ACT LC Fiber optic attenuator 1 dB

The ACT LC Fiber Optic Attenuator 1 dB is a compact in-line device designed to reduce optical signal power in single-mode fiber links. Fitted with LC connectors and finished in blue, this 1 dB fixed attenuator helps align signal levels between transmitting and receiving equipment to prevent receiver overload and maintain signal integrity in high-speed data transmission. Supplied as a single unit per pack, it is suitable for straightforward insertion into existing fiber connections without changing cable routing.

Advantages

This attenuator provides a precise 1 dB attenuation value to manage optical power with minimal return loss. The LC-to-LC connector format ensures compatibility with common networking equipment and patch panels that use LC ports. Its compact in-line design keeps insertion loss consistent while preserving the fiber connection geometry, and the blue housing aids quick visual identification during installation and maintenance.

Suitable for

• Adjusting signal levels in single-mode fiber networks
• Preventing receiver saturation in high-speed data links
• Use in patch panels, transceiver connections, and optical test setups
• Small projects or individual installations requiring a single attenuator

Key specifications

• Attenuation: 1 dB fixed
• Connector type: LC to LC
• Fiber type: single-mode (SM)
• Housing color: blue
• Package quantity: 1 piece
• Form factor: in-line, plug-and-play

How to use

To use the ACT LC 1 dB attenuator, first power down or follow hot-swapping procedures per your equipment guidelines. Insert the LC connector of the attenuator into the LC receptacle of the transmitting or receiving transceiver or patch panel, and connect the other end to the mating LC connector. Verify that connectors are clean before mating to avoid contamination-related losses. After installation, check link power levels and system performance to confirm the attenuation effect and ensure signal quality remains within acceptable ranges.

Recommendations

For reliable operation, clean fiber connectors with appropriate cleaning tools before inserting the attenuator. Use this 1 dB device where minor signal reduction is required; for larger power adjustments select attenuators with higher dB values. Avoid excessive bending or mechanical stress on the attenuator and attached fiber to preserve optical performance.
