switching protection system (Optical Fiber Line Auto Switch Protection Equipment, OLP for short) technology, in particular to a switching method, device, storage medium and OLP of an OLP transmission link. Background technique [0002] As a system on the optical cable link, OLP has the characteristics of independent and transparent data transmission, high security, and fast fault recovery. It can cooperate with other equipment or devices in the optical network to build a non-blocking, high-reliability , safe, flexible, and disaster-resistant optical communication network system. [0003] OLP has two kinds of transmission links, active link and standby link. The OLP can use at least one of the two transmission links to transmit optical signals. The switching protection mode of OLP includes 1+1 protection mode and 1:1 protection mode. Because the OLP switching speed of 1+1 protection mode is f...
