ROI Calculation
Methodology
Operators calculate return on investment (ROI) by comparing the total financial benefits of F5.5G and 50G PON deployment to the combined CAPEX and OPEX. The ROI formula is:
ROI = (Total Revenue Generated – Total Costs) / Total Costs × 100%
To estimate total revenue, operators consider new service adoption rates, ARPU growth, and additional business opportunities enabled by the upgraded network. Total costs include both initial infrastructure investments and ongoing operational expenses. Operators should also factor in market dynamics, such as user demand for high-speed fiber and the competitive landscape. A higher ROI indicates a more successful deployment and faster payback period.
Note: Operators should regularly update their ROI calculations as market conditions and user behaviors change. This practice ensures that business strategies remain aligned with actual network performance and market growth.
Sample Calculation
Consider an operator in a large urban market planning to upgrade from 10G PON to 50G PON. The initial CAPEX for new OLTs, splitters, and fiber extensions totals $5 million. Annual OPEX, including energy and maintenance, is $500,000. The upgraded network enables the operator to launch premium broadband services, increasing ARPU by $10 per user per month. With 20,000 new and existing users adopting the service, annual revenue rises by $2.4 million.
Total Costs (Year 1): $5,000,000 (CAPEX) + $500,000 (OPEX) = $5,500,000
Total Revenue (Year 1): $2,400,000
Using the ROI formula:
ROI = ($2,400,000 – $5,500,000) / $5,500,000 × 100% = -56.4%
In this scenario, the operator does not achieve a positive ROI in the first year. However, by the third year, cumulative revenue reaches $7.2 million, while total costs rise to $7 million. The ROI after three years becomes:
ROI = ($7,200,000 – $7,000,000) / $7,000,000 × 100% = 2.86%
This example shows that ROI improves over time as more users adopt premium services and operational efficiencies increase. Operators in fast-growing markets with high demand for fiber-based services can expect a shorter payback period and higher long-term returns.
Tip: Operators should tailor their ROI models to reflect local market conditions, user growth rates, and infrastructure reuse opportunities. Accurate forecasting helps guide investment decisions and supports sustainable network growth.
