Abstract

The invention belongs to the field of broadcast television, relates to a coaxial-cable Ethernet over coax (EOC) design, and in particular relates to a coaxial-cable EOC system with an upgrade function and a control method thereof. The coaxial-cable EOC system comprises an optical network unit (ONU), an optical receiver, an EOC headend device, an EOC terminal device and a spliter. The EOC terminal device is in no need of dismantling and reallocating, the numbers of the EOC headend devices and switchboards are not increased, or the EOC headend device and the EOC terminal device are not replaced, thus the bandwidth is increased in accordance with requirements so as to support a user to open more services. The optimal coaxial-cable EOC design provided by the invention is provided with the grading capacity-expending capacity and is easy to upgrade.

Description

technical field [0001] The invention belongs to the field of radio and television, and relates to a coaxial cable EOC design, in particular to a coaxial cable EOC system with an upgrade function and a control method thereof. Background technique [0002] EOC (Ethernet over Coax) technology is a technology that transmits Ethernet baseband data through a coaxial cable. The existing EOC access method is to place an active EOC head-end device in the corridor, one end of which is connected to the optical terminal ONU, and the other end is connected to the room through a coaxial cable, and an active EOC terminal device is placed indoors , demodulate the Ethernet data and send it to the computer or set-top box. With the continuous development of the integration of the three networks, the optical fiber is getting closer to the user, and the coaxial cable is only the last 100 meters left. However, the cable TV network in my country is mainly one-way and cannot carry multimedia inter...
