  • LC Connectors

    The LC connector is a small form factor fiber optic connector. The LC connector resembles a small SC connector. Lucent Technologies first developed the LC connector for TelCo environment uses. Hence, LC stands for Lucent Connectors.

    The LC connector has been standardized as FOCIS 10 (Fiber Optic Connector Intermateability Standards) in EIA/TIA-604-10. The LC connector uses a 1.25 mm ferrule, half the dimension of the ST ferrule or a regular ceramic ferrule connector. The LC gives excellent performance and is greatly preferred for single mode transmission.

    Features of LC Connectors

    • Half the dimension of regular connectors
    • Push & pull mechanism like RJ connectors
    • Single set design
    • Polarized
    • Complies with industry standards
    • Detachable clips for simplex as well as duplex connectors

    LC Connectors decrease the room by roughly 50% all over the network. They make things easier for movements, additions, and modifications, thus preventing additional expenses. The LC Connector uses an enhanced edition of the well-known, user friendly RJ-style telephone connector that offers a reassuring clear click when connected. The latest single set design improves the connector’s strength and complies with side-load requirements of standard 2.5 mm connectors. Jumper LC connectors are equipped with detachable clips, making it easier to rectify polarity inaccuracies during termination or while duplexing simplex connectors in the field. The distinctive mixture of small sizes and the click of connectivity make the LC Connector a perfect pick for today’s high performance networks.

    LC connector applications include Telecommunications networks, Local area networks, Data processing networks, Cable television, Fiber-to-the-home, and Premises distribution.

      Fiber Optic Connectors


      First developed by Lucent Technologies for telecommunication applications, the LC series fiber optic connector is a small form factor pluggable type that finds use in transceivers. Similar to the SC type connector, the E-Systemizer LC fiber optic connector is easy to plug in or remove, providing a secure, precisely aligned fit conforming to FOCIS 3 EITA/TIA 604-03 standards. It is the most popular of fiber optic connectors in our range.


      header-arrow Compact, fool-proof design

      header-arrow Interface similar to RJ 45 with UL rated plastic housing and boot

      header-arrow Minimal back reflection and insertion losses

      header-arrow Precise alignment

      header-arrow Behind the wall style short connectors

      header-arrow Available in single piece or multi-piece types

      header-arrow Lowest insertion loss ST type connector with maximum mating cycles

      header-arrow Easy to install and use, total reliability


      E-Systemizer LC connectors have proven reliability in demanding environments and are best suited for:

      header-arrow Gigabit Ethernet, video and active device terminations

      header-arrow Multimedia, telecommunication networks and on-premises installations

      I have a strange problem with LC connector.
      I needed to connect switch to a router and in testing process they were sitting side by side.
      Connection was made with 10 feet LC to LC single mode duplex cable.
      There were no problems.
      As soon as I put devices to their production places (30 feet apart) and connected with the same type of cable (only 30 feet long) I had no connectivity at all. Suddenly I noticed that if I press retaining clip and pull out LC connector just a little bit connection was established.
      I plugged it back and connection was lost again. Problem was easy to reproduce. I have no idea what is a reason for that.
      Any help would be appreciated.
