1. Attenuators

    A fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. Tech Optics attenuators can be supplied featuring a range of technologies to suit the application including air-gap and metal-ion doped fiber to reduce the light signal as it passes through. Please consult us for the best solution for your requirements.


    • Flat spectral attenuation
    • Low polarisation dependent loss (<0.1dB)
    • Typical optical return loss of <-55dB
    • High power-handling capability
    • Standard attenuation levels ranging from 5dB to 20dB, plus custom configurations.
    • Available in ST, SC, FC and LC styles as standard
