Fiber optic attenuators controllably attenuate optical signals according to user needs.
Mainly used in the evaluation, research, adjustment and correction of optical communication line systems.
Now Changguang Communications will explain to you the classification of fiber optic attenuators.
1. Online Fiber optic attenuator
Online optical fiber attenuator is an optical communication device that provides specific attenuation according to the different needs of different projects.
Online optical fiber attenuators can be used in various optical fiber transmission lines to attenuate preset light intensity.
This kind of optical fiber attenuator is mainly used in optical fiber communication networks, optical fiber CATV networks, optical fiber data networks and optical fiber test systems.
The attenuation of online optical fiber attenuatorIt has high attenuation accuracy, low additional loss and better stability than other types. At the same time, its attenuation value can be adjusted according to your own needs.
2. Yin and Yang type optical fiber attenuator
This fiber attenuation The attenuator is a male-female device, which is the same as the fixed fiber attenuator. It also supports a variety of connector methods such as LC, SC, FC and ST.
Yin and yang type optical fiber attenuators are ground using PC, UPC or APC, with an attenuation value of 1-30dB.
It uses metal ion-doped attenuating fiber technology to achieve the attenuation effect. It has the advantages of light weight, high precision, multiple forms, easy use, small size and light-resistant power light source.
Mainly used in: optical distribution frames, optical fiber network systems, high-speed optical fiber transmission systems, cable television (CATV) systems, long-distance trunk dense wavelength division multiplexing (DWDM) systems, optical add-drop multiplexers (OADM).
3. Fixed fiber optic attenuator
The fixed fiber optic attenuator looks more like an adapter. It is mainly used in fiber optic communication systems, fiber optic CATV and high-power optical device measurements.
It is mainly used through flanges, and jumpers with various connectors of FC, SC, ST and LC can be used. It is very convenient to install and easy to use, and is loved by many users.
