Problems solved by technology

The main disadvantage of passive EOC is that the household distribution network in the building must adopt the star-shaped centralized distribution method, which is a point-to-point (P2P---Point to Point) topology structure, which is not suitable for most existing cable TV systems. Point to multipoint (P2MP—Point to Multiple Points) network topology

Abstract

The invention discloses an upload amplified coaxial Ethernet access terminal device which comprises an RJ-45 data port set, an Ethernet exchange chip, an Ethernet over coax media access control (EOCMAC) chip, and EOC physical layer chip, a network transformer, a combining filter, a data coaxial port F, a cable television coaxial port F and an upload amplifier. A high frequency output port of the combining filter is connected with the cable television coaxial port F. A low frequency output port of the combining filter is connected with the data coaxial port F. The combining filter is connected with the network transformer. A download data port of the network transformer is connected with the EOC physical layer chip. An upload data port of the network transformer is connected with the upload amplifier. The upload amplifier is connected with the EOC physical layer chip. The upload amplified coaxial Ethernet access terminal device is matched with a local side device so that an existing cable television coaxial network is fully used and point-to-multipoint broadband access with low cost and high property can be achieved.

Description

Technical field [0001] The invention involves a kind of uplink -enlarged coaxial Ethernet access terminal device, which is suitable for receiving cable TV signals and sending and receiving broadband data signals at the same time.The device is a technical field of coaxial broadband multi -business access network. Background technique [0002] With the rapid progress of informatization construction, people's demand for multimedia communication such as data, voice, and images is becoming increasingly strong. The high -speed Internet, high -definition / standard Qing radio and television, IPTV, VOD, VOIP and other businesses gradually become the main business of the access network.Therefore, the development trend of users accessing the network is broadband, two -way, and multi -business.At present, the home broadband access network mainly includes Telecom's twisted network network, China Unicom and other specialized data business companies, Ethereum network, and Copper network entry ne...
