The FC Mechanical Attenuator from Fibramérica is designed to provide precise optical signal attenuation for high-performance fiber optic systems. Available in values from 1dB to 25dB in 1dB increments, it supports accurate signal level control for various single-mode applications.
Constructed to meet IEC61754 standards and RoHS compliance, this attenuator ensures excellent performance and environmental safety. It supports both UPC and APC polishing types and is compatible with standard wavelengths of 1310nm and 1550nm, making it highly versatile in telecom, FTTH, and data transmission networks.
Its robust build allows for field durability and repeated use without performance degradation. Designed to fit seamlessly with FC connectors, this attenuator offers excellent return loss values—≥50 dB (UPC) and ≥60 dB (APC)—ensuring minimal back reflection and optimal network stability.
Ideal for labs, ISPs, system integrators, and field technicians, the FC Attenuator is a trusted tool for testing, calibration, and real-time signal adjustment in optical communication environments.
