Product Description

Since our establishment, we are involved in providing the most durable products of fibre engineering to our customers. Our Fiber Optic Attenuator is widely used in telecommunication system, CATV, and testing equipment. The offered products are used to reduce the power in the optical signal. It reduces the power received by photo detector according to the limits of receiver. Our Fiber Optic Attenuator has high precision attenuation value and range.



  • Developed with durable plastic or metal material

  • Low reflection rate

  • Highly reliable




Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal.
It is often used to limit the optical power received by the photo detector to within the limits of the optical receiver.
