2-Way HFC
home:TELECAST TECHNOLOGY >> Solution >>2WAY HFC
Typical System Configuration Diagram
System Features:
1. It can be used to transmit analog and digital TV programs, as well as provide customer with internet access and develop VOD.
2. How many customers have access to the system? And how many customers will use internet in the future?
3. Because the system has more frequency resources, operator can add more downstream data transmission channels at the head-end. Thus, the subscriber will get faster speed.
4. Make full use of the original transmission network, there is no need to rebuild transmission platform for transmitting data service, saving a lot of investment
5. The cost of the subscriber for receiving data is less than USD40. They just need a CABLE MODEM for internet access.
