Abstract :
The coexistence of Gigabit-baseband and wireless long term evolution, worldwide interoperability for microwave access and 13 ultrawide band sub-bands OFDM-based signals in hybrid metro-access networks is studied numerically. Three options to share the optical power among all the signals are analysed. A coexistence of all those signals, with error vector magnitude not exceeding -17 dB, is shown for reaches up to 100 km of standard single mode fibre using optical dispersion compensation.
