The optical attenuator is close devices commonly used in a variety of fiber optic transmission lines and fiber optic sensors and optical test instruments which provide different attenuation. With the acceleration of the process of continuous development of IT and information technology, optical fiber and optical components used more widely, such as optical fiber communication systems, fiber optic data network, fiber CATV. In recent years, the introduction of the "fiber to the office", “fiber to the home” will give the optical fiber and optical components to create a broader market, including optical attenuator increasing demand.
Optical attenuator in accordance with if the attenuation value is fixed, can be divided into two kinds of fixed and adjustable. Fixed attenuator is divided into Flange type, yin and yang outlet line fixed and online fixed, adjustable attenuator is divided into mechanical adjustable line adjustable , Online Adjustable and digital display Adjustable.
1)Flange type optical attenuator
2)Yin and Yang socket type optical attenuator
3)Online fixed optical attenuator
4)Mechanical adjustable optical attenuator |
