Unlike the plastic-bodied standard connectors (SC) and Lucent connectors (LC), FC connectors use a circular screw-type fitting made of nickel-plated or stainless steel. The function of fiber optic connectors is to align and connect two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or any other fiber optic component. The connectors can be put on patchords, pigtails or components with single-mode (SM). A standard fiber optic connector is comprised of four primary elements: · Pin (Ferrule): A precision-engineered cylinder that holds the fiber in place. It acts as the primary alignment mechanism, typically crafted from ceramic or metal to ensure exact positioning. Typically, the housing is made of plastic. Quality connectors lose very little light due to reflection or misalignment of the fibers.
