The different polishes on the ferrules were created to increase the efficiency of light transmission at the connecting points and minimize the amount of back reflection. Within the different connector styles, technicians need to be aware of the polish styles of the ferrules. However, generally, the most common types technicians encounter are LC connectors, SC connectors, ST connectors, and MPO connectors. What are The Types of Fiber Optic Connectors?Īs mentioned, there have been hundreds of fiber connectors introduced to the market over the years. It is often a latching clip or a bayonet-style nut. The coupling mechanism is the part of the connector body that holds the connector in place once attached to a device or cable. This is a plastic structure that holds the ferrule and attaches to the cable’s jacket and enables a technician to “mate” fiber optic cables. The connector housing or connector body is the largest component of a fiber optic connector. Ferrules typically hold one strand of fiber and are made of ceramic, plastic, or metal. The center is hollow and creates a firm grip on the fiber. ![]() The ferrule is the piece that holds the glass fiber. While hundreds of connectors have been introduced over the decades, only a small group of them are commonly used by fiber technicians.įiber optic cable connectors have several components, but the main three components are: the fiber ferrule, the connector housing, and the coupling mechanism. Basically, high-quality connectors will not lose much light because of reflections from a poor connection or misaligned fibers. The majority of fiber optic connectors are designed with ferrules that house and align the fibers for connection, allowing light to pass from one cable to the next, an active device, a tester, etc.įiber optic connectors are critically important for the reliability and performance of the network they are connected to. Unlike splicing, where two cable cores are permanently connected by fusion – heating the ends of two glass fiber cores to about 1,600 ֯ C and then joining them – the use of connectors gives a fiber technician the ability to easily test, maintain, and reconfigure networks. This article will provide an introduction and brief overview of the most commonly used fiber optic connectors from descriptions, to common uses, to a few points to keep in mind when working with fiber optic cabling.įiber optic connectors are special pieces specifically designed to mechanically align and join, or terminate optical fibers, making it possible for two cables to be connected and disconnected quickly and safely. It’s this steady expansion of fiber cabling that is spurring the need for advancements in the fiber optic connector market. The use of fiber optic cabling has been steadily growing since the late 70s and early 80s. Today fiber optic cabling is being used to replace copper cables in many regions.
