|Title in Arabic||Performance Improvement of Wavelength Division Multiplexing Passive Optical Networks (WDM PONs)|
Passive Optical Network (PON) introduces a good data transmission rate and large bandwidth. We have demonstrated a bidirectional PON system based on a Fabry-Perot laser diode (FPLD) with two cascaded array waveguide gratings (AWGs). The downstream data rate equals to 10 Gbps and the upstream data rate equals to 2.5 Gbps. This network is classified to 10GPON Standard. FP-LD is used at optical network unit (ONU) as transmitter so it can re-modulate the downstream signal with upstream data, and then re-sent upstream towards the central office (CO). FP-LD is considered as low cost optical source, it is less costly than other sources like distributed feedback (DFB) laser, vertical cavity surface emitting lasers (VCSELs) and reflective semiconductor optical amplifier (RSOA). The main idea for using AWGs in the system is to increase the capacity, security and privacy. AWGs are used to multiplex and demultiplex different wavelengths in wavelength division multiplexing PON (WDMPON). Our proposed systems is effective low cost system and the injection locked FP-LD is used as low cost colourless transmitters for high speed optical access exploiting WDM technology.
