Fiber optic connector can be installed by various methods depending on the connector types. While connecting, one has to make sure that the ends have a smooth finish and is free from defects such as hackles and fractures. It is essential to remove the coating of the fiber and connect the connector by applying epoxy or by crimping. Subsequently, the fiber end has to be given a good optical finish by cleaving and polishing. Any impurities such as dirt change the geometrical propagation patterns of light and cause scattering. Fiber optics connectors are considered safe, as they are not affected by electromagnetic fields. They are low weight and have high electrical resistance. These connectors are cost effective and are usable even by untrained personnel. Fiber optics connectors have low data losses over long distances and have a high transmission capacity. It is no wonder that the era of telecommunications and networking has extensively adopted fiber optic connectors. The primary market for fiber optic connectors is the optical network application. Optical networks transmit voice and data across the country and around the world. The rapid expansion in the use of the Internet drives the optical market, including fiber-optic connectors. How to assemble a fiber optic connector? The most critical part, where the fiber is mounted, is the ferrule. Ferrule is a long, thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber's cladding diameter which is usually 125um.Fiber connector ferrules are made from several types of materials including ceramic(Zirconia), stainless steel and plastic. The ferrule's job is to center and align the fiber and protects it from mechanical damage.The end of fiber is at the end of the ferrule, where the fiber end is polished smooth either flat or with a curvature.The ferrule is mounted in the connector body and then the connector body is attached to the fiber optic cable structure. Finally, a strain-relief rubber boot protects the connector-cable junction.
