Application of optical millimetre-wave generation to the provision of fibre/radio access networks will require that broadband data can be imposed on an optical millimetre-wave carrier. The authors analyse the direct data modulation of a two-tone optical carrier and show high tolerance to fibre dispersion combined with low complexity.
