Abstract
Reflective semiconductor optical amplifier (RSOA) based wavelength division multiplexed radio-over-fiber passive optical network (WDMâRoFâPON) has been proposed and demonstrated, to transmit 2.5Â Gbps baseband (BB) and 1.25Â Gbps wireless data in downstream and 1Â Gbps BB data signal in upstream over 25-km single-mode fiber (SMF), and wireless downstream signal over 25-km SMF as well as 5.2Â m free space in air. In the downstream, 2.5Â Gbps BB data and 1.25Â Gbps wireless data are modulated using single-electrode Mach-Zehnder modulator (SD-MZM) based on double-sideband with optical carrier suppression (DSBCS) scheme and simultaneously transmitted by incoherent light injection technique and employing fiber Bragg grating (FBG) at the base station. RSOA is utilized at the user end to reuse the carrier for uplink transmission. High receiver sensitivity, low bit-error-rate (BER) and excellent eye-diagram, eye height are achieved in our proposed network system and the results affirm the acceptability of proposed RSOA based WDMâRoFâPON.
