Specifications

Description

A Mechanical Adjustable Fiber Attenuator is a passive optical component that uses a mechanical mechanism—typically a rotating dial, screw, or sliding element—to manually vary the attenuation (signal loss) in an optical fiber link. It physically adjusts how much light is allowed to pass through the fiber by misaligning fibers, bending fibers, or inserting variable optical filters, thereby reducing the optical signal power in a controlled way.
It is widely used in fiber optic systems to test, balance, or protect optical signals by introducing a variable, controlled loss.

Features

Manual Attenuation Control: Easily adjustable by turning a knob, dial, or screw.
Stable and Reliable: Mechanical design ensures consistent attenuation once set.
Broad Wavelength Compatibility: Works over typical telecom wavelength bands (e.g., 1260-1650 nm).
Low Insertion Loss at Minimum Attenuation: Minimal impact on signal strength when fully open.
Compact, Rugged Design: Suitable for lab and field environments.
Connector Options: Compatible with FC, SC, LC, ST, and APC/UPC connectors.
High Return Loss: Minimizes back reflection in fiber links.
Attenuation Range: Typically adjustable from 0 dB up to 30 dB or more.
No Power Required: Completely passive and easy to integrate.

Specifications

Attenuation Range: 0 – 30 dB
Operating Wavelength: 1260 – 1650 nm
Insertion Loss: = 0.5 dB (at 0 dB attenuation)
Return Loss: = 50 dB (UPC), = 60 dB (APC)
Connector Types: FC/SC/LC/ST (APC or UPC polish)
Fiber Type: Single Mode Fiber (9/125 µm)
Operating Temperature: -20°C to +70°C
Attenuation Adjustment: Mechanical screw or dial

Ideal Uses

Manual signal power control in fiber optic testing and maintenance.
Field and lab environments where precise, repeatable attenuation is needed.
Protecting optical receivers from signal overload.
Simulating fiber loss or cable faults during system troubleshooting.
Fine-tuning power levels in optical communication systems.
Educational and training setups for understanding fiber optic signal attenuation.
Temporary or semi-permanent installation where simple attenuation adjustment is required.

Why Choose Mechanical Adjustable Fiber Attenuator?

Simplicity & Reliability: No power or software needed; simple mechanical operation.
Cost-Effective: Affordable solution for manual attenuation adjustment.
Precise Control: Fine mechanical tuning allows exact signal level setting.
Durable: Rugged enough for both lab and field use.
Easy Integration: Fits seamlessly into existing fiber optic systems.
