Fiberoptic connector types chart

Take the SC connector as an example, it is composed of the dust cap, connector housing, connector sub-assembly, ferrule, crimp eyelet, and boots. The SC connector features a fiber ferrule, the diameter of which is 2.5mm. The connector sub-assembly is used to keep the fiber and cable in place and it is covered by connecting housing. The crimp eyelet increases the strength of connecting mechanism to protect the fiber inside. What’s more, the boot is designed to protect optic fibers from external damage.

In general, the single-mode cable comes with a yellow or blue jacket and a multimode cable feature an orange or green cover.

Different types of fiber connectors feature different structures, but they mainly have four main important parts: ferrule, connector, an attachment mechanism, and boots.

SC is the abbreviated name of the standard connector. It is also called a square connector or subscriber connector. SC (standard connector) features a 2.5mm ferrule. It was introduced by Nippon Telegraph and Telephone and it has been widely used today thanks to its low cost and quick push-pull structure. SC is the most common choice for PON (passive optical network) and converters. Many people also prefer standard connectors rather than ST connectors in telecommunications.

There are two basic types of fiber optic cables: single mode and multimode. Is your fiber optic cable single mode or multimode? Single mode fiber optic cable allows for one light mode to propaganda at one time, while multimode means that multiple light modes can pass through the fiber. The multimode also features a larger central core than the single mode to allow for different rays of light. You can identify whether the cable is single mode or multimode by the jacket color.

Nowadays, Fibre optic broadband has been a new way to connect Internet. It can keep high speed in long-distance data transmission. But do you know knowledge about fiber optics, fiber-optic cables, and fiber connectors? This article will mainly walk you through detailed information about fiber connector types.

Fiber optics is the technology that transfers information with a pulse of light through glass or plastic fiber. Optical fibers are bundled into a cable to carry light and this cable is called fiber-optic cable. It is known that fiber optics cables can be classified into single mode and multimode. Fiber optics can be applied in long-distance telecommunication. It is also used to provide home and office with fiber optic Internet connection, phone, and other services.

There are many types of connector terminations. Should you choose epoxy and polish termination or quick termination connectors? It depends on the installation quality and cost. Let’s take a look at some of your options.

LC means lucent connector or little connector, which features a 1.25mm ferrule. It is a type of small form factor connector (SFF connector). It was developed by Lucent Technologies. It also features a push-and-pull design. Because of their tiny size, LC is very suitable for high-density installation in FTTH and panels. LC connectors can be divided into simplex and duplex structures. LC connectors also have polarized design for stable transmission.

ST (Straight Tip) connector looks like an FC connector at the first glance. It was created by AT&T, featuring a 2.5mm ferrule. ST connector was introduced by AT&T and designed for multimode fibers. It is easy to operate thanks to its spring-loaded design. ST connectors are widely used in both long and short distance applications such as office and campus fiber applications and network applications.

An optic fiber connector is used to connect two ends of optic-fiber cables. It allows for quick connection or disconnection of optic fiber cables without splicing. Optic fiber connectors usually feature a ferrule that helps keep the fiber in place and align strands of fibers to pass the light. A fiber connector is considered an important part of an optic-fiber cable. It plays an important role in stable optic fiber transmission.

All in all, you need to know what equipment the fiber connector will be plugged into and what fiber optic cables you will use and then choose the best fiber connector. If you are still confused about choosing the right type of connector, you can take a look at the following chart.

If you want to choose one connector for a high-precision optical fiber application, APC is your first choice. But if you don’t need a so precision optical fiber signaling, UPC is great for most optical fiber applications.

There are more than one hundred kinds of optical fiber connectors on the market. They come in different types according to polishing methods, booth length, and transmission media. But here we will only talk about the most common fiber connector types: SC, LC, ST connectors, FC, and MPO/MTO connectors. These five types of optical fiber connectors can mainly represent the optic fiber market.

You may also hear MPO or MTP connectors, which have been very popular in recent years. It is a connector that can combine 12 to 24 fibers in a single ferrule. In addition, it supports 40G and 100G parallel fiber connectivity. MPO/MTP connectors are used in high-density network cabling systems, e.g. data centers.

Fiber connectors also come in single mode and multimode. And single mode fiber connectors usually have blue or green covers, while multimode connectors feature beige covers. But different manufacturers may have different color choices, so you’d better verify it from the suppliers before buying. With the development of technology, many fiber connectors such as FC and LC are compatible with both single mode and multimode fibers.

The ferrule is the core part of the fiber connector, which allows for the alignment of optic fibers with accuracy. It is usually made of plastic, metal, ceramic, and glass. The connector body helps support the ferrule and shield the optic fiber cables and this part is usually made of metal or plastic. The attachment mechanism makes the way to connect the connector body and optical equipment. In addition, the boot functions as a protector for optic fiber cable.

There have been many types of fiber connectors on the market since the 1980s. And at that time optic fiber connectors may be difficult to use, but nowadays, it has been upgraded to be more convenient to use.

FC connector is the first ceramic-shaped connector. It usually features a screw-look housing made of stainless steel or nickel plating. The alignment key and screw-design motion make the FC connector great for single mode fibers and in an environment full of vibration. It has been widely used in fiber optic networks in the past but has gradually been replaced by other connectors in recent years.
