About this model
A fiber-to-the-premises (FTTP) network model projects the deployment of broadband infrastructure to 100,000 homes over seven years, with residential subscribers ramping from zero to 30,000+ through a 35% penetration rate on the addressable base. Revenue comes from residential broadband subscriptions ($60/month, with 3% CPI-linked inflation), enterprise services ($500/month per dedicated lease line), and installation fees ($100 per new connection). The network build capex is $650 per home passed (cost per home passed, CPHP) for the fiber and passive infrastructure, plus $250 per connection (cost per connected, CPHC) for customer drop and activation.
The model tracks the build schedule (homes passed) and the subscription ramp (homes ready for service, with a one-year lag post-build). Churn is modeled at 1.2% monthly (effective ~7-year customer lifetime). Operating expenses include IP transit and interconnect ($3% of revenue), network operations and maintenance ($3% of revenue), sales and marketing ($200 per gross new subscriber), staff ($15% of revenue at maturity), and corporate overhead ($15% of revenue). The network reaches EBITDA-positive in Year 4–5 as the subscriber base scales and fixed costs are diluted.
Capital intensity is brutal in early years (capex peaks at 200%+ of revenue during the build phase). The model is financed with $50 million debt at 7.5% and $60 million sponsor equity. This template is suitable for infrastructure funds, PE investors, and regional broadband companies evaluating FTTP network deployments.

Frequently asked
What is a fibre network deployment model?+
A project finance model that forecasts network capex by segment, subscriber ramp, revenue by customer type, and payback period for a fiber broadband buildout.
What is fiber route mile capex?+
Fiber capex typically ranges $1k-3k per mile depending on terrain, rights-of-way, and labor costs. Rural areas generally cost more than urban deployments.
What is take rate or market penetration?+
The percentage of serviceable households that subscribe. Realistic rates are 20-40% in competitive markets and 40-60% in less competitive markets.
How long until a fiber network is cash-flow positive?+
Typically 8-15 years depending on capex intensity, take rate, and ARPU. Some mature networks with strong take rates generate positive cash flow sooner.
Who uses fibre network models?+
Telecom operators, regional ISPs, infrastructure investors, and broadband developers use them for buildout planning, financing, and M&A valuation.
