What is HFC?

The Internet is many things these days, but no matter how many new features are invented for Internet capabilities, it is still necessary for cables to connect these internet -related machines and to transfer these signals. Like the revolution on the computer, it has used the design and functionality of computer cables in recent years has jumped forward. What was used to transmit only a small amount of data is now entrusted with the transfer of broadband data flows. This is where HFC comes. Of course, the data transmitted via HFC cables are traditional letters and numbers; However, it also includes newer technological data such as streaming audio and video and internet phone calls. What used to be only cable TV signals transmitted via coaxial cables have now become broadband signals sent via HFC cables. It is also e -mail and file transmissions, and with HFC broadband capacity, transmissions can be as large as needed. Unlike the individual toOaxial cables or individual cables from optical fibers that are designed to suit only downstream operations, HFC cables are manufactured for two -way operation, as the full Internet connection service requires the provider to verify customer records. In this way, HFC cables are the next generation of data transfer cables.

HFC usually occurs in the form of a network, such as a cable TV company that uses optical fiber cables at its end to transfer data to customers who have coaxial cables at the end. This is known as the "trunk and branch" system, with a cable company like a suitcase and customers as branches. Nowadays and age of conglomeration, many cable TV companies offer much more than traditional television. They transmit video, sound and internet services; Therefore, they use HFC cables. Such networks also usually use cable modems thatThey are created according to DocSis standards.
