ACT LC fiber-dæmper 10 dB

The ACT LC Fiber Optic Attenuator 10 dB reduces optical signal power in fiber networks to help match transmitter output to receiver sensitivity. With LC-style connectors and a compact inline design in blue housing, this 10 dB fixed attenuator provides a predictable reduction of signal level for single-mode fiber systems. Supplied as a single piece per pack, the device is suitable for use in patch panels, equipment racks, and inline fiber runs where controlled attenuation is required to prevent receiver overload and preserve signal integrity.

Advantages

The ACT LC 10 dB attenuator delivers stable and repeatable attenuation with minimal insertion loss beyond the specified 10 dB reduction. Its LC connectors ensure compatibility with standard LC-terminated fibers and patch cords while the compact form factor simplifies installation in confined spaces. The blue color coding helps identify attenuation value quickly during maintenance and upgrades. Constructed for consistent optical performance, the attenuator supports high-speed data transmission without introducing significant back-reflection or distortion when used within its specifications.

Suitable for (tasks / use cases)

• Adjusting optical power to match receiver sensitivity in single-mode networks
• Preventing receiver saturation in high-power transmitter links
• Testing and troubleshooting link margin and signal level in LAN and metro networks
• Integration into patch panels, fiber distribution frames, and inline connections

Key specifications

• Attenuation: fixed 10 dB
• Connector type: LC (female/male compatibility with LC patch cords)
• Fiber type: single-mode
• Housing color: blue
• Package quantity: 1 piece per pack
• Form factor: inline / plug-in style attenuator

How to use

Install the attenuator by inserting it between two LC-terminated fiber connectors, ensuring clean connector endfaces before connection to avoid signal degradation. Align and push the LC connector until it clicks or seats securely; no tools are required for standard insertion. Verify the optical power at the receiver end after installation to confirm the expected 10 dB reduction and adjust link components as needed. For temporary testing, the attenuator can be inserted and removed as part of diagnostic procedures.

Recommendations

Clean fiber connectors with appropriate lint-free wipes and fiber cleaning solution before each use. Avoid bending the fiber beyond recommended radii near the attenuator and store the device in a dust-free environment when not in use. Use the attenuator only within specified fiber types and power levels to ensure reliable performance.
