  • Fiber optic cable mechanical joint connection

    Fiber optic cable mechanical joint connection

    Semi-permanent connections can be made with mechanical splices, which are relatively simple alignment devices holding the fiber ends together. Typically, some index-matching gel or an epoxy is used for reducing reflection losses. Examples are fiber lasers and systems for optical fiber communications. Mechanical splices are used to create permanent joints between two fibers by holding the fibers in an alignment fixture and reducing loss and reflectance with a transparent gel or optical adhesive between the fibers that matches the optical properties of the glass. Either joining method must have three primary characteristics. Optical fibers can be joined together, such that light is efficiently transferred from one fiber to another. That is usually done for permanent connections, but it. A field installable factory pre-polished connector that utilizes the proven technology of mechanical splices to provide customizable connectivity solutions.
