What is LC Fiber Connector?

Optical fiber connector refers to a detachable, movable, and repeatedly plugging connection device that connects one optical fiber to another optical fiber. Optical fiber connectors can be seen everywhere in life. In order to meet the needs of life, Optical fiber connectors often have many types. According to the different connector structure, it can be divided into LC fiber connector, SC fiber connector, FC fiber connector, ST fiber connector and so on. The following mainly introduces LC fiber connectors.

 

 

Definition of LC Fiber Connector

The LC fiber connector is a small form factor (SFF) connector, which is designed to join LC fibers where a connection or disconnection is required. The LC fiber connector was first developed by Lucent Technology for TelCo environment uses. Hence, LC stands for Lucent Connector mostly. In addition, LC can also stand for Little Connector and Local Connector. These LC fiber connectors utilize traditional components of the standard connector but with a 1.25mm ceramic ferrule.

 

 

Types of LC Fiber Connector 

LC fiber connectors have single mode and multimode tolerances. The polishing types of the LC fiber connector are available in UPC and APC. LC APC fiber connector has an eight-degree angle to minimize back reflection and can be recognized by its green colored housing and strain relief boot. While LC UPC fiber connector can be easily recognized by blue color. Generally, two versions of LC fiber connectors are available: jumper connector and BTW connector.

 

The jumper connector can be used to terminate simplex and duplex 1.6 to 2.0 mm cordage. It is convenient to engage and disengage because of a trigger and the standard latch. What’s more, jumper connector is intended for use in LAN, central offices, and in patch cords for premise distribution systems.

 

The BTW (behind-the-wall) connector is a shorter version of the LC intended for mounting on 0.9 mm fiber. It is typically utilized on the back side of equipment. Besides, BTW connector usually uses finger catch and extended latch, which makes the BTW connector engage and disengage easily.

 

 

Advantages of LC Fiber Connector

Nowadays, LC fiber connectors are very popular in the market. The following are several advantages of LC fiber connector.

(1) With LC fiber connector, the cost of the system can be reduced. LC fiber connector is half the size of the traditional SC fiber connector. Therefore it can doubles fiber density in shelves and outlets.

(2) The polarized feature of LC fiber connector helps maintain the transmitting or receiving direction and assures high repeatability.

(3) LC fiber connector has an anti-snag latch, which can improve durability and reduce the rearrangement work caused by the cross connection.

(4) It is time-saving for installation, because there is no need to install the field mountable connectors.

 

 

In a word, LC fiber connector provides the connection between two LC fiber cables, or a fiber optic cable and another optical component. In the use of LC fiber connector, it is very important to clean the end face of the optical fiber connector, so as to ensure the connector to maintain a better working state. As the indispensable device in the generic cabling project, although the LC fiber connector is small, it has made great contribution to the whole network.
