Fc Fiber Optic Attenuator

The FC fiber optic attenuator is a high-precision passive component designed to reduce optical signal power steadily without distorting integrity. It features a threaded FC connector for secure, vibration-resistant mating and operates across the 1260–1650nm wavelength range, compatible with single-mode (9/125μm) systems. Offering 1–30dB attenuation with tight tolerance, it delivers high return loss (UPC ≥50dB, APC ≥60dB) and low PDL. Widely used in telecom backbones, lab testing, military and industrial systems, it prevents receiver overload, balances signal levels, and ensures reliable performance in harsh or high-stability demand scenarios.
