Improving the FTTH business case–A joint telco-utility network rollout model

Fiber to the home networks are seen as the most future proof technology to offer increasing bandwidth to customers. The publication of the Digital Agenda has put forward challenging goals for the broadband connectivity in Europe, but the rollout of next generation fixed access networks is still lagging. One of the reasons is the high initial investment cost associated with the rollout of these networks. To decrease this cost, a cooperation model between utility operators during the deployment phase is proposed in this paper. A model has been developed, in order to optimize the position of the different infrastructures in the trench and to allow for a fair allocation of the different costs incurred between all cooperating parties. The combination of these models has shown that a synergetic deployment phase of new infrastructures, both in Greenfield and Brownfield installations, can decrease the deployment costs for fiber infrastructure up to 21%.
