Fiber Optic Technology in Everyday Life

Cable television is one network system today that is making a drastic step forward by spreading out from its long-established role as an entertainment service industry which includes on-demand video and broadcast television to a high-speed data service industry.

The original design of cable television systems was the one-way, analog transmission system using coaxial cable. Today, cable television companies have found that fiber is the perfect choice for transmitting signals to multiple customer locations.

In this distribution system, each location is connected to an isolated terminal by a dedicated optical fiber and the tuner connected with each individual customer TV set is stationed in the remote terminal.

Channel-selection signals are sent over the fiber from the customer location to the remote terminal. The single selected channel is the only channel transmitted over the fiber from the remote terminal to the associated TV set.
