EoC system Introduction

   H1, OUT1, H2 and OUT2 shall used as a group.

         OUT1: subscribers

         H1: former amplifier output port

         H:former amplifier input port

IN: up-grade combined signal input port.

    Add EoC Bridge to realize the modification of one-way amplifier. Marks on the bridge:

2.1.1One-way amplifier:

2.1 Amplifier:

1.Circuit part:

       The max output data signal level of the SUB-HEADEND module is 120dB (Default), and could adjust via inner management interface.

   d If we need one EM90 provide data to two input and output ports simultaneously, we should use splitter at first and then insert the interpolator.

   c EM90 module output cable connects with the corresponding interpolator port;

   b Corresponding EoC SUB-HEADEND output port connects with the subscriber. Output signal is the combined signal of TV signal and data signal;

  a Original cable TV signal input cable connects with input port on the side of EoC Sub-headend;

EM90 is the data module in EoC SUB-HEADEND. There are two EM90 in one standard EoC. Maximum configuration is four.
