Fiber Optic
Attenuator is one kind of optical passive device which is used to debug the
performance of the optical power in the optical communication system,debugging
fiber optic instrument calibration correction, optical signal attenuation.And
used for the attenuation of the input optical power, avoid optical receiver
distortion due to input optical power powerful. The fixed fiber optic
attenuator can achieve the dual function of adapter and attenuators.
Adapter type fixed attenuator is the female to female fixed fiber optic attenuator,whichutilizes the air gap
between two connectors to achieve the optical attenuation. Fixed adapter
type attenuator is simple, low-cost and compact. It is recommended for use
where return loss is not a concern nor is absolute attenuation value.
