RELAY SYSTEM FOR MOBILE COMMUNICATION

摘要

PURPOSE: A serial-type optical high frequency repeater for use in mobile communication is provided to reduce a rental fee of an optical core leased line, a rental fee of a base station, and an install fee by using a serial-type. CONSTITUTION: A transmitted optical signal is laterally coupled on 1,2....n number optical directional coupler(forward). The transmitted optical signal is converted in a high frequency on an optical high frequency converter. A channel to service on a band-pass filter is passes. A high frequency high power amplifier amplifies the transmitted optical signal to pass it to a transmitting/receiving separation diplexer. The amplified optical signal is copied on a transmitting/receiving combination antenna. The amplified signal passes a band-pass filter and is converted by a high frequency optical converter to be coupled on an optical directional coupler(backward) .
