High capacity radio-over-fiber systems for multicarrier signals with dynamic routing

“…It is seen that all the constellation points are very well separated and we have only 3% EVM values after total 950 m MMF and mid-span routing. [3] CONCLUSION In this paper, we have demonstrated the transmission of multi-carrier 64-QAM signal at 18.3 GHz over 4.4 km MMF employing the SCM method. The performance of the SCM multi-carrier RoF system is transparent to the number of carriers and signal format.…”

Optical in-building network techniques

“…120 Mbit/s on a single subcarrier in QAM-64 format has been transported over 4.4km 50µm core silica graded-index MMF, at a carrier frequency of 17.2GHz. Multi-tone techniques as used in wireless standards can also be handled; a 52-carriers OFDM 16-QAM 36Mbit/s signal at 18.3GHz has been conveyed over 950 meters of silica 50µm core silica gradedindex MMF, including intermediate wavelength conversion by cross-gain modulation in a single SOA [5] ; see Fig. 2.…”

Radio-over-fiber techniques for advanced in-building networks

“…As illustrated in Fig. 3, in a point-to-multipoint network architecture optical routing nodes (RN-s) may be deployed to direct the RoF signals to the appropriate RAP-s. [7]. A static wavelength router after the SOA determines the routing path.…”
