A flexible cable guide and enclosure is disclosed for guiding one or more optic fiber cables between an outside of the enclosure and a moveable tray inside the enclosure on which devices terminating the one or more are mounted. A first end of the cable guide is secured to an outside of the enclosure and a second end is secured to the tray for movement therewith. The flexible cable guide ensures that the optic fiber cables transition smoothly from the outside of the enclosure to the devices.
