DWDM-interleaved photonic architecture for wired and wireless services

A spectrally efficient optical distribution system based on frequency interleaving is investigated. The technique shows effective interleaving of three channels of baseband signals for wired applications with a data rate of 2.5 Gbps and three channels of 62.5 GHz radio-over-fiber for wireless services with a data rate of 1.25 Gbps, with complete spectrum occupying a bandwidth of 110 GHz. The interleaved signal thus contains six users is transmitted over 60 km standard SMF without any dispersion compensation. The performance of this hybrid system is evaluated on the basis of BER, OSNR, Q-factor and receiver sensitivity.
