Integrated light attenuation device

Abstract

The invention relates to the light attenuation device and particularly relates to an integrated light attenuation device. The integrated light attenuation device comprises a first light splitter, a second light splitter, a first optical power monitoring device and a second optical power monitoring device. An optical signal emitted by an input optical fiber goes through a first light splitter. Partof optical signals are reflected to the first optical power monitoring device through the first light splitter . An optical signal emitted by an optical attenuation mechanism goes through the secondlight splitter. Part of optical signals which go into an output optical fiber are reflected into the second optical power monitor through the second light splitter. The invention designs an integratedlight attenuation device in which optical power monitoring devices are arranged. The integrated light attenuation device does not need to adopt extra optical power monitoring devices, reduces the volume occupying spaces, simplifies external wire connection, makes product integrated, improves stability, reduces production cost and improves integral performance.

Description

technical field [0001] The invention relates to the field of optical attenuators, in particular to an integrated optical attenuation device. Background technique [0002] The optical attenuator is a device used to attenuate the optical power. It is mainly used in the index measurement of the optical fiber system, the signal attenuation of the short-distance communication system and the system test and other occasions. [0003] Optical attenuator is a very important fiber optic passive device. It can attenuate the optical signal energy according to the user's requirements. It is often used to absorb or reflect the optical power margin, evaluate the loss of the system and various tests. . At present, serialized optical attenuators have been widely used in the field of optical communication, bringing convenience to users. [0004] Generally speaking, optical attenuators can be divided into fixed attenuators, graded adjustable attenuators, continuously adjustable attenuators, ...
