    1. Introduction The EOC-20 is Multiplexer Unit for EoCNA (Ethernet over Coax Network Alliance) solution that efficiently extends 10/100 Ethernet circuits to over 900 meters(2,952feet) at 112Mbps using existing coaxial cable. The EOC-20 will allow Ethernet connectivity in existing facilities without pulling extra cable.

  • Page 23: Catv Transmission Amplifiers

    10.2. CATV Transmission Amplifiers Amplifiers often do not include EoCNA in their downstream band. In cases where this type of device is installed, it should be replaced with one that has a bypass in the EoCNA band. Bypass is done by connecting a low pass filter (LPF) with a cutoff frequency of 45MHz in parallel with the amplifier as shown in Figure 1 (a).

    10.3. Connecting an EoCNA device to the Coax network 10.3.1 Cable video signal If there is a cable video CATV signal in the network, both the TV and EoCNA devices should be connected to the TV connector of the wall outlet. In this case a simple installation should be used as shown in Figure 2.

  • Page 25: Isolator

    10.4.2 Isolator An Isolator is required at the entrance point to the apartment (the root of the coax distribution tree). The Isolator serves 2 purposes: To block the EoCNA signal from spreading outside the apartment to avoid security and privacy issues.

  • Page 26: Topologies

    10.5.2. Topologies The topology is assumed to be MxU access over a coax distribution topology in a building (see Figure 3). The MxU access refers to the coaxial distribution cables originating from the MxU wiring cabinet which may be located in the basement and spreading up the riser through the floors of the building to the apartments.
