1. A wireless remote access base station for converting a downstream optical signal to a downstream radio frequency (RF) signal and transmitting the converted downstream RF signal wirelessly, and converting a received upstream RF signal to an upstream optical signal and transmitting the upstream optical signal, comprising:

  • an electro-absorption modulator (EAM) for converting the downstream optical signal to the downstream RF signal and the upstream RF signal to the upstream optical signal;

    an antenna for transmitting the downstream RF signal .wirelessly and outputting the upstream RF signal received wirelessly to the EAM; and

    an amplifier, disposed between the EAM and the antenna, amplifies the downstream RF signal and outputs the amplified downstream RF signal to the antenna.
