Fiber ducting system
lightways is a fiber ducting/protection system for telephone company central offices and shelters and cable-TV headends. This snap-together design requires no hardware. Vertical drops can be accommodated in less than five minutes with a cut-out tool, according to the manufacturer, limiting the typical disassembly and replacement of ducting sections to drop fibers into racks. Sizes include 8, 4, 2, and 1.25 inches. All materials meet UL-94V0, and the system is halogen-free.
