OptoNest Attenuation Fiber

OptoNest’s specialty optical fibers are fabricated for DWDM attenuator application with flat attenuation properties. The attenuation fibers have the potential to offer high reliability and stable input power endurance. OptoNest’s attenuation fibers are designed to be used for fixed or in-line type attenuator and terminator covering all optical communication wavelength (1250 - 1650nm) with 1 - 40dB/21mm.
