3M™ Cable Transition Boxes (CTBs) are used in Fiber to the Home networks to transition from outdoor to indoor cable and are often found on the exterior of single-family homes or Multi-Dwelling Units (MDUs).
Network providers often elect to use an indoor Optical Network Terminal (ONT) to house the electronics that support the fiber optic services. The indoor drop cable is spliced or terminated to the outside plant distribution cable inside the cable transition box. It is then fed through the exterior wall of the building directly to the home or living unit ONT or a wall outlet near the ONT. 3M™ Cable Transition Boxes are small and discrete, preserving building aesthetics and incorporate our 3M connectivity products, 3M™ Fibrlok™ splices and 3M™ No Polish Connectors.
