VariableFiber Optic Attenuator — Adjustable Optical Power Control
Variable (adjustable) fiber optic attenuator with continuous attenuation control for precise optical power management. Plug-type female-male design with SC/APC interface. Supports single mode and multimode fiber systems for network testing, FTTH optimization, and laboratory applications.
Technical Specifications
Engineered For Performance
Continuously Adjustable Attenuation
Smooth mechanical adjustment provides stepless attenuation control from 0dB to 30dB, enabling precise optical power tuning without swapping fixed-value attenuators.
Compact Plug-Type Form Factor
Female-male plug-in design connects directly into SC/APC ports on equipment and patch panels, eliminating the need for additional patch cords or adapters.
High Return Loss
APC angled polish maintains ≥60dB return loss across the full attenuation range, preventing back-reflection issues in sensitive FTTH and analog optical systems.
Dual Mode Support
Compatible with both single mode (9/125μm) and multimode (50/125μm) fiber, providing a single tool for diverse testing and optimization scenarios.
Typical Applications
Network Testing & Troubleshooting
Simulate varying link losses for BER testing, receiver sensitivity evaluation, and fault isolation in live and laboratory fiber networks.
FTTH Signal Optimization
Fine-tune optical power levels at ONU receivers during GPON/XGS-PON commissioning to achieve optimal signal strength for each subscriber location.
Optical Power Management
Real-time attenuation adjustment in DWDM, EDFA, and amplified network segments where optical power levels vary with channel loading and amplifier gain changes.
