ABSTRACT:
A multifiber optical connector for optical ribbon cable which must be essentially used in the optical line that requires a repeated connection and separation to transfer or to interrupt simultaneously optical signals with low loss by attaching to an end of the optical ribbon cable arranged in a line. In order to overcome a difficulty of production technique and to constitute a suitable net, the optical cable consists of a short circuit which must be connected for the maintenance of the optical path, in which the optical cable must be very precisely connected so as to minimize a loss. The multifiber optical connector for optical ribbon cable according to the present invention is comprised of arranging means comprising a ferrule to fix and arrange ends of both sides of multifiber optical cable for an exact connection, an arranging block for connecting section of both sides of the said ferrule to be coincided exactly and a leaf spring to act an elastic force upon the said ferrule; and connecting means comprising an adaptor, an optical cable protecting instrument and a plug in which the said arranging means are established and it connects them strongly, and which is capable of contributing to settle a period of an optical communication by early realization of a network of optical passivity in which a heart part of the optical connector, such as ferrule, arranging elements and connecting structure are embodied by using new materials and new structure and thus, commercial-viability, performance and assembling property are improved.
