Abstract

The present invention provides a cable TV broadband network system and networking method thereof. The system includes an OLT apparatus of an EPON, an ONU apparatus of the EPON, an LAN switch, a CLT apparatus of an EOC and a CNU apparatus. The OLT apparatus of the EPON is disposed at the front machine room; the ONU apparatus of the EPON and the LAN switch are disposed at an optical node; and the CLT apparatus of the EOC is disposed at a floor centralized distributing box. The CLT apparatus is connected to the CNU in the room of the user sequentially through a combiner, a distributor, and a coaxial-cable. A networking mode of EPON+LAN+EOC (1.215 GHz to 2.535GHz) is adapted to the optical transmission network from the optical node to the building. Bandwidth entering home can achieve more than 10 Mbps, the problem of complex wiring is solved, and the effect can be compared with FTTH, and the low construction cost is low.

Description

technical field [0001] The invention relates to a cable TV broadband network system and a networking method thereof, in particular to a broadband network system structure and a networking method suitable for broadcasting and television fields. Background technique [0002] The networking modes of the CATV broadband network in the prior art include: [0003] 1. EPON+EOC networking mode: the aggregation layer network uses EPON technology ONU (Optical Network Unit Optical Network Unit) to deploy at the optical node; EOC refers to a transmission technology of Ethernet signals on coaxial cables, where CLT ( Coax Line Terminal coaxial Ethernet head end) is arranged at the optical node and connected with ONU. The modulated radio frequency signal is connected to the CNU (Coax Network Unit coaxial Ethernet terminal) in the user's room through the coaxial cable distribution network to realize data connection. into the network. At present, it is mainly used by radio and television ne...
