Abstract: A method and apparatus are disclosed that permit multi-directional fiber optic connections to a device. The multi-directional aspect of the fiber optic connections permit the connections to be aligned closely with the direction of travel of the fiber optic cables that interface with the device. Closely aligning the fiber optic connections on the device with the fiber optic cables' direction of travel maximizes the bend radius of the fiber optic cable near the point of connection or eliminates the bend altogether and reduces the likelihood of a broken fiber or signal attenuation.
