Broadband convergence of 60-GHZ ROF and WDM-PON systems with a single modulator for bidirectional access networks

We experimentally demonstrated a converged 60-GHz ROF and 10-Gb/s WDM-PON system using an integrated modulator and a single wavelength for the first time. Orthogonal phase modulation is used to relieve the crosstalk while providing centralized bidirectional connections.
