Abstract
A method and system of managing slack in fiber optic cables connected to a circuit board is provided. A fiber optic cable is supported at a point between and not colinear with the two points to which it is attached to the circuit board. The fiber optic cables are preferably supported a vertical distance above the circuit board each with a plurality of points of support on a radius guide, preferably two radius guides. The radius guides each have a leading edge and a trailing edge for supporting the cable and a curved central portion therebetween around which the cable is bent. The cables are preferably tensioned between at least two of the points of support so that cables of differing lengths are taut to prevent movement during shipping or to prevent vibration that would otherwise be caused by air flow over the circuit board.
