    What is the PON+EOC Network Solution?

  • Learning Center    release time:2019-09-09
  • PON+EOC is a way to effectively combine PON network and EOC access mode. PON network is the input end of EOC data interface. PON optical fiber transmission medium as a pre-stage in order to enrich the coaxial cable network access resources as a subsequent stage transmission medium, can solve the conventional coaxial cable objective to limit the bandwidth limited noise in the aggregation access CMTS . In addition, the bandwidth of the EPON communication system exceeds 1 Gbps, the downstream bandwidth of the GPON system is as high as 2.5 Gbps, the transmission distance reaches 20 km, and the bandwidth of the EOC per service area is 300 Mbps. The PON+EOC system offers significant advantages in service provisioning capabilities and deployment flexibility.

    The PON+EOC solution is a function that realizes the two-way transformation of cable TV without adding wiring, changing the original coaxial cable and equipment, and without the need for two-way transformation of the cable TV. It can not affect the cable TV signal transmission and At the same time, high-speed Internet access through coaxial cable is an advanced broadband access and two-way transformation solution.

    The PON+EOC broadband access system has the following significant advantages:

    Transmission Distance

    The PON access segment can cover the transmission range of 20Km, and can easily cover the coverage from the front-end equipment room to the access node; the EOC access segment, because the system uses the low frequency transmission of 7.5MHz to 65MHz, does not signal the existing TV channel. It will have an impact, and because of the better anti-attenuation performance of the low-frequency signal and the relatively high-frequency signal, it can adapt to the coaxial distribution network in the cell, and can achieve the ideal transmission bandwidth on the 40dB link.

    Anti-interference capability

    The PON access segment adopts optical fiber transmission technology and is not interfered by electrical signals; the EOC access segment avoids high-interference low-band regions between 0 and 7 MHz, and also adopts advanced OFDM (Orthogonal Frequency Division Multiplexing). Modulation technology and Turbo FEC error checking greatly improve the anti-interference ability.

    High bandwidth and multi-user access capability

    EPON access supports bidirectional 1.25Gbps bandwidth, and GPON supports 2.5Gbps downstream and 1.25Gbps upstream. In the EOC access segment, the head-end device supports 600 Mbps physical layer bandwidth and 300 Mbps MAC layer bandwidth, and the TDMA time division multiple access technology used in uplink and downlink can meet the needs of high-density users and high-bandwidth services.

    Both PON and EoC devices support remote management control.

    Conclusion,Solution of PON + EOC can implement the transmission of CATV, voice, computer data in two-way HFC network at the last few hundred meters. By combining the technology of EPON, GPON and EOC with technology of HFC, it will greatly promote the development of application of two-way access of HFC digitization and three-in-one network. The core of this solution is that based on the existing resources of HFC (Hybrid Fiber-Coax) network that has been built, to construct manageable and maintainable HFC multimedia broadband access network in telecommunication level, and by sufficiently combining unique advantages of telecom industry and HFC accessing of broadcast television, to develop service of broadband internet, VOIP, video-on-demand of IPTV and so on. Sopto provides various EOC products assembled with HFC optical receiver module, ONU module, fiber optical transceiver and EOC head-end module corresponding to different user scenario, which is the best choice for EOC access network construction with low investment for operators.With modularized product design, there are various product modalities by combining different function modules.
