  • Adaptor for an optical cable terminal
    Patent number: 6524015
    Abstract: An adaptor for an optical cable terminal consists of an outer tube that contains an interior optical cable and is able to be used with a toslink socket provided in a household appliance, a clip contained in the outer tube, and an inner tube contained also in the outer tube.
