Ribbon Optical fibers are protected inside the slots. The cable core is inner sheathed. The corrugated steel armor further covered by outer sheath provide excellent mechanical performance. Suitable for high fiber count duct and direct burial applications with good crush performance.
Wrapping Tube CableTM (WTC) consists of Fujikura's novel Spider Web RibbonsTM (SWR) which are wrapped by a water blocking tape and non-metallic side strength members embedded in the sheath. Compared to normal loose tube cable, this full dry structure ribbon cable drastically reduces the cable deployment time by eliminating the process to wipe out jelly and by mass fusion splicing just like conventional ribbon cable. WTC achieves the world's highest density of optical fiber ribbon cable and allows effective utilization of existing conduits. Suitable for lashed aerial and duct installation applications.
