Freeform Ribbon® Flexible Indoor Riser Central Tube Cables

Sumitomo Electric Lightwave’s Freeform Ribbon® Flexible Indoor Riser Central Tube Cables feature a flame retardant outer jacket and 12 fiber Freeform Ribbon® constructed of 250 & 200 μm color-coded optical fibers for easy fiber identification. The all-dielectric cable construction requires no grounding or bonding and meets OFNR and CSA FT4 specifications. Additionally, the Freeform Ribbon® allows for dense fiber packing and a small cable diameter with a non-preferential bend axis thereby increasing density in space-constrained applications. Sumitomo Electric’s patented Freeform Ribbon® construction is designed to both pack densely in small form factor cables while still being capable to transform quickly, by hand ONLY, to splice-ready form similar to standard ribbon for fast and easy 12 fiber ribbon splicing (for both in-line and fusion splice-on connector splicing applications).
