The Optimization of Radio over Fiber Link by Proper Link Gain Control

we demonstrate the adjustability of optimal input power（OIP） of the radio over fiber（RoF） link by proper link gain control in the central unit（CU） and remote antenna unit（RAU）.The experiment results show that the reading and writing distance（RWD）of the radio frequency identification（RFID）service and...

Description
Summary:we demonstrate the adjustability of optimal input power（OIP） of the radio over fiber（RoF） link by proper link gain control in the central unit（CU） and remote antenna unit（RAU）.The experiment results show that the reading and writing distance（RWD）of the radio frequency identification（RFID）service and the throughput of the WiFi service have a max increase of 3cm and 6.975Mbit/s respectively when the OIP value equals to output power of commercial products,compared with OIP value with 5-dBm right/left shift to the output power.
