Fibre optic attenuators are used in fibre optic communications to reduce fibre power by a certain level. Fibre optic attenuators can be designed for use with various kinds of fibre optic connectors. The attenuators can be female to female which is called bulkhead fibre optic attenuator or male to which is called a plug fibre optic attenuator.

The most commonly used type is female to female type. Fibre optic attenuators name is based on the connector type and the attenuation level. Commonly used attenuation range is from 1dB to 20dB. Veekay fibre optic fixed attenuators have an established name for their stability& consistent losses, they also provide a reliable solution for fibre attenuations.

Typical available versions are in SC, FC & LC variants.
