Implementation of fiber optic cables in sewage system

Implementation of optical fibers in the cities causes the involving excavations of city streets. These excavations cause pollution, traffic hold-ups, economic loss, and unsafe conditions to the inhabitants in every city. Even worse, the repair of the streets after excavation rarely left the streets in acceptable condition. These forced mayors to issue moratoriums on new open cut excavations involved in the "Last-Mile" work. The "Last-Mile" is the section of a network that connects from the basement of an end-user building to the city-area network that surrounds a city. The novel idea of leasing space inside of existing sewers by telecommunications companies has a rather interesting appeal in that owners of existing sewers get to generate a new revenue stream and telecommunication companies could install their optical fiber cables at an attractive cost. This paper describe the advantages of building optical fiber networks inside existing sewers, base conditions for this implementation and briefly describe the interactions between the pipe, cable and liquid. The computer simulations was execute with MOUSE model in the Slovakia.
