What you must know about fiber optic adapter knowledge

- Sep 07, 2020-

The key to optical fiber connection is the precise alignment of the fiber core, so traditional connection methods (such as welding) have certain defects. The difference is that each fiber optic adapter has an alignment sleeve inside, which can ensure the accuracy of the connection and realize the high-performance connection between the fiber jumpers.

There are many types of fiber optic adapters. The following mainly introduces several common fiber optic adapters: LC fiber optic adapter, FC fiber optic adapter, SC fiber optic adapter and bare fiber optic adapter.

LC fiber optic adapter: This fiber optic adapter can be used for the connection of LC fiber jumpers or LC connectors. There are many types of LC-LC, LC-FC, LC-SC, LC-ST and LC-MU.

FC fiber optic adapter: This fiber optic adapter can be used to connect FC fiber optic jumpers or FC connectors. There are different types such as square, single-mode and multi-mode, but these different types of FC fiber optic adapters all have metal shells and ceramic sleeves.

SC fiber optic adapter: It can be used to connect SC fiber optic patch cords or SC connectors, and there are many types, such as standard female-female SC adapters and hybrid SC adapters. Most SC fiber optic adapters have ceramic ferrules, while the fiber type of SC fiber optic adapters with bronze ferrules is usually multimode.

Special bare fiber adapter: As a special fiber adapter, the bare fiber adapter can be used to connect bare fiber cables to optical devices. This type of adapter allows the cable to be installed in the connection slot, whether it is inserted into a matching or inserted Electronic equipment.

Since there are many types of fiber optic adapters, and the appearance of fiber optic adapters supplied by different suppliers are also very similar, you may not know how to choose. Generally speaking, when choosing an optical fiber adapter, you should consider the following two points.

1.Type of cable to be connected

If the fiber optic adapter needs to be connected to the same cable type and connector, you can use a fiber optic adapter with square, rectangular or circular interfaces. If the types of cables that need to be connected are different, you need to use a hybrid optical fiber adapter, which can connect any two types of optical fiber jumpers together. Since there are many types of hybrid fiber optic adapters, it is important to know what type of cable needs to be connected before buying.

2.The material of the fiber adapter to the sleeve


The alignment sleeve is the most important part of the fiber optic adapter. Some manufacturers will choose metal as the material for the alignment sleeve. However, it has been proven that the use of ceramic fiber adapters is much better than using metal as the alignment sleeve. This is because the ceramic crystal structure is very hard and will not deform over time like metal materials, so it can achieve rapid alignment and achieve high-precision fiber end-face connection.

Although the optical fiber adapter is relatively small and belongs to the small part in the optical fiber wiring system, this does not affect its important position in the optical fiber wiring system, and it needs to be cleaned like other optical fiber equipment. There are two main cleaning methods, namely Dry cleaning and wet cleaning.

1. Dry cleaning: First, insert a dry cleaning rod into the fiber optic adapter, turn it to clean and take it out, then align the cleaning rod to the inside of the sleeve, clean the connector inside the fiber optic adapter, and check whether there is any Pollution.

2. Wet cleaning: First, dip the cleaning rod in the fiber cleaning solution, insert the wet cleaning rod into the adapter, and rotate the cleaning rod on the surface of the sleeve, and then take a dry cotton swab to clean the connection inside the fiber adapter Check whether there is contamination on the end face of the connector.

For fiber optic adapters, fiber alignment is very important. If the fibers are not aligned correctly, a large loss will occur at the connection. If the loss is too large, the network will not operate. In an optical fiber communication system, no matter how simple or small the components, it will also play a vital role in the entire system.

In addition, OPTICO has many types of fiber optic adapters for you to choose from. These fiber optic adapters have the advantages of low insertion loss, good interchangeability, good repeatability, high temperature resistance, acid and alkali resistance, and stable performance. They are definitely your optical communication . An indispensable component in the network.
