What are the features of a fiber optic adapter?

The fiber optic cables are connected with an adapter from its internal open bushing to ensure a better connection between the optical fiber connectors. There are various types of fiber optic adapters available in the market. For example, the transformable optical adapters have fiber optic connectors of various interface types at both ends to provide a connection between the APC faceplates. For increasing the installation density and to save space, a duplex or multi-adapter is used, as it can quickly adapt as per the requirements.

 How many types of fiber optic adapters are available?

 Though many Fiber Optic Adapters are available in the market, such as FC, LC, SC, etc. At Telhua, you can find fiber optic adapters such as:

 SC Fiber Optic Adapter

 The shell of an SC hybrid Fiber optic adapter is rectangular in shape. In addition, the pin and the coupling sleeve used in its structure are similar in size and type to an FC adapter. One end of the pin is designed to use more APC or PC grinding methods, and the plug pin type is used for the casting method but without rotation. These fiber optic adapters are cost-efficient, easy to plug-unplug, have high compressive strength, and offer low insertion loss variations and high installation density.

 LC Fiber Optic Adapter

 The LC-type Fiber Optic Adapter is made with a convenient modular jack latch mechanism. The pins and sleeves used in its design are half the size of SC and FC adapter types. The small size increases the density of fiber connectors in the fiber distribution frames. If we speak by popularity, the LC Fiber adapters are one of the eBay choices in the single-mode SFF. Its application is growing at a stark rate for multi-mode uses.

 sc shutter adapter

SC adapter with shutter is equipped with a hands-free shutter mechanism that protects the behind-the-wall connector from dust contamination when the port is not in use.

MPO Adapter

MPO adapters improve your system’s design by providing a variety of flange styles that are challenges and mechanically compliant with industry standards.

How to choose a suitable fiber optic adapter?

 A wide range of fiber optic adapters are available in the market with very similar shapes and appearances; it almost becomes an obstacle for a buyer. Therefore, Telhua brings you a few points that will help you choose the suitable fiber optic adapter. Read the following tips:

 Fiber Cable Type

The selection criteria for fiber optic adapter primarily depends on the use. So, if you need a fiber adapter to connect to a similar fiber optic cable and connector, you can buy an adapter with a rectangular, square, or circular interface. On the contrary, if the fiber optic cable type to be connected is different, you need to buy a hybrid fiber optic adapter. The plus point of using a hybrid adapter is that it allows you to connect two different types of fiber optic patch cords. Therefore, understand your use and identify which kind of cable you want to connect before you make any purchase.

 Sleeve Material of the Adapter

 Another important thing is the material used for making alignment bushings. There are mainly two types of materials used one is ceramic, and the other is metal. The ceramic-made fiber adapters are known to work better than the metal ones as these do not deform.

 Hopefully, the above information will help you select the fiber optic adapter per your requirements and purpose.

 What is a fiber optic network adapter?

 Fiber optic network adapter (also known as fiber optic coupler), is one kind of fiber optic connectors, are the centering and connecting components of fiber optic active connectors. Optical fiber adapters are the most used optical passive components in optical fiber communication systems. Most optical fiber system are composed of three parts: two optical fiber connectors and anadapter. Two fiber optic connectors fit into the two fiber ends; the adapter acts as an alignment sleeve. In addition, couplers are mostly equipped with metal or non-metal flanges to facilitate the installation and fixation of connectors.

Both ends of the optical fiber adapter can be inserted into optical fiber connectors of different interface types to realize the conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO, E2000, etc. It is widely used in optical fiber distribution frame (ODF), optical fiber communication equipment, Instruments, etc., superior performance, stable and reliable. Some on the market also call fiber optic adapters fiber optic connectors, but these are actually two different products.

 What connector is used for fiber optic cable?

 Optical fiber connector refers to a detachable, movable, and repeatedly pluggable connection device that connects one optical fiber to another optical fiber, also known as optical fiber active joint. It can realize low-loss connections between optical fibers or between optical fibers and cables, effectively reducing the impact of optical fiber connections on signals. Optical fiber connectors are mainly composed of four parts: pins, connector bodies, optical cables and connecting devices.

Fiber optic connectors are divided into many different types. According to different transmission media, fiber optic connectors can be divided into single-mode fiber optic connectors and multi-mode fiber optic connectors; and according to different connector structures, they can be divided into LC fiber optic connectors, SC fiber optic connectors Fiber optic connectors, FC fiber optic connectors, ST fiber optic connectors, MPO/MTP fiber optic connectors, MT-RJ fiber optic connectors, MU fiber optic connectors, DIN fiber optic connectors, E2000 fiber optic connectors, and more.

 The LC fiber optic connector is developed by Bell Labs. The size of the pin and sleeve is 1.25mm, which is half of the SC/FC fiber optic transceiver. It adopts the jack (RJ) latch fastening method, and is generally used. on high-density fiber distribution frames.

 SC fiber optic connector is developed by Japanese NTT company, its shell is rectangular, the pin size is 2.5mm, and the plug-in pin and latch fastening method is adopted, and the insertion method is simple and convenient. The FC fiber optic connector is also developed by Japanese NTT company. The pin size is 2.5mm. However, the pin of the FC fiber optic connector is relatively short. The biggest feature of the device is that it is not easy to fall off after installation.

MPO/MTP fiber optic connector is a kind of fiber optic connector specially made for multi-fiber ribbon cable, with 4/6/8/12/24 cores and other fiber types. It is generally used in high-density fiber optic links.

In the use of the connector, it is very important to clean the end face of the connector, so as to ensure that the connector maintains a better working condition. There are two common cleaning methods for fiber optic connector end faces: contact and non-contact. As an indispensable device in the general wiring project, the fiber optic connector is small, but it has made a great contribution to the entire network.

 What are the four types of fiber optic connectors?

 1. ST-type optical fiber connector: ST-type optical fiber connector adopts a keyed bayonet locking structure (similar to BNC connection structure), the pin body is a precision ceramic pin with an outer diameter of 2.5mm, and the end face of the pin is The shape is usually PC face.

2. SC (F04) optical fiber connector: SC (F04) optical fiber connector is a molded plug-in coupling single-mode optical fiber connector, its structure size is the same as FC type, and the pin body is also the outer diameter of 2.5 mm precision ceramic pins, the end surface treatment adopts PC or APC type grinding method; the fastening method is plug type. This type of connector is cheap, easy to plug and unplug, small fluctuation of access loss, high compressive strength, and high installation density.

3. FC (F01) type optical fiber connector: FC type connector adopts metal thread connection structure, and the pin body adopts precision ceramic pin with an outer diameter of 2.5mm. According to the shape of its pin end face, it is divided into spherical contact Two structures of FC/PC and FC/APC with inclined spherical contact. The FC type connector is currently the most widely used variety in the world, and it is also the main variety used in China.
