Cable TV is a network system that is now making a radical step forward by extending from its long-established role as a segment which comprises on-demand as well as broadcast TV to a high-speed internet service. The actual design of US cable TV systems was the analog transmission system with coax cable. Now, cable TV providers have found fiber is the ideal means for transmitting signals to many subscriber locations.
In this distribution system, every customer location is connected to a separate terminal by a devoted optical fiber as well as the tuner connected with every individual subscriber television set is stationed in the terminal. Cable selection signals are being sent over fiber from customer’s location to it. The single chosen channel is the only one transmitted over fiber from it to the associated television set.
This application helps avoid an outage for a big number of subscribers during a time period, and it in turn provides cable TV providers with a better subscriber relationship. It also helps increasing the revenue of companies by providing them with a return path wherein they can use for phone connections as well as the internet.
Owing to the growth in demand for communications signal transmission, the cable TV industry is in the midst of developing their existing systems using fiber optic technology.
With the technology, cable service providers can offer their subscribers a better quality picture on TV while at the same time decrease their operating costs since fiber optics cost less to maintain.
One of the main uses of fiber optics to cable businesses is the large chunk of information carrying capacity. This is hundreds of times more than copper wire. Besides, fiber optics offers necessary protection from instances of electrical interference as well as lighting.
Fiber optics are greatly reliable since they do not short out in water or corrode in moisture, and still perform in any kind of harsh water at high speeds. Optic cables are extremely lightweight owing to their small sizes, and long lengths make them more easy to install. With these cables, there is no risk of fire hazards since they do no transfer electricity.
Without losing the power, these cables can carry TV signals for an extremely long distance owing to the use of extremely thin glass strands technology. In different network areas, both single and multiple mode signals will be employed. They will be sent from central office to fiber optical nodes with single mode fiber as well as converted to multiple mode fiber.
Optical cables use the light signals instead of power and this makes them clearer and provides an extremely low signal loss over an array of range frequency without interference to other signals.
Inside the subsequent few years, most cable TV companies will have set up fiber optics, which make it a versatile and advanced communications network solution.
