First Claim
Patent Images
1. A duplex optical fiber connector for terminating two optical fibers of a cable and being adapted to be joined to a polarized receptacle, said connector comprising:
- an exterior shape corresponding to the shape of an opening of the receptacle, said connector being insertable into said opening along an axis of said receptacle;
an axially extending channel having a width corresponding to a receptacle mating configuration; and
a keying element in said channel blocking said width of said channel, said keying element having a recess, said keying element being movable transverse to said axis so that said recess may be positioned toward one side of said channel for receiving a rib of said receptacle when said rib is positioned toward said one side of said channel to be received in said recess upon said connector being axially inserted in said receptacle opening.

Abstract
A duplex optical fiber connector terminates two single or multi-mode optical fibers of a cable and is adapted to be joined to a receptacle being polarized correspondingly to a keying element of the connector. The keying element is slidable into multiple positions so that a recess in the keying element mates with a correspondingly positioned rib of a receptacle. The recess of the keying element is positioned within a channel axially extending on the connector exterior body.

17. A duplex optical fiber connector for terminating two optical fibers of a cable and being adapted to be joined to a polarized receptacle, said duplex connector comprising:
-
an exterior shape corresponding to an opening of the receptacle for being insertable into said receptacle along an axis of said receptacle; and means for polarizing said connector whereby said connector is insertable only into correspondingly configured receptacles having an inwardly protruding rib which corresponds with a position of said means for polarizing, said means for polarizing being fixedly attached to said connector wherein said means for polarizing is transversely slidable to said axis. - View Dependent Claims (18, 19)

20. A duplex optical fiber connector for terminating two optical fibers of a cable and being adapted to be joined to a receptacle, said duplex connector comprising:
-
an exterior shape corresponding to the shape of an opening of the receptacle, said connector being insertable into said opening along an axis of the receptacle; an axially extending channel having a width corresponding to a receptacle mating configuration, wherein said width of said channel is greater than the width of a rib of said receptacle; a keying element in said channel blocking said width of said channel, said keying element having a recess, said keying element being slidably moveable transverse to said axis so that said recess may be positioned toward one side of said channel for receiving said rib of said receptacle when said rib is positioned toward said one side of said channel to be received in said recess upon said connector being axially inserted in said receptacle opening, whereby said connector permits insertion of multiple configurations of said receptacle, said keying element having an exterior surface which is substantially flush with the exterior surface of said connector and said exterior surface of said keying element having multiple ridges whereby said keying element is easily gripped by a fingertip, said keying element having a detent to frictionally engage a ridge of the connector body surface abutting said keying element, said detent holding said keying element stationary within said connector body, said keying element in a stationary configuration corresponding to said rib of said receptacle; and means for identifying the position to which said keying element has been placed in correspondence with a corresponding receptacle configuration wherein said connector has letters marked thereon and a corresponding mark on said keying element whereby the movement of said keying element aligns said mark with the corresponding letter signifying the mating configuration which will accept said corresponding receptacle.
