Fiber Optical Attenuator Fixed Build - out or Fixed Male to Female
Fixed plug in optical attenuators (Fixed Build-out or Fixed Male to Female) use doped fiber to provide fixed level of optical attenuation. Typical attenuation
values are between 3 and 20 dB. It is used in optical systems where the optical power from a source is too high for the test equipment in use. Fixed plug
type fiber attenuator provides a connector plug (male) and an adapter socket (female) to connect between fiber patch cord and fiber adapter. Fixed
plug type optical 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.
◇Features:
Low Insertion Loss
High extinction ratio
High isolation
