ALTOS® Loose Tube Fiber Optic Cables

ALTOS® Loose Tube Fiber Optic Cables

Corning’s extensive ALTOS® loose tube fiber optic cable portfolio offers reliable, high-speed data transmission in duct, buried, or aerial outdoor applications. The cables are high-density, lightweight, and durable for easy handling and installations. ALTOS cables contain buffer tubes with either 12 or 24 single loose fibers for installer familiarity; in 24-fiber tube options, the second set of 12 fibers is marked for quick identification and separation. Improved outer jacket marking allows for abrasion resistance and includes highly visible key cable specifications for faster field reference. FastAccess® technology options provide simpler, safer, and faster cable jacket removal and buffer tube access.

The new high-density ALTOS HD cable with binderless FastAccess technology features 24 fibers per buffer tube in a compact yet flexible design, offering reduced outer diameter, weight, and carbon footprint compared to comparable legacy cables. An available Universal Routing Kit 24F enables quick separation of fibers into 2 x 12 fiber sets with a furcation tube that protects the fibers from sharp edges in closures and cassettes.
