ST connector was introduced by AT&T and designed for multimode fibers. It was created by AT&T, featuring a 2.5mm ferrule. ST (Straight Tip) connector looks like an FC connector at the first glance. LC connectors also have polarized design for stable transmission. LC connectors can be divided into simplex and duplex structures. Because of their tiny size, LC is very suitable for high-density installation in FTTH and panels. It is a type of small form factor connector (SFF connector). LC means lucent connector or little connector, which features a 1.25mm ferrule. Many people also prefer standard connectors rather than ST connectors in telecommunications. SC is the most common choice for PON (passive optical network) and converters. It was introduced by Nippon Telegraph and Telephone and it has been widely used today thanks to its low cost and quick push-pull structure. SC (standard connector) features a 2.5mm ferrule. It is also called a square connector or subscriber connector. SC is the abbreviated name of the standard connector. These five types of optical fiber connectors can mainly represent the optic fiber market. But here we will only talk about the most common fiber connector types: SC, LC, ST connectors, FC, and MPO/MTO connectors. They come in different types according to polishing methods, booth length, and transmission media. There are more than one hundred kinds of optical fiber connectors on the market. What’s more, the boot is designed to protect optic fibers from external damage. The crimp eyelet increases the strength of connecting mechanism to protect the fiber inside. The connector sub-assembly is used to keep the fiber and cable in place and it is covered by connecting housing. The SC connector features a fiber ferrule, the diameter of which is 2.5mm. Take the SC connector as an example, it is composed of the dust cap, connector housing, connector sub-assembly, ferrule, crimp eyelet, and boots. In addition, the boot functions as a protector for optic fiber cable. The attachment mechanism makes the way to connect the connector body and optical equipment. The connector body helps support the ferrule and shield the optic fiber cables and this part is usually made of metal or plastic. It is usually made of plastic, metal, ceramic, and glass. The ferrule is the core part of the fiber connector, which allows for the alignment of optic fibers with accuracy. Structure of fiber connectorsĭifferent types of fiber connectors feature different structures, but they mainly have four main important parts: ferrule, connector, an attachment mechanism, and boots. And at that time optic fiber connectors may be difficult to use, but nowadays, it has been upgraded to be more convenient to use. There have been many types of fiber connectors on the market since the 1980s. It plays an important role in stable optic fiber transmission. A fiber connector is considered an important part of an optic-fiber cable. Optic fiber connectors usually feature a ferrule that helps keep the fiber in place and align strands of fibers to pass the light. It allows for quick connection or disconnection of optic fiber cables without splicing. What is an optic fiber connector?Īn optic fiber connector is used to connect two ends of optic-fiber cables. It is also used to provide home and office with fiber optic Internet connection, phone, and other services. Fiber optics can be applied in long-distance telecommunication. It is known that fiber optics cables can be classified into single mode and multimode. Optical fibers are bundled into a cable to carry light and this cable is called fiber-optic cable. What is fiber optics?įiber optics is the technology that transfers information with a pulse of light through glass or plastic fiber. But do you know knowledge about fiber optics, fiber-optic cables, and fiber connectors? This article will mainly walk you through detailed information about fiber connector types. It can keep high speed in long-distance data transmission. Nowadays, Fibre optic broadband has been a new way to connect Internet.
