Fiber optic adapters form a small, but critical, part of the hardware used in an optical fiber cabling system. It is used for connecting fiber optic patch cords or pigtails together, often called as fiber optic adapter or fiber optic coupler.
Fiber optic adapters, also known as flanges or fiber optic connectors, are primarily used to connect two fiber optic connectors in a fiber cabling system, and are often assembled on various adapter panels and chassis.
When deploying a network, it is often necessary to connect two cables with the same connector or different connectors. Which product should you choose for fast cable connection and ensure stable performance? At this point, you need to use a fiber optic adapter with low insertion loss, durability, and repeatability. This article will mainly introduce the type of fiber adapter interface, structure, and the difference between fiber optic couplers and fiber adapter advantages and solutions.
Fiber Optic Adapter Definition
Fiber optic adapters, also known as flanges or fiber optic connectors, are primarily used to connect two fiber optic connectors in a fiber cabling system, and are often assembled on various adapter panels and chassis. Important fiber optic connection components are widely used in television networks, local area networks, video transmission, optical fiber communication systems, and FTTH fiber optic homes. Conventional fiber optic adapters are available in flanged and non-flanged versions, where the fiber optic adapter without a flange can be directly attached to a panel or tray, and the fiber optic adapter with a flange needs to be screwed.
Fiber Optic Adapter Interface Type
According to the diversity of fiber optic connectors, there are many types of interfaces for fiber optic adapters, as shown in the figure below. According to the same connector at both ends of the fiber adapter, its interface can be divided into six types: LC-LC, SC-SC, ST-ST, FC-FC, MPO-MPO, and E2000-E2000. According to the different connectors at both ends of the fiber adapter, its interface can be divided into six types: LC-SC, LC-ST, LC-FC, SC-FT, SC-FC, and FC-ST. These two ends have different connections. The adapter for the device is often referred to as a hybrid adapter. In addition, the use of fiber adapters for SC and FC interfaces is relatively more widely used in all interface types.
Fiber Optic Adapter Structure
As shown in the figure below, a common LC-LC duplex fiber adapter is used as an example. It is made of corrosion-resistant plastic, has good corrosion resistance and internal shading, and is made of stainless steel clips, full flanges, dust plugs. As well as high-precision ceramic bushings and other components, it can ensure that two connectors can be accurately connected while minimizing losses. It should be noted that the main function of the flange of the fiber optic adapter is to fix the adapter on the adapter panel. Therefore, a variety of fine and fixed flanges are particularly used for shooting.
Difference between fiber adapter and fiber coupler
As shown in the figure below, the design of the fiber adapter is very compact. It is a bridge between two cables that connect the same interface or two cables with different interfaces. The main reason for the fiber adapter and the fiber coupler is the connector type at both ends. Normally, if the two cables to be connected have the same type of connectors, they are called fiber couplers. If the two cables to be connected have different connectors, they are called fiber adapters. For example, a fiber optic adapter is used to connect the ST-ST connector. At this time, the connector at both ends of the fiber optic adapter is the same, so it can be called a fiber optic coupler. Otherwise, it is called a fiber adapter. However, fiber adapters have the same type of interface, but also have different types of interfaces. There are a total of twelve options.
Fiber Optic Adapter Benefits
Can provide a large number of high degree of matching and conversion adapters, including special male and female conversion optical adapter, with low insertion loss, good interchangeability, good repeatability, high temperature, acid and alkali resistant and stable performance. The following are more advantages of fiber optic adapters.
1.High protective dust plug
Each fiber adapter is equipped with a corresponding high protective dust cover, which can be kept clean, 100% to avoid contamination of the adapter and the cable by dust, and greatly reduce the failure rate.
2. Connect the cable + convenient and simple
It is possible to connect two identical connectors or different connectors. When two optical cables need to be connected, only two optical cables must be aligned with the ceramic sleeve and inserted separately.
3 high-precision ceramic casing
The fiber optic adapter uses a ceramic sleeve imported from abroad and adopts a high-density production process to achieve high-precision fast connection of the fiber end face, which is definitely your ideal choice.
4. Compact design and easy operation
Optical fiber adapters are lighter in weight, compact in design, easy to operate, and user-friendly to help you easily connect and remove cables.
Optical fiber adapter plays an increasingly important role in optical fiber connection. It is an inconspicuous and critical connection component. It has strong practicability and high cost performance. It is widely used, especially for television networks, local area networks, video transmission, and optical fiber. For applications such as communication systems and FTTH fiber-to-the-home applications, fiber optic adapters are a good choice and solution!

Optical fiber is the backbone of modern communications. Singlemode fiber dominates long distance applications because of its reliability; however,This fiber has an internal diameter of only 10 micrometers (us) and is very expensive.
It is well known that optical fibers can be classified into single-mode fibers and multi-mode fibers depending on the modulus of the transmission point. The core of a singlemode fiber is relatively thin, and the transmission frequency bandwidth, capacity, and transmission distance are long, but because it requires a laser source, higher cost. Multimode fiber such as Multimode attenuator、Multimode copper cable、OM1/OM2 Multimode PVC jack、Multimode indoor cable、Multimode MPO Cassette etc.
As fiber deployment has become mainstream, Multimode fiber has attracted much attention, currently Russian and Finnish researchers collaborate on a proof-of-concept program to further expand the use of multimode fibers with larger core diameters; researchers use high-power lasers and anisotropic materials and expect to develop optical transmissions Maintain coherence of the fiber. Maintaining the coherence of light is a necessary condition for realizing quantum computers and sensor networks. It also helps multimode fibers to replace expensive singlemode fibers in more remote communications applications.
Optical fiber is the backbone of modern communications. Singlemode fiber dominates long distance applications because of its reliability; however,This fiber has an internal diameter of only 10 micrometers (us) and is very expensive. The lower cost multimode fiber has an inner diameter of 100us, which is currently used for short-distance communication. Generally, it supports distances of 1,000 meters and 1-Gbit/s transmission speed.

Fibers that can maintain coherence are more advantageous than semiconductor sensors because they require little power. The result comes from the inability of distributed sensor systems to function. In addition, these fibers can be used not only in high-power laser systems, but also as sensors because changes in polarization characteristics result from changes in the environment that they sense accurately.
Protecting optical fibers has advantages over semiconductor sensors because they require little power and can handle,The result of a distributed sensor system. Not only can they be used in high power laser systems, but the use as sensors comes from the observed fact that changes in their polarization properties make it possible to accurately sense the changes caused by environmental factors.

Fiber lasers use optical resonators to reflect light back and forth, thereby causing lasers. At present, this laser is only finished
Using the basic mode (upper left in Figure 1), the power is limited to the 10 nm fiber capacity. Increasing the transmission power of large lasers leads to uncontrolled variations in the refractive index of the fiber, causing parasitic nonlinear effects. The solution adopted by Russian and Finnish researchers was to change the core and the inner protective layer (Figure 2). Russian and Finnish researchers have used this technique to confirm the concept that less than 1% of the energy transmitted through high-power lasers is lost in the 100us fiber. Researchers have completely preserved the polarization properties of optical fibers by creating an internal protective layer for the anisotropic properties of large optical fibers (indicating that they propagate only in the length direction because the internal protective layer is oval).
