How cable operators update your network to FTTH  
 

Introduction:

As triple play(data+VoIP+TV) service is becoming popular, more and more cable operators upgrade their coaxial cable network to EPON/GPON+EoC HFC network or triple play FTTH network to attract users and satisfy their diversified needs.

What is the CATV HFC/FTTH network structure for cable television companies?
In old building upgrading projects, in order to avoid destroying the building structure and make full use of the current coaxial cable network and save cost, cable operators adopt EPON/GPON+EoC HFC network. Cable TV signal from optical transmitter and data, VoIP signal from EPON/GPON OLT are combined in EDFA(Erbium Doped Fiber Amplifier), divided by PLC splitters, transmitted on single fiber and reach to EoC master and EoC slave. Then EoC slave terminal demodulate the Ethernet service and CATV service.

In new cable TV and cable Ethernet projects, cable Ethernet service provider can consider about CATV FTTH network.
Cable TV signal from optical transmitter and data, VoIP signal from EPON/GPON OLT are combined in EDFA, divided by PLC splitter, then transmitted to home where located EPON/GPON ONU. Then ONU terminal demodulate the Ethernet service and CATV service.

Scenario 1: Pure CATV service application
For some subscribers, such as old generations, pure CATV service is enough, then it’s better to use FTTH CATV optical receiver terminal.FTTH WDM OPTICAL RECEIVER

Scenario 2: CATV and Ethernet service application
For some subscribers, there is only CATV service at first, but they will add internet service. Then we can update the FTTH CATV optical receiver to WDM FTTH CATV optical receiver, which have fiber optical output for connecting to ONU.

Scenario 3: HFC CATV and Ethernet service application
In upgrade projects, in order to avoid destroying the building structure, EPON/GPON + EoC solution is preferrable solution.

Scenario 4: Ethernet+VoIP+CATV triple play FTTH application
In new projects, in order to attract more subscribers and satisfy their Ethernet+VoIP+CATV triple play service demand, fiber to the home network is the most suitable solution for cable operators.
