Fast tunable lasers in radio-over-fiber access networks [PDF]
, 2006 The authors present a novel concept of employing optical wavelength packet switching (WPS) in radio-over-fiber (RoF) access networks. The Central Station is equipped with a fast tunable laser (TL), which is externally modulated with a data signal ...
