Introduction
The 7632-X 3 Inches Textile Fabric Innerduct is the backbone for high-performance OSP/ISP networks requiring unmatched durability and flexibility. Its triple-layer reinforced fabric withstands harsh conditions—moisture, abrasion, and extreme temperatures (-50°F to 200°F)—while the split-tube design enables tool-free, rapid cable installation. Ideal for aerial, buried, or riser deployments, this duct reduces labor costs by 35% and simplifies future upgrades. Backed by a 10-year warranty and Telcordia GR-20 certification, the 7632-X ensures long-term reliability and scalability for 10+ fiber expansions.
