Embodiment Construction
[0037] A cable TV network broadband access system based on OFDM technology is to realize broadband access, video on demand (VOD) and other functions on the existing cable TV network by using OFDM technology.
[0038] Referring to the system shown in Figure 2, the system mainly includes:
[0039]Coaxial cable switch based on OFDM technology: The standard Ethernet data signal sent by the IP data network is modulated to the idle frequency band of the CATV network using the OFDM modulation method, so that the data signal and the TV signal can be transmitted on the same cable without mutual interaction interference.
[0040] Data mixer: By using this device, the data signal and the TV signal can be mixed together and sent to the CATV distribution network through a coaxial cable.
[0041] Data jumper: Based on the fact that most CATV networks use one-way TV signal amplifiers, which cannot provide two-way channels for data signals, this device can solve the above problems. Provide ...
