LC Fiber Connector Definition, Types And Advantages

What Is an LC Fiber Connector?

The LC connector is a small form factor (SFF) connector, which is designed to join LC fibers where a connection or disconnection is required. LC can stand for Little Connector and Local Connector. These LC connectors utilize traditional components of the standard connector but with a 1.25mm ceramic ferrule.

LC Fiber Connector Types

LC connectors have a single mode and multimode tolerance. The polishing types of the LC 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 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 the equipment. Besides, BTW connector usually uses finger catch and extended latch, which makes the BTW connector engage and disengage easily.

What Are the Advantages of LC Fiber Connector?

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

  •  With an LC connector, the cost of the system can be reduced. LC connector is half the size of the traditional SC connector. Therefore it can double fiber density in shelves and outlets.
  • The polarized feature of LC connector helps maintain the transmitting or receiving direction and assures high repeatability.
  • LC connector has an anti-snag latch, which can improve durability and reduce the rearrangement work caused by the cross connection.
  • It is time-saving for installation because there is no need to install the field mountable connectors.
