Fiber Optic Network
20+ years in communications. And we’re only getting faster with age.

Ethernet Product Sheet
Learn more about the flexible options and benefits of our Ethernet services.
We’ve built 25,000+ miles of fiber so far – and we intend to keep going. Our advanced fiber optic services connect you to virtually unlimited bandwidth and a future-proof network of up to 400 Gbps, with ultra-low latency.
Dedicated Bandwidth
It’s always your bandwidth. Not anyone else’s.
Never share your bandwidth with other businesses. You should only accept full-rate capacity as specified for both upstream and downstream. That’s the kind of service you’ll always get from us. We think this should just go without saying, but apparently some of our competitors haven’t gotten the memo quite yet.

Guaranteed Reliability
We make other lit services look like they’ve just discovered fire.

Our lit services offer you nonstop, reliable communication with ultra-low packet loss, latency, and jitter. How do we know all this? Because we built the network ourselves. We own and operate it, too.

See What Industries FirstLight Specializes In
We provide fiber-optic data, Internet, data center, cloud, unified communications, and managed services to enterprise and carrier customers throughout the Northeast and mid-Atlantic.
SCALABLE CAPACITY
Whatever speed you run your business we’ll raise you by Usain Bolt.
Are you looking to connect at 50 Gbps or 100 Gbps? Don’t even sweat it. However you want to run your business, we’ll help you run it faster.



Local Support
We treat you like a close neighbor.
Because guess what? You are one.
We’re locally managed and operated. That means if you’re in the Northeast or mid-Atlantic, we’re not just a phone call away, we’re footsteps away if you ever encounter any technical issues. Maintenance and repairs are coordinated directly from multiple Network Operations/Support Centers throughout our region. No tricks, gimmicks, or overseas support.

Greater Johnstown School District – Case Study
FirstLight’s Internet and dark fiber increased bandwidth and productivity for students and faculty at the Greater Johnstown School District in Fulton County, New York.
Reliability & Resiliency
We built our network to be bulletproof, from the ground up.
Our core network is designed to anticipate traffic problems. If one of your connections breaks down, we’ll reroute traffic via another pathway that’s on a wildly different geographical course. And if that one breaks down, we can reroute it, too. Recognizing a pattern? We hope so. It’s our life’s work to ensure your network never fails or falters.
