The Fiber Journey
How Vast installs your business fiber, step by step
Every dedicated fiber internet connection Vast Networks delivers follows the same disciplined, seven-step process — from the moment your order lands to the day your circuit is lit. Because we designed, built, and own more than 5,000 route miles of private underground fiber across California, we control every stage of the fiber-optic installation in-house. Here is exactly how we turn a service request into SLA-backed, low-latency enterprise connectivity.
01Step 01
Order — requesting business fiber internet
Your fiber journey begins the moment your order reaches our team. We capture your service address, the Dedicated Internet Access (DIA) speed you need — anywhere from 100 Mbps to 400/800 Gbps — and the workloads driving your bandwidth, from cloud applications and VoIP to off-site backup and multi-site connectivity.
Our California-based engineers immediately check your proximity to our privately owned fiber backbone, confirm whether your building is on-net or near-net, and prepare a transparent quote with a realistic installation timeline. No shared-bandwidth surprises, no guesswork.

02Step 02
Site verification — confirming fiber reaches your premises
A field technician performs an on-site fiber survey to verify that fiber-optic cable can reach your premises cleanly. We inspect building entry points, the minimum point of entry (MPOE), risers, conduit, and the meet-me room, then map the physical path from the nearest fiber access point to your equipment.
This fiber feasibility study removes risk before construction starts. By validating right-of-way access and the last-mile route early, we keep your dedicated fiber installation on schedule and on budget.

Engineering — designing your dedicated fiber route
Our network engineers design the exact fiber-optic route — cable paths, conduit, handholes, splice points, and equipment placement — to deliver carrier-grade, low-latency performance. Every circuit is engineered to MEF-aligned standards with diverse, redundant routing for resilience.
We model capacity from day one so your connection scales from megabits to hundreds of gigabits without a forklift upgrade. The result is a documented, build-ready design tailored to your bandwidth, uptime, and SLA requirements.

Permitting — securing right-of-way and approvals
Before any ground is broken, Vast secures the permits and right-of-way (ROW) approvals required for fully compliant fiber construction. We coordinate with municipalities, utilities, departments of transportation, railroads, and property owners to obtain encroachment permits and pole or conduit agreements.
Managing permitting in-house keeps your fiber-optic build compliant and avoids the costly delays that stall most network projects. We handle the paperwork and agency coordination so your enterprise connectivity stays on track.

Construction — building underground fiber to your door
Construction crews break ground using directional boring, micro-trenching, and conduit placement to run protected underground fiber to your location. Buried plant resists weather, construction accidents, and the outages that plague aerial connections.
We pull fiber-optic cable through the new conduit, set handholes and vaults, and fully restore the site — extending our private California fiber backbone the final mile to your building.

Fiber splicing — fusing your connection into the network
Certified technicians perform fusion splicing to join the glass strands with sub-decibel precision, connecting your last-mile fiber into the Vast DWDM optical core. Every splice is OTDR-tested to verify low insertion loss and pristine optical performance.
This precision fiber-optic splicing is what guarantees the signal integrity behind your SLA — minimizing latency and packet loss across every wavelength on your dedicated circuit.

07Step 07
Networking — provisioning, testing, and going live
In the final step we provision your circuit, configure IPv4 and IPv6 addressing and routing — BGP, OSPF, or static — and run end-to-end throughput and latency testing. Once your connection passes carrier-class acceptance testing, your fiber service is lit.
Your dedicated fiber goes live, monitored 24/7 by our local Network Operations Center, backed by a financially guaranteed SLA, and ready to scale on demand. Welcome to the fiber era.

Fiber installation process FAQs
Common questions about how dedicated fiber internet is surveyed, engineered, permitted,
built, spliced, and provisioned across California.
How long does business fiber internet installation take?
It depends on whether your building is on-net or near-net. Where Vast fiber is already in place, activation can be fast. New builds move through site verification, engineering, permitting, underground construction, fiber splicing, and provisioning — and we confirm a realistic timeline with your quote so there are no surprises.
What is a fiber site survey?
A fiber site survey, or feasibility study, is an on-site assessment where our field technician verifies that fiber-optic cable can reach your premises. We inspect entry points, the MPOE, conduit, and risers, and map the last-mile route before any construction begins — keeping your installation on schedule and on budget.
Do I need permits for fiber construction?
Yes. Underground fiber construction typically requires encroachment permits and right-of-way approvals from municipalities, utilities, and departments of transportation. Vast manages all permitting and agency coordination in-house so your fiber-optic build stays fully compliant and avoids costly delays.
What is fiber splicing and why does it matter?
Fiber splicing is the process of fusing optical glass strands together to join your last-mile fiber into the network. Our technicians use fusion splicing with sub-decibel precision and OTDR testing to ensure low insertion loss — protecting the low-latency, low-packet-loss performance guaranteed by your SLA.
How do you run fiber to my building — trenching or boring?
We use directional boring, micro-trenching, and conduit placement to install protected underground fiber. Buried plant is far more resilient than aerial fiber, resisting weather and accidental damage, which is why our private California backbone is engineered underground end to end.
What happens when my dedicated fiber circuit goes live?
After provisioning, IP routing configuration, and carrier-class acceptance testing, your dedicated fiber service is lit and monitored around the clock by our 24/7 Network Operations Center. It is backed by a financially guaranteed SLA and built to scale from 100 Mbps to 400/800 Gbps on demand.
