A fiber optic connector, also known as a fiber optic patch cord or patch fiber, is a key component in a fiber optic communication system used to make a detachable connection between optical fibers. It enables maximum coupling of optical energy from one fiber to another while minimizing the impact on the system by precisely mating the two end faces of the fibers.
A fiber optic connector typically consists of three main components: a ferrule, an alignment sleeve, and a housing. The ferrule holds the end of the fiber and ensures alignment; the alignment sleeve maintains precise alignment between the two connector ferrules; and the housing protects the ferrule and alignment sleeve and provides mechanical support.
Fiber optic connectors play a crucial role in fiber optic communication systems, and their performance directly affects the transmission quality of optical signals and system reliability. With the continuous development of fiber optic communication technology, the performance of fiber optic connectors is also improving to meet the demand for higher bandwidth, lower loss and more reliable connections.
