Optický atenuátor ACT SC 7 dB

The ACT SC Fiber Optic Attenuator 7 dB reduces optical signal power in fiber optic networks to prevent receiver overload and maintain optimal system performance. It uses optimized ion-doped fiber technology for consistent fixed attenuation and is supplied with SC/UPC connectors for straightforward installation and broad compatibility. The unit is single-ended and intended as an inline fixed attenuator for systems requiring a 7 dB loss.

Advantages

The ACT attenuator provides stable, repeatable attenuation thanks to its optimized ion-doped fiber construction. SC/UPC connectors ensure low reflectance and easy plugging into standard SC ports. Available in a range from 1 dB to 15 dB, this model delivers a precisely fixed 7 dB loss suitable for managing high-power signals without adjustable settings.

Suitable for

• Preventing receiver overload in singlemode fiber links
• Laboratory setups and field installations requiring a fixed 7 dB loss
• FTTx, PON, and other telecom applications with SC/UPC interfaces

How to use

Insert the SC/UPC connector of the attenuator into the corresponding SC port on the transmitter or patch panel, then connect the other end of the fiber to the receiver or next link segment. The attenuator provides a fixed 7 dB reduction of optical power; no adjustment is necessary. Ensure connectors and ports are clean before mating to avoid additional losses or contamination.

Recommendations

Regularly inspect and clean SC/UPC endfaces with appropriate fiber cleaning tools before insertion. Verify system power levels after installation to confirm the 7 dB attenuation meets system requirements and to avoid under- or over-attenuation.
