Abstract
Abstract A combination of distribution frame and optical connector holders receivable in the frame provided with an electrical circuit which permits both ends of a chosen optical fiber patch cord to be located quickly. The patch cords have electrical conductors in addition to optical fibers. After one end of the chosen patch cord is located in one holder, an electrical current is passed along one circuit including the patch cord to result in an indicator lamp being lit on the other holder holding the other end of the chosen patch cord. Using a different circuit, the other end of the chosen patch cord is distinguished from all patch cord ends in the other holder.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
A distribution frame and optical connector holder combination comprising: distribution frame means for receiving a plurality of connector holders; a plurality of optical connector holders receivable within the frame means, the holders having mounting means for positioning a plurality of optical connectors which, when mounted, have first ends which, in different holders, are for selective optical interconnection by patch cords each extending from one of said connectors to another of said connectors, and second ends for connection to optical fibers in the holders; and electrical test means which, when each patch cord interconnects selected first ends of associated connectors and each of said patch cords is provided with an electrical conductor electrically connected to its associated connectors, is operational to locate both associated connectors of a particular patch cord, the test means being connectable to a first associated connector of the conductor of the particular patch cord to pass an electrical current through an electrical circuit arrangement including the first associated connector, the conductor of the particular patch cord and the second associated connector of the conductor of the particular patch cord, to provide an indication of the location of the second associated connector.
Claim 2
Dependent Claim
194 words
A distribution frame and optical connector holder combination comprising: distribution frame means for receiving a plurality of connector holders; a plurality of optical connector holders receivable within the frame means, the holders having mounting means for positioning a plurality of optical connectors which, when mounted, have first ends which, in different holders, are for selective optical interconnection by patch cords each extending from one of said connectors to another of said connectors, and second ends for connection to optical fibers in the holders; and electrical test means which, when each patch cord interconnects selected first ends of associated connectors and each of said patch cords is provided with an electrical conductor electrically connected to its associated connectors, is operational to locate both associated connectors of a particular patch cord, the test means being connectable to a first associated connector of the conductor of the particular patch cord to pass an electrical current through an electrical circuit arrangement including the first associated connector, the conductor of the particular patch cord and the second associated connector of the conductor of the particular patch cord, to provide an indication of the location of the second associated connector.
Claim 3
Dependent Claim
127 words
A combination according to claim 1 wherein the holders are movable into and out of operational positions within the frame means; each holder which has mounting means for positioning associated connectors also has signalling means of the test means and a conductor arrangement extending from the signalling means to the mounting means; and the frame means has a frame conductor means of the test means, the signalling means of each holder being electrically connected to the frame conductor means with the holder in its operative position whereby, upon passage of a current from the first associated connector to the second associated connector, the holder carrying the second associated connector is identified by current passing through the appropriate conductor arrangement and signalling means into the frame conductor means.
Claim 4
Dependent Claim
175 words
A combination according to claim 1 wherein the holders are movable into and out of operational positions within the frame means and the mounting means in each holder are inaccessible in the operative position of the holder and are accessible in a position of the holder removed from the operative position; and wherein each holder has signalling means of the test means and a conductor arrangement extending from the signalling means to the mounting means; and the frame means has frame conductor means of the test means, the conductor and signalling means of each holder being electrically connected to the frame conductor means with the holder in its operative position whereby, when the test means is connected to the first associated connector in an accessible mounting means and the holder carrying the second associated connector is in its operative position, then upon passage of current to the first asociated connector, the holder with the second associated connector is identified by current passing through the appropriate conductor arrangement and signalling means into the frame conductor means.
Claim 5
Dependent Claim
20 words
A combination according to either of claims 2 and 3 wherein the signalling means comprises a light emitting signalling member.
Claim 6
Dependent Claim
114 words
A combination according to claim 3 wherein the test means comprises a plurality of electrical probes; one of the probes being provided for electrical connection to the accessible first associated connector to identify the holder having the second associated connector; and with the holder having the second associated connector conductor moved out of its operative position to render its mounting means accessible, another of the probes is provided for connection selectively to connectors mounted in the holder having the second associated connector, the test means also including an indicating means to be actuated upon the other probe being connected to the second associated connector so as to complete a circuit including the indicating means.
Claim 7
Dependent Claim
55 words
A combination according to claim 5 wherein the frame conductor means comprises a ground conductor and the connector arrangement of each holder provides for electrically connecting connectors to be mounted in parallel relationship with one another in the holder, the conductor arrangement also allowing for passage of current in one direction only through each connector.
Claim 8
Dependent Claim
32 words
A combination according to claim 6 wherein the conductor arrangement of each holder comprises a diode associated with each mounting position, each diode allowing for passage of current in one direction only.
Claim 9
Dependent Claim
89 words
A combination according to claim 6 wherein the connector arrangement of each holder is provided with in-parallel circuit lines extending one to each connector mounting means and each holder is also provided with connector mounts of the mounting means, one mount of each mounting means, and each mount carries an optical connector with a bridging conductor extending from the connector to a corresponding circuit line, and the means to allow for passage of current in one direction only is carried by each mount as part of the bridging conductor.
Claim 10
Dependent Claim
27 words
A combination according to claim 5 provided with junction box means carried by the frame means and the probes are electrically connected to the junction box means.
Claim 11
Dependent Claim
38 words
A combination according to claim 9 wherein the frame means comprises a plurality of distribution frames and the junction box means comprises a junction box carried by each distribution frame, each junction box comprises two probes extending therefrom.
