FC Attenuator Details
Yingda provide FC/UPC and FC/APC attenuators, the same size and structure, but only different ceramic ferrule, UPC is ultra plat endface, APC is 8 degree angel endface.
In order to distinguish both, will use different colors of dust caps on both sides, for example, green dust caps are for APC. Red or white for UPC.
This widely used female to male attneuator can be range from 1dB, 2dB, 3dB, 4dB,5dB till 30dB, with fixed optical attenuation in optical fiber built-in. The female interface to connect with FC connectors, and the male interface will be insert into the fiber optic test tools.
