Check Availability ## Crown Castle Fiber overview Crown Castle Fiber is a division of Crown Castle International, the largest provider of shared communications infrastructure in the United States. While Crown Castle is best known for their cell tower portfolio, their fiber division operates approximately 85,000 route miles of fiber concentrated in the top U.S. metropolitan markets. Crown Castle's fiber solutions are designed for organizations that need high-capacity, low-latency connectivity — particularly carriers, data centers, enterprises, and small cell deployments. Their dark fiber product gives customers complete control over their optical network, while lit services provide managed bandwidth without the complexity of operating your own optical equipment. What makes Crown Castle unique is their focus on dense metro fiber. Rather than building a nationwide long-haul network, they concentrate fiber assets in the markets where demand is highest — places like New York, Los Angeles, Dallas, Chicago, and Philadelphia. This metro-dense approach means they often have fiber closer to your building than national carriers. ## Key specifications Technical details and service parameters for Crown Castle Fiber. ### Speed Range 1 Gbps — Unlimited (dark fiber) Dedicated: Customer-defined wavelengths ### Uptime SLA 99.999% availability on dark fiber infrastructure; 99.99% on lit services ### Coverage Major metropolitan areas with dense fiber networks.
