Optical Routing and Multicasting of Multiservice RF over Fiber Signals

In this paper, we describe multiple input/output, multiple-service operation in a fully functional switch. Here, a 3times3 crosspoint RoF switch architecture is constructed and characterized. Time-domain switching effects on the distortion of RF signals and the linearity of the switch are measured and analyzed. Routing of multiple wireless services such as multiple digital TV channels and WLAN signals is demonstrated
