Abstract :
We propose a full-duplex millimeter-wave fiber-radio network for providing wireless customer access to broadband services. It consists of a hybrid star-tree architecture connecting remote antenna base stations to a central control office (CO) by incorporating wavelength-division multiplexing (WDM) of the optical signals and subcarrier multiplexing (SCM) of the radio signals. These multiplexing schemes allow the sharing of equipment at the CO and therefore enable a simple radio distribution architecture to be implemented. We also demonstrate a 35.5-39.5-GHz full-duplex fiber-radio star-tree network, featuring three WDM carriers in the downstream and a single carrier in the upstream. Each downstream wavelength carries three 155-Mb/s BPSK SCM channels between 35.8-39.3 GHz, while a 37-GHz carrier transports 51.8 Mb/s upstream.
