Now it has widely applied in single mode fiber optic cable, analog CATV, GPON, GBIC. It was developed by Nippon Telegraph and Telephone. With the ever-increasing popularity in the market, the manufacturing cost for SC went down. SC, also called a square connector, stands for subscriber connector. In the next part, some details about the four connectors will be presented to you. In all, there are nearly 100 fiber optic connectors in the market, but only a few of them are applied frequently in the market - LC connector, SC connector, ST connector, FC connector etc. It needs to be aligned properly to the microscopic glass fibers completely in order to allocate for communication. What Are the Fiber Optic Connectors?Ī fiber optic connector terminates one end of a fiber optic cable and enables quicker connection and disconnection than splicing. In fact, those terms refer to the different types of fiber optic connectors. Customers may wonder what LC, ST, SC refer to. And we can see a lot of fiber patch cables available in the market, such as LC to LC fiber cable, single mode LC to ST fiber patch cable, single mode fiber ST to SC patch cord, single mode fiber cable with LC connector, etc. You can find its applications in CATV, active device interface, premise installations and telecommunication network.The introduction of fiber patch cables has realized the data communicating at a much higher rate. MTP/MPO connector is usually assembled with fiber optic cable. And MPO/MTP optical fibers are now being commonly used in the data center to provide quick and reliable operation during signal transmission. Because there are key-up and key-down, male and female MPO/MTP connectors in the market, MPO/MTP fiber connectors are more complicated than the other three common types mentioned above. It combines fibers from 8 to 24 fibers in a single rectangular ferrule. MTP and MPO are frequently used interchangeably. And it is actually a registered trademark of US Conec. MTP connectors have a lot of mechanical improvements over standard MPO connectors. ST fiber connector is widely applied in both long and short distance applications such as campuses and buildings, corporate network environments and military applications. The connector stays in place with a "twist-on/off" mechanism. It has an insertion loss of about 0.25dB. ![]() The housing and ferrule are made of metal. The ST connector has a bayonet-type housing and a spring-loaded ferrule. Now the SC connector has frequently been used in analog CATV, GPON, GBIC. It is an ideal connector for datacoms and telecoms applications including point to point and passive optical networking. It is a snap-in connector that uses a simple push-pull mating mechanism. The connector’s outer square profile together with its snap-coupling mechanism can allow greater connector packaging density in instruments and patch panels. The SC connector has a square body with a standard SC plastic housing and a metal ferrule. At the present market, there are single mode LC connectors and multimode LC connectors. It has been used in Cable TV, LAN, Data processing networks and FTTH/FTTP. The LC connector is becoming one of the most popular connectors in the market today. It is an ideal connector for SFP and SFP+ transceivers and XFP transceivers. It is characterized by 1.25mm zirconia ferrule, a small form factor (SFF) fiber optic connector housing and a snag latch giving an audible click upon engaging for reliable and high density connections. LC connector is also called Lucent Connector. In the following part, some details about different fiber connector types and their different uses will be illustrated. ![]() And LC, SC, ST, MTP/MPO, FC and MTRJ connectors are frequently used in the industry. In the present optical fiber market, there are nearly 100 fiber connector types. And the fiber connector can make connections more stable, as it can ensure the fiber ends are optically smooth and the end-to-end positions are properly aligned. Ferrule, sub-assembly body, cable, stress relief boot and connector housing are major components of fiber connectors. And the most widely used fiber connector types include LC, SC, ST, MTP/MPO, FC and MTRJ connectors. Are you really familiar with these common fiber connector types and how much do you know about them? This article will illustrate the differences between these six common fiber connector types and their different uses.įiber connectors are also called fiber optic cable connectors. As is known to all, fiber connectors are an integral component of optical fiber patch cable. Nowadays, we can see a lot of fiber connectors in the fiber connector market.
