Sumitomo Electric Lightwave’s Freeform Ribbon™ Interlocking Armored Indoor Riser Central Tube Cables feature a flame retardant outer jacket, an interlocking armor which adds protection against crushing forces, and the patented 12 fiber pliable Freeform Ribbon™ constructed of 250 μm color-coded optical fibers. Freeform Ribbon™ enables high fiber density within a small cable diameter which minimizes duct space requirements. The twelve fiber ribbons may be spliced to a conventional ribbon, pliable ribbon, or non-ribbonized (single) fibers, as well as connectorization with both MPO and all industry standard connectors. The non-preferential bend axis allows for easy installation in space-constrained areas.
