Optical Fiber Attenuators

Optical fiber fixed attenuators are used in optical systems where the optical power from a source
is to high for the test equipment in use. The fixed optical fiber attenuator introduces an in-line fixed loss that will reduce the source power to an acceptable detection level. The attenuation level should be stable with temperature and wavelength for a stable reliable system.

Intelmac's range of in line fiber fixed attenuators is a reliable and cost effective solution that
connects direct to the source connector. Intelmac offers SC, FC, LC and MU fixed attenuators with an attenuation level between 1 and 20dB. The optical attenuators can be but coupled to increase the attenuation level.
