Fiber Optic Adapter/Attenuators

LC/SC/ST/FC/MU/E2000 Fiber Optic Male To Female Fixed Plug or Build-out Optical Attenuator

Product Description

Fixed fiber optic attenuators are available in LC, SC, ST, FC and MU style with APC and UPC polish. Generally, multimode systems do not need attenuators as the multimode sources, VCSELs, rarely have enough power output to saturate receivers. Instead, single-mode systems, especially short links, often have too much power and need attenuators. Therefore, fixed fiber optic attenuators are usually single-mode types. The most commonly used type is LC single mode female to male and female to female fixed fiber optic attenuator. Unlike the common female to male type mentioned above, the female to female fixed fiber optic attenuators have female type fiber optic adapter at the both ends, which are also therefore called fiber optic adapter type attenuators. They can be used as adapters and attenuators at the same time. For female to male fixed fiber optic attenuators, we can plug the patch cord to the female fiber optic adapter of the attenuator. And then plug the male plug connector of the attenuator to the equipment directly. For female to female fixed fiber optic attenuators, we should plug the two patch cords to the two female fiber optic adapter of the attenuator
