FC/APC Simplex Single-mode Fiber Attenuator, up to 20dB

These FC/APC (Angled Polish) single-mode fiber attenuators are commonly used in fiber optic communications to reduce the power level over a fiber cable by controlling the signal loss passed through the fiber. This attenuator is designed to be permanently installed. Metal ion doped fiber High-power light source durability Wavelength independence Attenuation levels ranging from 1dB to 20dB 1310nm, 1550nm, and 1310/1550nm dual wavelengths
