Today, cable television is a single network system that takes a drastic step, expanding from its long established role as an entertainment services industry, which includes video television and broadcast on demand to a service industry. high speed data.
The original project of cable television systems was a one-way analog transmission system using coaxial cable. Today, cable companies have found that fiber is the perfect choice for transmitting signals to various customer locations.
In this distribution system, each location is connected to a terminal isolated by a dedicated optical fiber, and the tuner connected to each TV client is parked at the remote terminal. Channel selection signals are sent by fiber from the customer location to the remote terminal. The only channel selected is the only channel transmitted by fiber from the remote terminal to the associated TV.
This app helps prevent outages for large numbers of customers over a period, which gives cable companies a better customer relationship. It also helps increase the company’s revenue, giving them a return path that they can use for telephone and Internet connections.
Due to the increased demand for communication signal transmission, cable television is in the middle of advancing its existing systems with fiber optic technology.
Benefits for cable end-users
With fiber optic technology, cable companies can provide customers with a much better quality image while reducing operating costs, because fiber optics cost less to maintain.
One of the primary uses of fiber optics for cable companies is its large information carrying capacity, which is hundreds of times larger than copper wire. Optical fibers also provide essential protection against electrical interference and lightning.
Fiber optics are extremely reliable because they do not corrode moisture, shorten water and behave at high speeds in any type of difficult climate. Optical cables are very light due to their small size and length, making installation easy. In the case of fiber optic cables, there is no danger of fire as it does not transfer electricity.
Without losing power, fiber optic cables can transmit television signals over a long distance thanks to the technology of using thin glass wires. In different areas of the network, single and semi-modal signals will be used. The signals will be sent from the head office to the optical nodes using single mode fibers and then converted to multimode.
Optical cables use light signals as a substitute of electricity, which makes signals much clearer and offers very low signal losses over a wide frequency range, without interference with other signals.
In the coming years, most cable television companies will have fiber optic installation, which will be an advanced and versatile communications network solution.
