![]() ![]() The global marketplace is majorly driven by the growing adoption of the fiber optic technology. ![]() and is expected to gain traction over the forecast period. The global fiber optic connector market is expected to reach USD 5.9 billion by 2025, according to a new report by Grand View Research, Inc. The business of global fiber optic connectors have achieved big success over the past few years. In this passage, we would mainly give brief introduction to the four most common fiber optic connector types. They have been widely used in the termination of fiber optic cables, such as fiber optic pigtail, fiber optic patch cables and so on. All fiber optic connectors have four basic components, which are the ferrule, connector body, cable, and coupling device. Each one has its own advantages, disadvantages, and capabilities. The common fiber optic connector types include ST, SC, FC, LC, MU, E2000, MTRJ, SMA, DIN as well as MTP & MPO etc. This article touches on the very basics of fiber optic connectors types, market as well as its installation. These connectors come in many configurations and usages. The main types of fiber optic connectors include: ST, FC, SC, and LC. A number of fiber optic connector types have been evolved and withstood the test of time to become industry standards. The industry standards of making connectors replaced the complex installation. Obviously there are many more influences that lead to the development, but I hope this helps you understand why all of the different connector types exist and how to choose the right one for your fiber cabling constructions.Over the years, fiber optic connectors are no longer a deep concern for network installers. The brief shows only a general idea about the development of commonly used connector types you have seen. Because of the high number of fiber strands available in a small connection, MTP ® assemblies are used for backbone, cross-connect, and breakout applications.īeyond these commonly used connector types, there are a multitude of specialty connectors appeared shortly in the history of fiber optic connector types. The MTP has 12 or 24 fibers in its MT ferrule. The MTP ® connector (an improved MPO connector, the MPO stands for Multi-fiber Push-On) was then developed to increase fiber density even more. Note: MTRJ connectors are always duplex in that they hold two fibers. The MTRJ connector closely resembles an RJ-style modular plug, even getting part of its name from the resemblance. This was the first connector to use the MT ferrule design as opposed to a 2.5 mm or 1.25 mm diameter ferrule. The MTRJ connector (or MT-RJ, stands for Mechanical Transfer-Registered Jack) was then developed to put transmit and receive fibers into one connector. LC connector was developed by Lucent Technologies (Alcatel-Lucent for now) and uses a retaining tab mechanism and the connector body resembles the squarish shape of SC connector, while MU connector looks like a miniature SC and is more popular in Japan. The LC connector and MU connector were developed to reduce the space required for connectors on patch panels as the patch panel densities increased. Note: E-2000 is a trademark of Diamond SA, Switzerland. It has a push-pull latch that retains the connector, a dust cap always in place, and a smaller size. The LSH(E-2000™) connector was developed as an improvement on the SC connector design. A big advantage of this push/pull connector over a FC connector is that less room is required between connectors on patch panels. The SC connector was then developed (in Japan by NTT, a Japanese telecommunications company) to eliminate having to screw and unscrew the connector every time and to reduce the cost by molding instead of machining the connector. ![]() FC was one of the most popular single mode connectors for many years but is been mostly replaced by SC and LC connectors which will be mentioned next. The FC connector and DIN connector improved on the ST connector by isolating cable tension from the ferrule, keying the location of the ferrule for angle polishing, and threading onto the adapter for a more positive connection. Although extremely popular for many years, the ST connector is slowly being supplanted by smaller, denser connections in many installations. The ST connector was one of the first connector types widely implemented in multimode fiber optic networking applications (rarely single mode). It was the first connector to use a 2.5mm ferrule. The ST connector is the oldest design of the connectors still in common use. Here lists the history of different fiber optic connector types, which could probably make some help. However, choosing an optical connector was proved to be extremely difficult in the ealier fiber cabling constructions. Nowadays fiber optic connector comes in several varieties, including SC, ST, LC, FC, MTRJ, E-2000, MU, MPO/MTP, etc. ![]()
