Optical Fibre Connector Types

    LC Fibre Optic Connectors

    LC Connectors

    Lucent Connectors (LC) are small in size, with a ferrule measurement of 1.25 (exactly half the ferrule size of an SC connector), and is what would be classified as a Small Factor Connector.


    Their size is useful for high-density patch panels when installation space is limited. These are primary used for single-mode installations, but can also be used in multimode installations.



    LC connectors use a push & pull latching mechanisms, enabling faster and easier installation. LC connectors are also popular due to their superior performance. LC connectors also have lower insertion loss compared to MTRJ Connectors

    MTRJ Connectors

    Mechanical Transfer Registered Jacks are a plastic duplex structure, used for Ethernet connections.


    Mechanical Transfer Register Jack connectors are part of the small form factor connectors group, which combine two fibres into a ferrule. MTRJ connectors are mated together with the use of insertion of pins.


    Common Uses

    These are smaller than SC connectors, and offer higher density installations, lowering cost and saving space. These are only suitable for multimode installations and are commonly used for Local Area Networks, Wide Area Networks and Data centers.

    ST Fibre Optic Connectors

    ST Connectors

    ST connectors have a ferrule measurement of 2.5mm, aiding lower loss in transmission, and are designed to have a quick release bayonet.


    Straight Tip connectors (ST), were one the first Optical fibre connectors be used in the cabling installation industrial for commercial installations.


    ST vs LC Connectors

    LC Connectors are now the mostly installed fibre connectors in the industry, due to it’s smaller ferrule measurement of 1.25mm which allows for higher density installations in smaller spaces.

    SC Connectors

    SC connectors have a push-pull mechanism and a 2.5 mm ferrule.


    SC Connector best uses

    SC Connectors are best suited for the installation of multimode fibres, and offer lower light loss, and therefore higher performance.

    As the client I can only say thanks and its an amazing piece of work by all involved. Believe me that the work to coordinate this work around other issues was challenging but Wayne and ACCL were great.

    TUI / Scott Ronan

    I have had the pleasure of asking Wayne and team for advice and guidance over a number of years, and have always felt assured that all advice I have received was totally unbiased and 100% accurate.

    Ntegra Ltd / Grant Ward, Test Manager

    The Engineers were helpful and patient. They did anything and everything that was asked of them. Thanks for a very good first job.

    Leagas Delaney / Alfred Place, London

    The Engineers were punctual and courteous whilst on site. They worked professionally, always being aware of the needs of the other tradesman who were also working on this project. They were sympathetic to the needs of the school and we are very satisfied with the overall installation.

    Bishopshalt School / Evelyn Nolan

    Another professional installation by ACCL, on time and in budget!

    Bank of New York / Alan Hawley, President of IT Infrastructure

    All the people involved were extremely helpful at all times. All performed equally well in a fast-track project and responded quickly to any changes in requirements.
