FTTH-Alternative Architectures and Construction Methods

FTTH construction is a large capital expenditure.  Centralized split architectures with home run fiber or Fiber Distribution Hubs are great designs and offer many benefits; however, there are alternatives to consider.  Distributed split architectures can offer many solutions when addressing rurally distributed customers or even more densely populated areas where competition is fierce.  Both public and private service providers owe it to their stake holders to provide the best possible service at the lowest possible up front cost. Utilizing staged splitting can reduce fiber and connectivity costs drastically while still delivering industry leading speeds.  Another potential cost savings can be found in utilizing existing duct structures or even microtrenching to defray construction costs.  Whether duct is empty or occupied, network operators can find savings in utilizing space by installing micro duct.  Both microtrenching and over-rides can help reduce the very expensive cost of directional boring in a brown field environment.
