Just How Do Cable Tv and Fiber Optics Work?

Fiber Optic cable and the old popular (coaxial or RF) cable are two different cable program systems which can be used to spread different services to finish users--homes. Generally speaking, they differ only in technological (electrical/communication) viewpoint. This is mostly necessary for the network providers since end users or people do not care about the technology, they are involved in services and TV channels.There are few different ways which can be used to deliver common services like television programs via cable systems. Each has some disadvantages and advantages and needs various topology or community infrastructure.Analog TelevisionThe first this networks were simply an extension of the broadcasts in the air. It was executed by deploying regular aerial cable (but with lower losses) from the cable system headend to the houses. Due to the distances there have been also many amplifiers at particular points to make sure expected signal levels. The communication was completely one-way, but later most such cable networks were extended allowing bidirectional communication required for use of the net by using techniques like DocSys.This strategy can be utilized with RF (coaxial) and fiber cords. Fiber optic cables will also be utilized in some cases to spread the old analog cable television. The bonus of optical network is because it can use available fibers in current fiber optic cables and the cable losses have become low.Digital TelevisionDigital television in cable systems can be split into two totally different means of circulation. The first one is an equivalent to digital broadcasting and another way mainly utilized in fiber optic systems is IP television.Digital Cable BroadcastingThis is equivalent to analog distribution over (RF) cable but with digital transmission. The exact same technology (modulation) may be used for terrestrial broadcasting but frequently, there are more effective systems that take into account specific qualities of cable systems. One typical case is DVB-T program which will be used in Europe for digital terrestrial movie transmission but cords use similar DVB-C system.IP TelevisionThis is the hottest digital television distribution used with fibre optic cable systems. It indicates circulating TV programs with the Internet Protocol Address process that is the spine of web communications. Each TELEVISION routes is protected with either MPEG-2 or MPEG-4 system and then dispersed over fibre optical cable system to the domiciles. The advantages are enormous. The capacity for the number of channels is pretty high, all the channels may be secured and spread with very high quality, it is very an easy task to distribute HD channels, access to the internet is very simple because of the IP protocol and indigenous technology.
