Abstract

An optical cable including connectors includes a plurality of waveguide layers each including a plurality of optical channels each having a first end and a second end. First and second connectors each include a plurality of electrically conductive pins, and each of the plurality of optical channels of each of the waveguides, at their first and second ends, are connected to a specified pin on each of the first and second connectors, respectively. A first optical channel connection pattern on the first connector, and a second optical channel connection pattern on the second connector. The first optical channel connection pattern on the first connector is a different pattern than the second optical channel connection pattern on the second connector in relation to a connection hole pattern which is the same for both the first and second connectors.

Claims (15)

1. An optical cable including connectors, comprising:

a first set of waveguides and at least a second set of waveguides, wherein each waveguide of the first set of waveguides and the at least the second set of waveguides includes a plurality of optical channels encased in a polymer, each of the waveguides and the optical channels having a first end and a second end;

first and second connectors each including a plurality of electrically conductive pins, each of the plurality of optical channels of each of the waveguides, at their first and second ends, being connected to a specified pin on each of the first and second connectors, respectively, wherein a first central portion of each of the waveguides in the first set of waveguides is displaced in a first direction away from a substantially central longitudinal axis of the waveguides in the first set of waveguides, wherein the substantially central longitudinal axis traverses a substantially central bifurcation line of the first and second connectors connected to each of the plurality of optical channels at opposite ends of the waveguides in the first set of waveguides, and a second central portion of each of the waveguides in the at least the second set of waveguides is displaced in a second direction away from the substantially central longitudinal axis of the waveguides;

a first optical channel connection pattern on the first connector being formed by the first ends of the optical channels of the waveguides in the first set of waveguides and the at least the second set of waveguides being connected to the first connector;

a second optical channel connection pattern on the second connector being formed by the second ends of the optical channels of the waveguides in the first set of waveguides and the at least the second set of waveguides being connected to the second connector; and

the first optical channel connection pattern on the first connector being a different pattern than the second optical channel connection pattern on the second connector in relation to a connection hole pattern which is the same for both the first and second connectors wherein the connection hole pattern is formed from a plurality of holes in each of the first and second connectors wherein the plurality of holes house the electrically conductive pins, respectively.

2. The optical cable of claim 1 , wherein the first and second connectors include rows and columns of connection holes.

3. The optical cable of claim 2 , wherein the first and second connection patterns include respective first and second orders of the columns for the first and second connectors.

4. The optical cable of claim 1 , wherein the first set of waveguides have specified optical channels connected to a plurality of pins in a column of the first connector and a sequential plurality of rows of the first connector, the first set of waveguides having the specified optical fibers connected to a plurality of pins in a corresponding column of the second connector and a sequential plurality of rows in the second connector, and

the at least the second set of waveguides having optical channels connected to a plurality of pins in the column of the first connector in a different sequential plurality of rows than the first connector, and the at least the second set of waveguides having the optical waveguide channels connected to a plurality of pins in the corresponding column of the second connector in a different sequential plurality of rows than the second connector of the first set of waveguides.

5. The optical cable of claim 1 , wherein the first set of waveguides have specified optical channels at the first end connected to a plurality of pins in a column of the first connector in a first specified order of rows, the first set of waveguides having the specified optical waveguide channels at the second end connected to a corresponding column of the second connector in a second specified order of rows different from the first specified order.

6. The optical cable of claim 1 , wherein each of the first and second central portions of the waveguides of the first set of waveguides and the at least the second set of waveguides are laterally displaced in mirror image relation to each other.

7. The optical cable of claim 1 , wherein the first optical channel connection pattern on the first connector corresponds to a connection hole pattern on the first connector, and the second optical channel connection pattern on the second connector corresponds to a different connection hole pattern on the second connector, such that a first end of a waveguide from a first set of waveguides and at least the second set of the waveguides is connected to a column of first connection holes on the first connector having a spatial column placement on the first connector, and a second end of the waveguide from a first set of waveguides and at least the second set of the waveguides is connected to a column of second connection holes on the second connector having a spatial column placement different from the first connector wherein the first and second connector hole patterns are identical.

8. The optical cable of claim 1 , wherein the first and second connectors include rows and columns of connection holes, and the first and second connection patterns include respective first and second orders of the columns for the first and second connectors, wherein the first optical channel connection pattern on the first connector includes the first ends of a first optical channel being connected to the holes of a first column on the first connector, and the second optical channel connection pattern on the second connector including the second ends of the first optical channel being connected to the holes of a second column on the second connector, wherein the first column on the first connector and the second column on the second connector are in a different spatial relation with respect to the connection hole pattern which is the same for both the first and second connectors.

9. The optical cable of claim 8 , wherein the second column of the second connector is spatially displaced by one column in the connection hole pattern with respect to the connection hole pattern on the first connector.
