Micro Fiber Cable Installations
MD is designed for installation into new or existing conduits to maximize conduit capacity. Mini ducts are used to sub-divide 3/4″ through 2″ I.D. conduits facilitating future installation of additional micro cables. The internal rib profile, in combination with our permanent factory lubrication process, provides for optimum productivity by reducing friction between the micro cable and the duct. MD system reduces “Last Mile” costs while optimizing system flexibility for future fiber installations.
