Optimized synergy in FTTH infrastructure deployment: Pragmatic as well as structural approaches

Underground installation of utility infrastructures such as energy and telecoms is prevalent in large parts of Europe. As this labor-intensive trenching comprises 70% - 80% of deployment cost, the overall investment for Fiber-to-the-Home installations can be significant. Important reductions in these costs are possible by performing road works in synergy. With the increased level of detail in the geographical information bases containing all information on the installation per operator, opportunities for synergies are easier to spot and could lead to very important reductions in the operators´ costs. Policy measures recently also give a lot of focus in facilitating the rollout of high-speed broadband networks and cross-utility coordination. Several approaches can be considered to really capture potential savings and benefits in the deployment phase. This paper discusses pragmatic as well as structural approaches towards deployment cost optimization based on synergetic rollout schemes.
