Freeform Ribbon™ Transit Indoor/Outdoor LSZH-NFPA130 OFCR Steel Armored Ribbon Cables

Sumitomo Electric Lightwave’s Freeform Ribbon™ Transit Indoor/Outdoor LSZH-NFPA130 OFCR Steel Armored Ribbon Cables are intended for duct and direct buried installations and feature the patented 12-fiber pliable Freeform Ribbon™ constructed of 250 μm color-coded optical fibers. These cables feature a dry water block yarn design that eliminates cable flooding gels, thereby simplifying the cleaning and blocking preparation steps associated with standard gel-filled cables. The steel-armored sheath provides a robust, rodent-resistant cable with the necessary compressive strength for direct burial applications. In addition, this cable meets NFPA130 standards, which specify fire protection and life safety requirements for underground, surface, and elevated fixed guideway transit and passenger rail systems.

Freeform Ribbon™ enables high fiber density within a small cable diameter, which in turn helps with limited duct space. The 12-fiber ribbons may be spliced to a conventional ribbon, pliable ribbon, or non-ribbonized (single) fibers, as well as connectorization with MPO and all industry-standard connectors. The non-preferential bend axis allows for easy installation in space-constrained areas.
