Abstract

We propose abidirectional hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) for 128 optical network units (ONU’s) and investigate for different data rates i.e. 1.25, 2.5, 5 and 10 Gbps. To realize bidirectional transmission in single fiber, a circulator is used to isolate the uplink signals from downlink signals. The effect of crosstalk between uplink and downlink signals is alleviated by using different wavelengths i.e. 1300 nm and 1550 nm wavelengths respectively. It is found that the downlink and uplink signals can be transmitted with acceptable BER upto 118 and 107 km reach without any inline amplification respectively..
