Installing Fiber Optic Cables in Sewers Maximizing the Potential of Existing Underground Infrastructure

The increasing demand for high speed data communications and providing fiber optic network connectivity in inner city cores proved to be more challenging than previously though. Disruptive and expansive methods of digging up the streets and placing multiduct structure delayed many service providers in delivering their services to end users and created havoc in the cities. The sewer system has been designed and built as a network. Revolutionary idea to utilize that network, that is the most extensive open-access conduit network in any city, and place fiber optic cable attached to the top wall of the pipe started a new trend. This has become a preferred method of installations for cities that want to leverage their existing infrastructure, minimize disruptions and create additional revenue. Also, necessary maintenance, inspection and rehabilitation are done on behalf of telecoms further benefiting the owners of ROWs and sewer pipes. How it is done, technical challenges and solutions.
