Abstract

The propose design is for a cost effective Full Duplex Wavelength Division Multiplexed Passive Optical Network. This system can transfer data up to 2. 5 Gbps to up to 10 Gbps over a 20km of a single feeder fiber using single light source per Optical Network Unit. Here, a Non-return to zero (NRZ) downstream signal is first frequency up-converted to around 20 GHz before being fed to Mach-Zehnder Modulator for downstream transmission. CW DFB Laser Array is used as a carrier for optical signal. After transmission over feeder fiber, a portion of this signal is detected at the Optical Network Unit and one of its signal is up streamed with the help of Optical Transmitter at a frequency of 1550nm. For amplification EDFA is used. To overcome the bandwidth limitation, we apply a Buffer Selector at upstream receiver. At receiver side Photo detector PIN is used to detect the optical signal.
