Light protection switch unit with 3R amplifying function

Abstract

The invention discloses a light protection switch unit with a 3R amplifying function, and the light protection switch unit with the 3R amplifying function comprises a light power amplifying module, a light power monitoring module and a light way automatic protection module. The light power amplifying module conducts 3R regeneration amplification and graining on a received light 10G / 2.5G signal, small part of light power of the amplified signal enters the light power monitoring module to obtain an on-line monitored light power result, most light power of the amplified signal enters the light way automatic protection module, meanwhile, the light power monitoring module transfers the on-line monitored light power result to the light way automatic protection module, the light way automatic protection module selects an proper optical fiber to transfer the most light power, and finally most light power are output from the light way automatic protection module. The light protection switch unit with the 3R amplifying function is simple in structure, convenient to use, guarantees non-blocking of communication service by automatically switching the transfer optical fiber, achieves 3R amplification of light through the light power amplification module, and offsets big insertion loss when light is switched.

Description

[0001] technical field [0002] The invention relates to the field of optical fiber protection equipment, in particular to an optical protection switching unit with a 3R amplification function. Background technique [0003] At present, only a few foreign companies have the ability to research and produce optical fiber protection equipment, mainly JDS, E-TEK, Dicon, etc., and they do not have the function of 3R amplification of the optical path; the use of the product is affected by the insertion loss. With the rapid development of optical communication technology, especially the development of all-optical communication network technology, the demand for optical fiber protection equipment (including domestic demand) will increase rapidly. The development of optical fiber protection equipment with amplification function is of great significance for reducing the cost of network node construction and upgrading, and improving network operation reliability and security survivabili...
