ACT LC optički atenuator 3 dB

The ACT LC Fiber Optic Attenuator 3 dB reduces optical signal power in fiber networks to help match transmitter and receiver levels and avoid receiver saturation. Designed for use with LC-terminated multimode and singlemode links where a small, fixed attenuation is required, the attenuator is compact, easy to install and supplied in blue housing. Each pack contains one attenuator suitable for inline or adapter-mounted use in patch panels, transceivers and fiber distribution systems.

Advantages

The attenuator provides a stable, fixed 3 dB attenuation that helps prevent signal distortion from excessive optical power. Its LC connector interface ensures compatibility with widespread LC ports and patchcords while the compact form factor minimizes space requirements in dense installations. The product is color-coded to simplify identification and handling during installation and maintenance.

Suitable for (tasks / use cases)

• Adjusting optical power between transceivers and receivers
• Preventing receiver overload in short-reach fiber links
• Inline attenuation in patch panels and fiber adapters
• Field or lab testing where consistent 3 dB reduction is required

Key specifications

• Attenuation value: 3 dB (fixed)
• Connector type: LC
• Fiber compatibility: singlemode and multimode links (check system specifications before use)
• Housing color: blue
• Mounting: inline or adapter-mounted use

How to use

Install the LC attenuator by inserting it between LC patchcords or into the LC adapter of a panel or transceiver port, ensuring correct fiber alignment and secure connection. Confirm that the optical path is clean before installation; use appropriate cleaning tools to remove dust or contamination from connector endfaces. After installation, verify signal levels with an optical power meter or the receiving equipment to confirm the expected 3 dB reduction and proper system operation.

Recommendations

For reliable performance, avoid repeated insertion and removal which can wear connector endfaces. Keep spare dust caps on unused ends and store the component in a dry, static-free environment. When integrating into active links, validate receiver sensitivity and link budget to ensure the fixed attenuation aligns with system requirements.
