Product offeringCore offering
Crown Castle's Fiber Solutions business provides fiber-based connectivity services, including dark fiber leases, wavelength services, small cell backhaul, and private fiber networks to carriers, enterprises, data centers, and government customers. The business operates approximately 90,000 metro-dense route miles of fiber across major U.S. metropolitan markets.
Product overview
Zayo operates a platform-plus-modules architecture for fiber and network infrastructure. The core platform is built on an extensive physical fiber network spanning over 240,000 route miles and 34 million fiber miles across North America and Europe. Crown Castle's Fiber Solutions business was acquired in May 2026, adding 90,000 metro-dense route miles. The product portfolio is organized into four layers: (1) Fiber & Transport — Dark Fiber, Private Networks, Wavelengths, and Wireless Infrastructure providing the physical connectivity substrate; (2) Network Connectivity — CloudLink, DDoS Protection, Dedicated Internet Access, DynamicLink, Ethernet, IP Transit, STARLINK, and WANs delivering lit services and cloud integration; (3) Managed Edge — Managed SD-WAN, SASE, and Managed Firewall providing security and network optimization; and (4) Voice & Collaboration — Zayo SIP Solutions and Zayo UC+ (integrating RingCentral) delivering communications services. ENA by Zayo extends the platform to K-12 education sectors.

Products and services
- Dark fiber services Leased unlit optical fiber pairs on metro routes, allowing carriers and enterprises to self-provision their own optical transport equipment. Targeted at buyers that need dedicated, scalable capacity over predictable long-term contracts.
- Wavelength services High-capacity, lit optical wavelength transport between locations. Designed for customers requiring turn-up of dedicated high-bandwidth links (e.g., 10G/100G/400G-equivalent) without operating their own optical line systems.
- Small cell backhaul Fiber backhaul connectivity for outdoor small cell and 5G densification nodes in urban venues. Sold to mobile network operators and neutral-host deployers that need fiber-deep connectivity in metro corridors.
- Private fiber networks Dedicated private fiber network connectivity for enterprises, data centers, and government agencies requiring secure, isolated transport between sites.
- Metro fiber connectivity Lit managed connectivity (Ethernet, IP, and optical services) delivered over the metro-dense fiber footprint for enterprise and carrier customers across major U.S. markets.

Crown Castle’s Fiber Solutions business competitors and assessment
Company assessmentDirect peers
- Cogent Communications: Cogent is a wholesale-focused IP transit and fiber operator serving carriers, enterprises, and content providers globally. Closely comparable business model in dedicated fiber and wavelength services to similar enterprise/carrier customers.
- ExteNet Systems: ExteNet is a Crown Castle-owned (via sale from DigitalBridge) provider of fiber and small-cell infrastructure for wireless carriers and enterprises. Directly comparable in the small-cell densification and fiber-to-the-tower use case that Crown Castle Fiber Solutions served.
- Zayo Group: Zayo is the acquirer of Crown Castle Fiber Solutions and operates the most directly comparable U.S. metro and long-haul fiber footprint. Both provide dark fiber, wavelengths, and managed services to carriers, enterprises, and hyperscalers under similar IRU/lease economics.
- FiberLight: FiberLight operates metro dark fiber networks across major U.S. cities serving carriers, enterprises, and data centers. Highly comparable in scale and customer mix to Crown Castle's Fiber Solutions metro-dense footprint.
- Lightpath (Crown Castle subsidiary): Lightpath is the remaining Crown Castle-owned fiber business focused on enterprise customers in the Northeast U.S. Historically part of the same Crown Castle Fiber Solutions portfolio and offers nearly identical enterprise metro fiber services.
Broad incumbents
- AT&T Business: AT&T Business offers a national fiber backbone plus metro connectivity for enterprises and carriers. While broader in scope, it directly competes for wholesale IRU, wavelength, and enterprise managed services contracts.
- Verizon Business: Verizon operates one of the largest U.S. fiber footprints and provides enterprise dark fiber, wavelength, and managed services. Competes directly for large enterprise and carrier wholesale contracts while also serving its own wireless network needs.
- Lumen Technologies: Lumen is a large incumbent U.S. fiber and managed services carrier with significant metro and long-haul assets, including the former Level 3 footprint. Competes head-to-head for enterprise, carrier, and hyperscale fiber contracts.
Regional players
- Frontier Communications: Frontier operates a significant U.S. fiber footprint with both residential and enterprise/business services. Comparable as a fiber-based service provider to enterprises and carriers, though more weighted to retail broadband than pure wholesale.
Emerging players
- Bandwidth IG: Bandwidth IG is a fast-growing metro dark fiber provider focused on hyperscale data center connectivity in U.S. tier-2 and tier-3 markets. Overlaps with Crown Castle Fiber Solutions on hyperscale DCI and enterprise dark fiber.
