Crosstalk suppression and user capacity enhancement in time and wavelength division multiplexed passive optical network incorporating different modulation formats

  Talwinder Singh,  Ramandeep Kaur

In this paper an innovative scheme has been presented to alleviate the effect of crosstalk in Time and Wavelength Division Multiplexed Passive Optical Network (TDM-WDM PON) by using different modulation formats. The main work is carried out to improve total system reach and enhance user capacity. A precise way has been suggested to increase number of users of system and exhibit the absolute least inter symbol interference on WDM-TDM data. Furthermore, some techniques has been recommended to employ these transmitters’ diversities with reasonable arrangement complexity. To support multiple user, hybrid modulation is proposed for TDM-WDM PON with the integration of Differential Phase Shift Key (DPSK) format for downstream and Non Return To Zero (NRZ) format for upstream. Thus system is competent to support 1024/64 users per wavelength. Data rate of system is 120 Gb/s for downstream as each wavelength carry 10 Gb/s and 80 Gb/s for upstream. This is found that projected technique is appropriate to and exhibit best results in terms of Quality and supported users.
