This type of optical attenuators utilize the air gap between two connectors to achieve the optical attenuation. This fixed optical attenuator has a similar structure of a standard female-female optical adapter. It is simple, low-cost and compact.
- High precision in attenuation
- Small size
- Good stability
- FC, SC and ST types available
- Optical fiber CATV systems
- Optical fiber communication systems
- Test instruments
- Optical fiber sensors
a: Adapter type; a=FC for FC adapters, a=SC for SC adapters.
b: Attenuation in dB; b=3 for 3dB, b=5 for 5dB attenuation, etc.
