ACT LC optický útlmový člen 5 dB

The ACT LC Fiber Optic Attenuator 5 dB reduces optical signal power to prevent receiver saturation and to match link power budgets in fibre optic networks. It features LC connectors in a compact in-line form factor and comes in blue housing. The single-unit pack supports precise 5 dB attenuation for singlemode fibre links where controlled signal reduction is required.

Advantages

This LC 5 dB attenuator provides predictable and stable attenuation with low return loss and minimal insertion loss beyond the specified 5 dB reduction. Its small, lightweight design allows simple in-line installation without modifying existing connectors, and the color-coded housing makes it easy to identify attenuation value in patch panels or splice locations. The product is suitable for field use and lab setups where a reliable fixed attenuator is needed.

Suitable for

• Adjusting power levels in singlemode optical links
• Preventing receiver overload in high-power transmitter scenarios
• Testing and commissioning of fibre optic networks
• Use in patch panels, media converters, and SFP/GBIC equipment

Key specifications

• Attenuation: 5 dB (fixed)
• Connector type: LC to LC (ferrule-style)
• Fiber type compatibility: singlemode
• Housing color: blue (color-coded for attenuation level)
• Form factor: in-line, plug-style attenuator

How to use

Insert the ACT LC 5 dB attenuator directly between two LC-terminated patch cords or between a patch cord and an LC port on networking equipment. Ensure connectors are clean before insertion to avoid contamination and additional signal loss. Align the LC connectors carefully and push until the connector latches engage; no tools are required for installation. When removing, depress the LC latch and pull straight back to avoid stressing the fibre.

Recommendations

Verify that a 5 dB fixed reduction meets the system power budget before installation. Use appropriate cleaning tools and inspect connector endfaces with a fibre microscope or inspection probe to maintain signal quality. Store the attenuator with protective caps when not in use and avoid excessive bending or mechanical stress on connected fibre.
