Sumitomo Electric Lightwave’s Freeform Ribbon™ Indoor Riser Rated cables feature a flame retardant outer jacket and 12 fiber Freeform Ribbon™ constructed of 250μm color-coded optical fibers for easy fiber identification. The cable meets UL 1666 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). Interlocking armor adds protection against crushing forces. Flexible dielectric strength members within the cable core provide mechanical durability within a flame retardant jacket and the non-preferential bend axis allows for easy installation in space constrained areas. This riser rated cable meets or exceeds UL1666, OFNR, and CSA FT4 approvals and listings.
