Abstract
An optical fiber system that enables direct board-to-board optical communication is described. The optical fiber system does not require data transmission through the backplane and, consequently, avoids the complexity and possible communication delays that would be required if data transmissions had to go through the backplane. The optical fiber system includes a positioner that is configured to urge opposite ends of two or more optical fibers respectively toward opposed optical devices that are coupled to facing sides of adjacent printed circuit boards coupled to a common backplane. The optical fiber system may be installed and removed quickly and easily, and may be readily retrofitted into existing computer systems.

A method for positioning two or more optical fibers between opposing optical devices coupled to facing sides of adjacent and substantially parallel printed circuit boards coupled to a common backplane, the method comprising:
- applying a compressive force to each end of a flexible, resilient member having two ends and holding the two or more optical fibers in a spaced-apart, substantially planar array, the member elastically bendable into a curvable shape in response to the compressive force;
- positioning the member between the facing sides of the printed circuit boards;
- and
- releasing the member from the compressive force, such that a restoring force tends to return the member back to an original shape and urges the optical fibers toward the opposed optical devices and guides the optical fibers into alignment with the optical devices.
A method for positioning two or more optical fibers between opposing optical devices coupled to facing sides of adjacent and substantially parallel printed circuit boards coupled to a common backplane, the method comprising:
- setting a positioner into a disengaged configuration, the positioner including a receiving surface to receive a multi-fiber fiber optic cable including two or more optical fibers, two supports arms, each configured to pivotally couple to one of the opposed optical devices, and at least two support fingers connected to each support arm, the fingers of each arm configured to move apart from each other when the positioner is in the disengaged configuration;
- loading a multi-fiber fiber optic cable including the two or more optical fibers onto the positioner;
- and
- setting the positioner into an engaged configuration, wherein the fingers of each arm of the positioner are configured to interleave with the fingers of the other arm when the positioner is in the engaged configuration.
