Equipment required in a CATV FTTH network

  In some existing CATV operator network or some telecom upgrading projects (eg. in old buildings), to avoid destroying the building structure and make full use of the current coaxial cable network, cable operators usually adopt a FTTH PON+CATV network solution.

CATV FTTH Triple Play solution scenarios

What is called “FTTH PON+CATV” network?

  One hand, Cable TV signal from optical transmitter. Other hand, data and VoIP signal from FTTH GEPON/GPON OLT uplink side. The two ways signals are combined in EDFA (Erbium Doped Fiber Amplifier), divided by PLC splitters, transmitted on single fiber and reach to the end user family. In some case the combination signals will reach to the CATV and Ethernet network system: EoC master and EoC slave (Optional). Then EoC slave terminal demodulate the Ethernet service and CATV service.

  • CATV and Ethernet over cable service application
  • HFC CATV and Ethernet service Scenario
  • Data+VoIP+CATV triple play scenario

Features

  • High quality: original system optimization control technology and RF pre-distortion technology ensure that the system can acquire the maximum CTB, CSO in the case of excellent CNR performance.
  • Flexibility: it can transmit 1~2 ways of SAT-IF signal separately or adding 1 ways CATV signal
  • Reliability: 19 “1U standard rack, built-in high-performance dual switching power supply, etc.

WDM EDFA

  An Erbium-Doped Fiber Amplifier (EDFA) is a device that amplifies an optical fiber signal (from CATV).  An WDM EDFA is used to integrated 1550nm CATV (optical signal) and 1490nm /1310nm data stream from the PON into single fiber transmission.
