Hybrid Fiber Optic Cable with Copper Wires

The return-path or upstream signals carry information from the home to the headend/hub office, such as control signals to order a movie or Internet data to send an email. The forward-path and the return-path are actually carried over the same coaxial cable in both directions between the optical node and the home.

The return-path or upstream signals carry information from the home to the headend/hub office, such as control signals to order a movie or Internet data to send an email. The forward-path and the return-path are actually carried over the same coaxial cable in both directions between the optical node and the home.

To prevent interference of signals, the frequency band is divided into two sections. In countries that have traditionally used NTSC System M, the sections are 52–1000 MHz for forward-path signals, and 5–42 MHz for return-path signals. Other countries use different band sizes, but are similar in that there is much more bandwidth for downstream communication instead of upstream communication.

Traditionally, since video content was sent only to the home, the HFC network was structured to be asymmetrical: one direction has much more data-carrying capacity than the other direction. The return path was originally only used for some control signals to order movies, etc., which required very little bandwidth. As additional services have been added to the HFC network, such as Internet access and telephony, the return path is being utilised more.

 

Multiple-system operators

Multi-system operators (MSOs) developed methods of sending the various services over RF signals on the fiber optic and coaxial copper cables. The original method to transport video over the HFC network and, still the most widely used method, is by modulation of standard analog TV channels which is similar to the method used for transmission of over-the-air broadcast.
