Abstract

The invention discloses an Ethernet passive optical network (EPON) optical network unit fusing an Ethernet over coaxial cable (EoC) function. The optical network unit comprises an EPON remote terminal, an EoC head end and an inter-board connector, wherein the EPON remote terminal is connected with the EoC head end through the inter-board connector, and finishes equipment configuration management and the PON access of Internet protocol (IP) data; the inter-board connector transmits megabit Ethernet data, a resetting signal and a port connection status indicator signal; and the EoC head end finishes conversion between the Ethernet data and low-frequency EoC data and the coupling of high-frequency/low-frequency EoC data. By the optical network unit, the accessing of an EoC signal can be realized on the basis of no influence of original coaxial network performance and no change of a coaxial network topology structure, the volumes and sorts of networking equipment can be decreased, a mounting procedure can be simplified, power consumption can be reduced, unified management can be realized, operation and maintenance cost can be decreased, networking flexibility and high network adaptability can be achieved, the capability of communication with terminal equipment and anti-jamming capability are high, and transmission frequency points can be flexibly selected.

Description

technical field [0001] The present invention relates to the application of EoC (Ethernet over Coaxial cable, Ethernet technology based on coaxial cable transmission) in the field of optical communication, in particular to a kind of EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) which integrates EoC function ONU (Optical Network Unit, optical network unit). Background technique [0002] The EoC coaxial Ethernet system is a series of products specially designed for radio and television cable network operators to realize bidirectional data transmission based on the existing coaxial cable distribution network. It is a HFC (Hybrid Fiber-Coaxial, optical cable-coaxial cable hybrid network) An economical and efficient solution for realizing two-way network reformation. The EoC system can work in the active and passive cable distribution network environment, and quickly realize digital TV return channel, high-speed Internet access, high-definition video o...
