The term “broadband” can be used in a variety of ways and most often represents a communication line or medium that has greater bandwidth than a typical data or phone line. Coaxial cable used with a television is an example of a copper broadband medium. Lewis County PUD uses fiber as a broadband medium to transport information from one point to another in the form of light (fiber optics). Fiber is the fastest, most reliable broadband medium available. Did you know that the entire contents of the Library of Congress can be transmitted over one fiber across the country in 4 seconds?
Light is easily transmitted through fibers or thin rods of glass. The use of fiber in telecommunications is growing because it is durable, reliable, and provides more bandwidth (information-carrying capacity) than traditional metallic-based cable. The use of fiber optics in telecommunications ranges from global networks to local telephone exchanges to internet subscribers’ homes. All involve the transmission of voice, data, or video over distances from less than a mile to hundreds of miles.
