Variable optical attenuator - adapter type has a structure similar to an optical adapter. It utilizes the air gap between the two connectors to realize optical attenuation. However, the air gap can be continuously adjusted and fixed manually. This induces a variable optical attenuation from 0.5dB to 35dB and 40dB.
This component can be used in applications where optical attenuation needs to be frequently adjusted. It has very small size and is very low-cost.
- High attenuation precision
- Good stability
- Small size and light weight
- Easily adjusted
- Optical fiber communication systems
- Optical fiber CATV systems
- Optical power tests
Note: only FC type adapter VOA is available. This VOA suits FC/UPC or FC/APC connectors.
