Fibre Attenuator

An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. They are usually passive devices made from simple voltage divider networks. Fixed attenuators in circuits are used to lower voltage, dissipate power, and to improve impedance matching. In measuring signals, attenuator pads or adaptors are used to lower the amplitude of the signal a known amount to enable measurements, or to protect the measuring device from signal levels that might damage it. Attenuators are also used to 'match' impedances by lowering apparent SWR.

We offer 1 ~ 20dB and standard attenuation values at 3, 5, 10, 15 and 20 dB with FC, ST, SC or LC type connectors.
