How Many Types of Connectors Do Fiber Optics Cables Use?

When you install a fiber optic cable, the connector style you use is dependent on your equipment and the type of fiber. Many network applications require LC connectors, which are almost universally used for high-density installations. Each connector style is designed for a specific fiber type, which varies in cladding and core diameter. For example, a 9/125 connector is used with single mode fiber, because it has a 9-um core diameter and a 125-um cladding diameter.

MPO connectors are often called male/female connectors. The connector bodies have pins and holes to allow the fibers to fit together properly. These pins and holes are used to guide mating. The connectors are held together by a mating adapter, which aligns the keys. When plugged into a cable, the MPO connector keys are either pointing up or down relative to the numbering of the fibers.

MPO connectors can be broken down into duplex and multiplex connectors. Type B Mating Adapters, for example, swap the color code of the fibers. Depending on the network component, you can choose which of the MPO components you need. While the exact connection methods vary across manufacturers, there are several official options listed in TIA 568. This article will outline the different types and their uses.


When connecting two devices over long distances, fiber optic cables use one or more connector types. Depending on the application, the connector may be single-mode or multimode. Single-mode fiber cables have a smaller diameter core than multimode fiber cables and are used primarily for telephony. Multimode cables, on the other hand, use a larger central core that measures 50 microns. Single-mode cables require a specific connector type.

In order to connect two pieces of fiber, the connectors must align and couple correctly. This is accomplished by providing a mechanical connection point and aligning the fibers. In addition, connectors may also incorporate adapters, which are mechanical devices that align the fibers and ensure proper alignment. Here’s an explanation of the various connector types. Let’s look at some common types of connectors. It may be confusing to choose the right connector for your particular application, but don’t fret!


There are several types of connectors for fiber optic cables. Each type uses a unique mechanical design to connect two fibers together. The connectors are primarily comprised of a connector body, an adapter, and a ferrule. The connector body contains the ferrule, which extends from the fiber and slips into the coupling device. The cable is then connected to the connector body and a strain-relief boot is added to the junction of the two fibers.

ST connectors were common in the late 80s and early 1990s. These connectors were spring-loaded, cylindrical, and have a bayonet design. These connectors were used in long-line and campus multimode networks. These connectors have a low cost and are easy to install. Their keyed “slot” design helps keep them firmly mated to the fibers. The ST connector’s limited length and lack of support for angled polish has made it a less common connector.

The type of connector you use depends on the equipment and fiber being used. LC connectors are commonly used in high-density installations and are almost exclusively used in network applications. There are several different types of connectors, each designed to work with a certain type of fiber. For example, a single-mode fiber connector uses a 9/125 connector, where 125 um is the diameter of the cladding.

APC connectors are used for applications where return loss is an issue. These cables are best suited for high-precision signals, such as those used in video delivery via RF signals. They are also ideal for use in 5G Base Stations and broadcast systems. This type of connector is also used in some industrial settings and for small sells. While all of the various types of connectors are widely used, a few are particularly useful for certain applications.
