Sumitomo Electric Lightwave’s 4th Level™ Outdoor/Indoor OFCR LSHF cables feature a flame retardant outer jacket and 12 fiber pliable ribbons constructed of 250um color-coded optical fibers for easy fiber identification. Interlocking armor adds protection against crushing forces. 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 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). This cable is designed for areas that require Low Smoke and Zero Halogen such as Subways systems and Tunnels.
