CityNet constructs dark-fiber networks utilizing an existing infrastructure - the sewer system. Using state-of-the-art Sewer Access Modules or SAM^SMs, man-accessible sewer technologies along with a small team of engineers, CityNet installs these networks at night while the rest of the world is asleep. This process allows for minimal disruption to both the environment and the city's residents. And, our process is approximately 60% faster than traditional rip-and-tear methods - up to 500+ feet in one night. Considering that the sewers are some of the deepest of municipal infrastructures (6 to 60 feet deep), CityNet's in-sewer fiber network is an ideal fit for agencies that require an extremely secure communications line. Additionally, a CityNet connection will provide a diverse route on which information can be rerouted in the event of a cut or a break to your current telecom carrier's network.
