What is the LC connector?

You're reading What is the LC connector?, posted on Thursday, March 10th, 2011 at 2:39 am in Science Of Technology, on BrainBloggers at the Technology blog. More after the jump.

The LC connector stands for lucent connector. It is mainly a connector and resembles a standard ceramic. The LC connector has been developed specifically for Telecommunication purposes. It is half the size of the convential connectors.

The acronym for LC Connector is Lucent connector. It is a small form-optic connector which is mainly made of fiber. It resembles the small standard ceramic and usually uses a 1.25mm ferule, which is half of the ST size. In other cases, it has to be a standard ceramic ferrule connector. It was developed by Lucent Technologies for use in TelCo environments and is greatly favored for single mode transmission. It has been standardized as the Fiber Optic Connector Intermateability Standards (FOCIS 10) in EIA/TIA-604-10.

The LC Connector have been incorporated with some common and proven technologies for the system to deliver as being easy to carry out the fiber optic interface. The most preferred telephone plug RJ-45 helps to provide support providing mechanism for, both the connecting system, and the time tested ceramic ferrule to terminate the fiber. These connectors include features such as single set design, having detachable clips for duplex and simple connectors and polarized. It complies with industrial standards, is half the dimension of normal connectors and having the push and pull mechanism which resemble RJ connectors.

There are two versions available. The first one is the LC Unibody jumper connector which is designed for 1.6-2.0 mm cordage and 3.0 mm cordage. The second version is the “behind-the-wall” or BTW which is designed to mount on 0.9 milimeter buffered fiber. LC connectors are offered with pre-radiused ferrules. They have numerous features and applications which are listed as below:


  • One piece design
  • Pull proof for jumper
  • RJ Style push and pull housing
  • Polarized
  • Anti-snag latch for BTW and jumper
  • PC finish
  • Standards compliant
  • Removable clips for simplex and duplex connectors
  • Pre-radiused connectors available
  • ½ the size of the standard connectors

There are various applications too for LC connector. For instance they are used in local area networks, data processing networks, tele-communication, premises distribution benefits, cable television and so on. A lucent connector is available in blue and beige color shades and it can be used in CATV, LAN, WAN and MAN applications. One even has the option to customize, where one can find some connectors have features and make it suitable for certain functions. It has the facility to accomodate various types of cable fibers. It has the ability to accomodate various types of cable fibres. The types of cable that can be accomodated are 2.4mm, 1.6mm, 900um and 2.9mm and so on. The main body is made of many parts such as capillary (Zirconia, a type of ceramic), tubing, flange (brass), spring (stainless steel), plug frame and stopper. The crimping is made of aluminum alloy plus Sumitube.

There are numerous benefits with Lucent connector. It has double density, maintains optical contact, it helps maintain receive/transmit direction, it helps guarantee high repeatability, helps to reduce cross-connect and improves durability. It is fielded mountable and the necessary tools are included in the 1032 B kit combined with latest version, D182959. The version comes with connector holders, polishing tool and microscope adapter.
