Abstract
A wireless remote access base station for converting a downstream optical signal to a downstream radio frequency (RF) signal, transmitting the converted downstream RF signal wirelessly, converting a received upstream RF signal to an upstream optical signal, and transmitting the upstream optical signal is provided. The remote base station includes: an electro-absorption modulator (EAM) for converting a downstream optical signal to a downstream RF signal and an upstream RF signal to an 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, which is located between the EAM and the antenna, amplifies the downstream RF signal and outputs the amplified downstream RF signal to the antenna.
