In order to satisfy the demands for different high bandwidth services

a hybrid access network for simultaneous transmission of wired and wireless signals is presented.In the downstream links

wireless signals are transmitted in the phase modulation format

wired signals re-modulated in the intensity modulation format on optical carriers

and different demodulation schemes employed for modulation and reception at the ONU.In the upstream links

wired base-band signals are remodulated by using the carrier reuse technology and transmitted to the OLT

thus simplifying the system device configuration.The system reliability and effectiveness are verified by using the optical software Optisystem 7.0.The simulation results show that fairly good eye diagrams can be obtained at the user end after the wireless link signals and wired BB signals are modulated and transmitted

indicating that they can be accurately received and the upstream BB signals can also be accurately received at the OLT by using the carrier reuse technology.
