## Abstract

A double flexible optical circuit includes: a flexible substrate supporting a plurality of optical fibers; a first connector terminating the optical fibers at a first end of the double flexible optical circuit; and a second connector terminating the optical fibers at a second end of the double flexible optical circuit. Each of the optical fibers is positioned in one of a plurality of separate extensions formed by the flexible substrate as the optical fibers extend from the first connector to the second connector. The first and second connectors are configured to be tested when the first and second connectors are connected through the double flexible optical circuit. The double flexible optical circuit is configured to be divided in half once the testing is complete to form two separate flexible optical circuits.

## Claims

### Claim 1

A fixture for a flexible optical circuit, the fixture comprising:
a main body having a base defining a plurality of holes sized to receive ferrules and a plurality of channels positioned to receive extensions of the flexible optical circuit, with the extensions of the flexible optical circuit being terminated by the ferrules;
the base being sized to receive a substrate of the flexible optical circuit, the substrate being coupled to the extensions of the flexible optical circuit; and
a clamp member positioned to hold the ferrules in place within the holes during assembly of the flexible optical circuit.

### Claim 2 (depends on 1)

The fixture of claim 1, further comprising a member sized to hold a connector positioned at an end of the flexible optical circuit opposite to that of the extensions.
