Indoor/Outdoor Tight Buffered Riser

Drybit Cable

Indoor/Outdoor Tight Buffered Riser has a UV resistant jacket and is REACH and RoHS 2 compliant. All multimode and singlemode cables (except OM1) utilize bend-insensitive optical fibers. Dry, super absorbent polymers (SAPs) eliminate water migration in cable interstices and 900um buffered design is utilized for easy termination. Indoor/Outdoor Tight Buffered (Riser) has color coded fibers for easy identification. Cables with fiber counts of 2 to 144 are available. Fibers are segregated into 12-fiber bundles identified by color-code binders. Suitable for lashed aerial, duct, underground conduit and indoor riser environments. Supported applications include gigabit, 10 gigabit and 40 gigabit Ethernet. Made in USA. Proterial Cable America is proud to utilize Corning Optical Fiber as our standard optic fiber.
