Adapter Type Fixed Attenuator

This series of fixed attenuator has the same appearance as a regular fiber optic adapter. It achieves attenuation of optical signal by setting up an attenuation film inside a fiber optic adapter to ensure incomplete touch with fiber connectors. Due to this principle, the fixed attenuator is a great fiber optic attenuation solution for fiber optic patch cords in an optical link.

As a trusted and dedicated manufacturer of fiber attenuators, we can supply a wide selection of adapter type fixed attenuators including SC, LC, FC and ST versions. These fixed optical attenuators are only suitable for fiber optic connectors with PC type ferrule end face. The attenuation value can be 1, 3, 5, 7, 10, 15 and 20dB, and thus our fixed attenuators are applicable for optical signal with wavelength ranging from 1,250nm to 1,600nm.

Advantages of Adapter Type Fixed Attenuator
1. Great repeatability and interchangeability
2. Accurate attenuation
3. High reliability
4. Compliant with the IEC and RoHS standards

Applications of Adapter Type Fixed Attenuator
1. Testing instruments
2. Connection between devices
3. Connection between fiber optic patch cords
5. FTTx
