LC Fiber Optic Connector

LC fiber optic connector is similar to the SC connector, but will be smaller in size than the SC connector. It is made with an easy-to-operate modular RJ (registered jack ) latch mechanism, that is, a snap-on (small) square interface. LC fiber optic connectors are very common in single-mode network equipment and are generally used on optical transceivers. Judging from the current market occupancy, the position of LC fiber optic connectors is very stable and plays an important role in the environment of fiber optic connections.
So far, the advantages of LC fiber optic connectors are also obvious.

  • The first is its connector size, which is half of that of ordinary SC and FC interfaces. In this way, in the optical fiber distribution frame, the density of optical fiber connectors can be increased and space can be saved.
  • Secondly, its joint design has the characteristics of anti-locking, which enhances the stability of the pull-out resistance and improves the durability of the interface connection.
  • Finally, because it is a common fiber optic connector, it is more popular because of its diverse matching, simple and time-saving installation.
