5/17/2023 0 Comments Fiber connector types![]() This connector is a duplex connector using two 2.5 mm ferrules and has a fixed shroud over the ferrules. The style is similar to that of an ST connector, but it uses a threaded connection, which makes it better suited for high vibration environments.įDDIconnectors are designed by ANSI for use in FDDI networks. They are primarily used with single mode fibers and used in telephone, instruments, and high-speed communication links. They have a high-performance thread mounting system and a keyed body for repeatability and intermateability. ESCON connectors are used to connect to the equipment from a wall outlet.Īn FC, or fixed connection, connector is constructed of an all-zirconia ceramic ferrule for durability. The shroud is over the ferrule and is spring-loaded and retracts. The main difference is its retractable shroud as opposed to a fixed shroud. It is similar to the FDDI connector-a duplex connector using 2.5 mm ferrules. ![]() D4 connectors were widely used in telco networks in the 80s to early 90s, but they are becoming an obsolete technology.ĮSCON’s name derives from its application in IBM's ESCON channel interface. ![]() It uses a smaller ferrule than SCs or FCs. Biconic connectors are becoming obsolete.ĭ4connectors are made from a composite zirconia ceramic ferrule for durability. It has a glass-filled plastic mold and started with the fiber being molded into the ferrule.

A more detailed description can be found in the next section. The video below gives a great brief description of the types of connectors. A coupling device is used instead of a male-female configuration. Extra strength is provided by a strain-relief boot added over the junction between the cable and connector body. The cable is attached to the connector body and acts as a point of entry for the fiber. The ferrule extends past the connector body to slip into the coupling device. It is usually made of metal or plastic and includes one or more assemblies that hold the fiber in place. ![]() The connector body, also called housing, holds the ferrule. Parts of the fiber optic connectors include the connector body, the cable, and the coupling device. The ferrule end is polished after insertion of the embedded fiber to provide the smooth interface required for coupling. The end of the fiber is held within the ferrule by either adhesive or crimping so that it becomes a permanent component. A component within all fiber optic connectors is called the "ferrule." The ferrule ensures alignment during connector mating and is often made from a hardened material such as ceramic, stainless steel, plastic, or tungsten carbide. End-to-end positions must align precisely. Reliable connection requires that fiber ends be optically smooth and square. An adapter is a mechanical device us ed to align and join two or more fibers with different connection types. Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or any other fiber optic equipment.
