Manually Variable Optical Attenuator-1550nm

Manually Variable Optical Attenuator-1550nm

 

Fiber optical attenuator is common used passive device used in the fiber optic network to reduce the amplitude of a light signal at a certain level. There are kinds of attenuators, include adaptor type fixed attenuator, male to female plug-type attenuator, variable optical attenuator, In-line attenuator.  VFIBRE offer all kinds of optic attenuator with low wavelength sensitivity, high stability, high return loss and good reliability, our attenuator widely used for EDFA, DWDM and other high power output applications. All products are rigorously tested to meet the needs of optic network, compliance with RoHS standard.
