Corning 24 Strand Singlemode Indoor/Outdoor Riser Fiber Optic Cable - Black (Per Foot)

Reference#: 69121
Item#: COR-024E8F-31131-29


Corning Cable Systems FREEDOM One Riser Cables are flame-retardant, UV-resistant, indoor/outdoor cables designed for aerial, duct and direct-buried applications with no need for a transition splice when entering the building. Available in fiber counts of six, 12, 18 and 24 fibers, the tight-buffered construction facilitates easier termination for low-fiber-count applications in the local area network (LAN) and eliminates need for fan-out kits.

The design features TIA-598 color-coded 900 µm TBII Buffered Fibers for easy identification, consistent stripping and direct termination. Available in 50 µm, 62.5 µm, single-mode and hybrid versions, the cable design meets ICEA S-104-696 test criteria and is also OFNR and FT-4 listed for riser and general purpose use. The small diameter and bend radius of the cable allow for easy installation in space-constrained areas while the innovative water-blocking technology is ideal for OSP applications.
