A guide to choose EoC: Ethernet over Coax equipment

EoC Equipment Overview

 Ethernet over Coax or (EoC) is the technologies that supports the transmission of Ethernet or IP Video over coaxial cable.The application of EoC is famous for those features: simple, stable, secure and low cost etc.Generally speaking, EoC equipment has two models, including:

  • Passive Eoc(baseband);
  • Active EoC.
    FOT EoC master/Slave

    FOT EoC master/Slave

Technologies & application of Active EoC

 Due to the technology issue, as we know, currently the main EoC solution in the market we are using is active EoC. This post is also mainly focus on the active EoC, and introducing its main technologies & applications:

  • HomePNA
  • WiFi over Coax
  • MoCA-Multimedia over Coax Alliance
  • HomePlug (BPL/AV)
  • ECAN

Key EoC parameters to choose:
How to choose a suitable EoC product according to your project or requirement? We may find the answer on those five key factors as following:

  1. The main IEEE protocol features, for example, IEEE 802.1D, STP protocol to prevent the spanning tree loops, and broadcast storm suppression.
  2. Support rich OAM management: supports SNMP v1/v2/v3 all MIB, CLI command line, Web NMS, Telnet and remote upgrade, easy maintenance.
  3. Support time division multiple access (TDMA) protocol, to satisfy the distribution structure in existing HFC network, to meet the “point to multipoint” mode, to ensure multi-users’ high transmission traffic.
  4. Support bandwidth limitations both at uplink and downlink direction.
  5. EoC slave/terminal should support port isolation, to provide a user application security.

EoC Applications
With the matures development in EoC technology, EoC solution is becoming a major choice for cable, HFC broadband access network.EoC master works with EOC slave in Ethernet over coax network and provides layer-2 Ethernet Access to users through television coaxial cable and meanwhile without influence on the existing CATV signal transmission.
