Silicon Valley, CA, USA
Overview
This FC/APC male-to-female fiber optic attenuator is designed to reduce the optical power level in singlemode fiber optic links. By introducing a precise 11dB reduction, this device prevents receiver saturation and improves signal integrity in systems operating at 1310nm and 1550nm wavelengths.
Engineered for consistent performance, this build-out style attenuator features a robust housing that provides a reliable connection between existing patch cords and active network hardware. It is well-suited for use in telecommunications, data centers, and fiber optic test laboratories where signal management is critical for maintaining network performance.
Key Features
-
Singlemode Compatibility
Optimized for 1310/1550nm operating wavelengths to ensure low loss and compatibility with standard singlemode networks. -
Fixed 11dB Attenuation
Provides a precise, stable signal reduction to protect sensitive optical receivers from over-driving. -
FC/APC Connectivity
Utilizes angled physical contact (APC) polishing to minimize back-reflection and enhance return loss performance. -
Male-to-Female Configuration
Standard build-out design allows for quick integration between a patch cable and equipment port. -
Compact Design
Small form factor ensures it does not interfere with high-density rack configurations. -
Rugged Construction
Durable housing protects the internal optical elements from environmental stress during operation.
Applications
- Telecommunications networks
- Data center fiber management
- Optical signal testing and lab calibration
- Preventing receiver saturation in high-power fiber links

Frequently Asked Questions
What is the primary function of this attenuator?
It is used to reduce the signal strength in a fiber optic circuit to prevent receiver saturation.
Can this be used with multimode fiber?
No, this is specifically designed for singlemode fiber applications.
Does this require an external power supply?
No, this is a passive optical component.
What does the APC designation mean?
APC stands for Angled Physical Contact, which helps reduce back-reflections (return loss) in the fiber link.
How do I install this device?
The male end connects directly to a female adapter port (or bulkhead), and your existing patch cable connects to the female end of the attenuator.
