FC-Attenuator Series Fiber Optic Attenuators
FC-Attenuator Series Fiber Optic Attenuators
Price range: $17.60 through $33.00
Description
Product Description
- Attenuates optical signals
- FC-FC connectors, 2.2 mm wide keyway, compatible with single-mode and multi-mode fibers
- High repeatability, high return loss, low insertion loss
- Available with 2-port and 4-port integrated mounts
- Mounting holes for easy installation on posts, optical tables or breadboards
Fiber optic attenuators reduce optical power to prevent receiver distortion caused by excessive input power.

Technical Notes
- Fiber optic attenuators reduce optical power to avoid receiver saturation. The FC-Attenuator series provides precise core alignment, high repeatability, high return loss, and low insertion loss.
- Rubber caps are included on both ends for dust protection and storage.
- L-shaped mounting brackets with through holes allow secure mounting via M6 screws to optical posts, tables, or breadboards.
- Attenuation values are lasermarked on each unit. Available sets:
- 1 dB / 3 dB
- 5 dB / 7 dB
- 10 dB / 15 dB
