Building differently from the ground up
Most networks are assembled over time, layered with mismatched parts and incremental upgrades. Lightpath is built differently. We own and engineer our fiber from the physical layer up, so routes are built for the traffic they carry: direct paths where latency matters and diverse paths where uptime does. That means fewer unknowns, fewer dependencies and a network that performs predictably under pressure.
Across dense metro fiber and high-capacity optical transport, every mile we build is engineered to support the workloads organizations rely on today and the ones they’re planning for next.
- All-fiber routes expanding into high-density markets
- End-to-end control of the physical layer across our footprint
- Line-side optical capacity scaling to 800 Gbps and beyond
- On-net access to data centers, cloud providers and landing stations
- Route diversity where you need it. Primary and protected paths kept physically separate.
Built for direct access to the infrastructure your network depends on
Modern networks don’t operate in isolation. They connect data centers, cloud platforms and global ecosystems that require consistent, high-performance infrastructure, allowing your data to move through the environments that matter on routes designed to get it there efficiently.
The Lightpath network spans more than 12,100 route miles and 17,500+ service locations across 11 major US metro markets, with direct, on-net connectivity into 190+ data centers and eight subsea cable landing stations.
What this enables:
- Direct data center interconnection
- Direct cloud access with optimized routing
- High-capacity transport between regional networks and major carrier and cloud ecosystems
- Reduced latency through more direct physical paths
Built where performance matters most
The Lightpath network spans some of the most data-intensive regions in the country, with dense fiber routes designed to connect enterprises, data centers and critical infrastructure hubs. Each market is built on the same core tenet: a purpose-built network delivers the digital ecosystems your business depends on, when and where you need them.
