Sumitomo Electric Lightwave’s 4th Level™ Outdoor/Indoor OFNR Low Smoke Halogen- Free cables feature a flame retardant outer jacket and 12 fiber Pliable Ribbons constructed of 250μm color-coded optical fibers for easy fiber identification. The all-dielectric cable construction requires no grounding or bonding. 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 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).
Cable counts of 288F, 1152F and 1728F meet Construction Product Regulations (CPR) ratings for European markets.
Cable colors other than Black contain a UV inhibitor. UV inhibitors not based on carbon black are known to be less robust and will eventually break down if exposed to long term UV exposure. For long term UV exposure black cable jackets are recommended.
