Reconfigurable Radio Access Unit for DWDM to W-Band Wireless Conversion

摘要

In this letter a reconfigurable Remote Access Unit (RAU) is proposed and demonstrated, interfacing dense wavelength division multiplexed (DWDM) optical and W-band wirelesslinks. The RAU is composed of a tunable local oscillator, a narrow optical filter and a control unit, making it reconfigurable via software. The RAU allows selection of a DWDM channel and tuning of the radio carrier frequency. Real-time transmission results at 2.5 Gbit/s and performance measurements with offline data processing at 4 and 5 Gbit/s are presented. Error free real-time transmission was achieved after 15km of standard single mode fiber and 50m of wireless transmission with carriers between 75 and 95 GHz.
