LC SM MM Simplex Duple Plastic Metal Optical Fiber Adapter

Newsun tech adopts high quality raw materials and produces the fiber adapter strictly according to international standard, which makes our adapters fully compatible with the products from other manufacturers in the market. The fiber optic adapters are divided into five major groups in Newsun tech, SC, LC, FC, ST and hybrid adapters.

Of the many components in optical networking system, fiber optic adapter may be the least conspicuous one, which tends to be ignored by IT mangers and directors. Though it is small, we can still not deny the fact that fiber optic adapter is of vital importance to the whole operating system for optical networks. 

A fiber optic adapter also called fiber optic coupler, is a medium component which is used to terminate the fiber optic cables or fiber optic connectors between two fiber optic lines. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad). Fiber optic adapters are employed in optical distribution frame (ODF), fiber optic communications equipment, measuring appliance and, so on. There are many types of fiber optic adapters, because of the diversity of the connectors, including female to female fiber adapters and female to male type fiber adapters. If a fiber optic adapter fits two different kinds of fiber connectors, it is called hybrid fiber optic adapters, such as LC to SC hybrid adapter.

LC adapters can be used for the connection of LC patch cables or LC connectors. There are different types including LC to LC, LC to FC, LC to SC, LC to ST, and LC to MU, etc. All these adapters can be available in simplex, duplex, quad, single-mode, multimode, UPC, APC, PC with plastic housing, zirconia sleeve, and optional bronze sleeve.

Adapters are designed for multimode or singlemode cables. The singlemode adapters offer more precise alignment of the tips of the connectors (ferrules). It is ok to use singlemode adapters to connect multimode cables, but you should not use multimode adapters to connect singlemode cables. This can cause misalignment of the small singlemode fibers and loss of signal strength (attenuation).

When connecting two multimode fibers, you should always make sure they are the same core diameter (50/125 or 62.5/125). A mismatch here will cause attenuation in one direction (where the larger fiber is transmitting light into the smaller fiber). Most adapters are female on both ends, to connect two cables. Some are male-female, which typically plug into a port on a piece of equipment. 

By linking two connectors precisely, fiber optic adapters allow the light sources to be transmitted at most and lower the loss as much as possible. At the same time, fiber optic adapters have the merits of low insertion loss, good interchangeability and reproducibility. Newsun Tech supplies a wide range of mating sleeves and hybrid adapters, including Fiber Loopback Module, Male to Female Fiber Optic Adapter, bare fiber adapter, FC Adapter, ST Adapter, SC Adapter, Quad LC Double deck Optical Adapter, Fiber Optic LC Adapter, and etc.
