Abstract

A fiber optic cable guide may have an elongated base member that is curved along at least a portion of its length to define and limit the amount of curvature to be applied to a portion of a fiber optic cable while also defining the angular offset applied to the cable. The guide may be releasably attachable to a cable, and may include a cable retention member at each end of the base member that retains the cable with the guide.
