Product Description

This SC/APC Fixed Fiber Optic Attenuator (Male-Female Type) is designed to reduce optical signal power by a fixed level without distorting the signal waveform. Ideal for singlemode fiber applications, it features a simple plug-in form factor compatible with SC/APC connector interfaces. The attenuator is constructed with high-quality ceramic ferrules and precision doped fiber or air gap structure to ensure reliable attenuation performance and signal stability over a wide range of frequencies.

Quality Assurance

Each attenuator is tested for IL/RL and attenuation accuracy before shipping. RoHS and CE compliant. Produced under ISO 9001 certified system.
