Attenuators
An optical attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fibre. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. Fibre optic attenuators can be designed to use with various kinds of fibre optic connectors. The attenuators can be female to female known as bulkhead fibre optic attenuator or male to female known as a plug fibre optic attenuator. Bulkhead and plug types are designed without cables; another type inline fibre optic attenuator is designed with a short length of fibre optic cable.
