Description and expertise of the organisation:
Expertise in Optical Access Network architectures and sub-systems, radio-over-fibre systems at microwave and millimetre wave frequencies.

Worked with BT on the first Long reach optical access network demonstration. Published the first all-optical wavelength converting PON demonstration. Demonstrations and modelling of radio-over-fibre networks at microwave and millimetre wave frequencies.

Extensive and state-of-the-art optical and electrical experimental facilities including network layer emulation. EPON test-bed, 4 channel 10Gbit/s burst mode test bed. Radio over fibre test-bed form WiFi, Cellular (GSM, CDMA, LTE), WiMAX and 60GHz. Modelling of optical access networks at physical and network layer.

Research interests / Project ideas
OFDM and OFDMA PON. Long reach, Wavelength Converting and wavelength switched PON. Radio over fibre overlays.
