Corning 144 Strand FastAccess Singlemode Loose Tube Outdoor Fiber Optic Cable - Black (Per Foot)

UTILITY
The Corning Altos 144-Strand Fiber Optic Cable (Part Number: 144EU4-T4101D20) is built to meet the demanding requirements of outdoor and limited indoor installations for campus backbones and high-speed networks. This Singlemode OS2 fiber optic cable is designed to handle long-distance, high-traffic environments such as large universities, industrial parks, and enterprise-level networks. This cable simplifies installation and wiring in complex setups with 144 strands organized into color-coded tubes.

Its gel-free, water-blocked design uses water-swellable materials to protect against moisture while remaining craft-friendly. The SZ-stranded loose tube construction ensures the fibers are protected from environmental and mechanical stresses, while providing mid-span access for easier routing and splicing. The all-dielectric construction eliminates the need for bonding or grounding, and the rugged polyethylene jacket is easy to strip and durable enough for outdoor aerial and duct installations. Additionally, a ripcord allows for quick and damage-free access to the cable during setup.
