1. An optical fiber connector plug for mating with an optical fiber receptacle to form an optical fiber connection, said optical fiber connector plug comprising:

  • a connecting portion comprising;

    a containment body including a rear entry formed therein at a first end thereof and a first fiber stub exit opening to a first fiber stub channel, said first fiber stub exit being parallel to a second fiber stub exit opening to a second fiber stub channel, said first and second fiber stub exits being formed at a second end opposite said first end of said containment body;

    a holder for permanent retention of a stripped, cleaved and polished end portion of at least one optical fiber, said holder having a size for insertion into said rear entry of said containment body;

    a first crimp element having an open-ended bore coaxial with said first fiber stub channel, said open-ended bore having a front end opening to said first fiber stub channel, said open-ended bore further having a rear end to receive the stripped, cleaved and polished end portion of the at least one optical fiber;

    a second crimp element having an open-ended bore coaxial with said second fiber stub channel, said open-ended bore of said second crimp element having a front end opening to said second fiber stub channel, said open-ended bore of said second crimp element further having a rear end to receive the stripped, cleaved and polished end portion of the at least one optical fiber;

    a first fiber stub inserted along said first fiber stub channel to enter said first crimp element;

    a second fiber stub inserted along said second fiber stub channel to enter said second crimp element;

    a molded top attached to said containment body said molded top including a substantially rectangular opening located between a first end portion and an opposing second end portion; and

    a compression element positioned in said substantially rectangular opening for movement between a first position and a second position to apply force to each of said first crimp element and said second crimp element, said compression element occupying said first position for width adjustment of each said bore, of said first crimp element and said second crimp element, to receive the stripped, cleaved and polished end portion of the at least one optical fiber, said compression element occupying said second position for splicing said first fiber stub with the stripped, cleaved and polished end portion of the at least one optical fiber in said first crimp element and splicing said second fiber stub with the stripped, cleaved and polished end portion of the at least one optical fiber in said second crimp element;

    a biasing element having a first resilient finger parallel with a second resilient finger, said resilient fingers restricting movement of said first fiber stub and said second fiber stub after mating of said connector plug with said optical fiber receptacle;

    a bend relief boot having an opening therethrough to enclose said first end of said containment body and said first end portion of said molded top; and

    a shroud for releasable engagement over said second end of said containment body and said opposing second end portion of said molded top.
