Zirconia ceramic ferrule is the most precise component in fiber optic connectors (such as common FC,SC,LC,and MPO connectors),It is a microscopic sleeve with two core functions:
Precision fixing: It securely holds one or more extremely thin glass optical fibers (typically with an outer diameter of 125μm) within its center bore,Precision docking: When two fiber optic connectors are docked using an adapter,the end faces of the two ferrules are precisely aligned,ensuring that the light signal from one fiber is transmitted to the other fiber as much as possible,minimizing connection loss and signal reflections,
