Topological graph of radio and television one-way HFC network

The solution is mainly used for digital TV optical fiber and coaxial cable hybrid transmission, and the front end uses optical transmission to the optical workstation node. Then coaxial cable and power divider are used to connect to thousands of households. This solution is simple and flexible.

EPON+EOC ----Optical fiber to the building, coaxial cable to the home

The CATV front end uses optical fiber to connect to the optical workstation. The Internet uses the EPON optical network to bridge and switch, and the CATV signal is mixed at cable bridge switch to access users through coaxial cable.

EPON+EOC ----Optical fiber to the building, coaxial cable to the home

CATV and the Internet are connected to the cable bridge access point by sharing an optical fiber through the optical combiner, and then they are converted into electrical signal and delivered to the end users using coaxial cables and power dividers.

Docsis EOC for EPON ----Optical fiber to the building, coaxial cable to the home

The CATV is transmitted to the optical workstation through optical fiber, and the Internet is transmitted to the EPON terminal through PON network. Finally, the Internet signal and CATV signal are connected to the CMTS, and delivered to the user's DOCSIS CM terminal through the coaxial cable and power splitter, realizing the two-in-one transmission of network.
