Abstract

The invention discloses a special 2M optical interface multiplexing protection channel and an application method. One side of a 2M optical interface board is provided with a light receiving module anda light emitting module, and the other side is provided with an LC type optical fiber jack; the 2M optical interface board is fixedly arranged on SDH optical transmission equipment; a relay protection professional protection device is directly connected with the light receiving module and the light emitting module on one side of the 2M optical interface board through a tail cable; and the SDH optical transmission equipment is plugged into the LC type optical fiber jack in the other side of the 2M optical interface board through a LC type optical fiber plug. The special 2M optical interface multiplexing protection channel has the advantages of realizing unified encapsulation of 2M optical signals, realizing direct connection, enhancing the channel reliability, saving investment, and makinga professional operation and maintenance interface clearer. A 2M optical interface protection channel mode is adopted, so that the flexibility in ensuring a service channel between power substationsis enhanced. The special 2M optical interface multiplexing protection channel is suitable for power optimization, new construction, emergency support and other application scenarios.

Description

Technical field [0001] The present invention relates to the technical field of relay protection information for electric power, and more specifically to the technical field of multiplexed protection channels for power dedicated 2M optical interfaces. Background technique [0002] There are two types of optical fiber communication channels that transmit relay protection information: dedicated channels and multiplexed channels. The 2Mbps multiplexed protection channel occupies less fiber core resources, has unlimited transmission distance, flexible operation mode adjustment, and supports remote monitoring. It is generally widely used as a circuit protection channel. However, 2M optical / electrical conversion equipment is required for information conversion between the protection device under this channel and the SDH optical transmission equipment. This results in the lack of a unified interface standard for this application method. The protection devices and conversion devices betwe...

Problems solved by technology

However, 2M optical / electrical conversion equipment is required for information conversion between the protection device and SDH optical transmission equipment under this channel, resulting in the lack of a unified interface standard for this application method, and the protection devices and conversion devices of different manufacturers cannot be used for each other. Technical barriers, engineering implementation is complicated, maintainability is poor, and investment is large. Due to engineering complexity, the stability and reliability of information protection channels are low
