As the bandwidth demand and number of subscribers is increasing, WDM-PON is considered the best candidate for future deployment. On the same note, this paper presents the development of tunable 16 channels WDM-PON system, focusing on the colourless ONU's uplink signal transmission. This system is utilizing a software controlled tunable transceiver in both OLT and ONU, thus would enable colourless mode of operation. A 16 channels wavelength plan has also been defined for the upstream and downstream communication. Besides that, an athermal AWG is introduced in the network for wavelengths multi/de-multiplexing operation. An experimental setup has been made to simulate an optical modulated upstream signal from the colourless ONU to the OLT. The resulting upstream signals will be analyzed and characterized based on the availability, distance, optical received power as well as its quality on BER and the eye diagram. The results show that the ability of the developed tunable WDM-PON system to operate at 2.5Gbps for the upstream transmission and should be able to support the future plan of WDM-PON deployment in Malaysia.","PeriodicalId":243533,"journal":{"name":"2012 IEEE 3rd International Conference on Photonics","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127154983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate the use of different detection schemes namely the modified-AND subtraction detection as well as AND subtraction detection for SAC-OCDMA systems. We simulate the system performance of the mentioned detection approaches using OptiSystem7.0 software. The entire effects of fiber nonlinearities, dispersion and attenuation were considered in the simulation of SAC-OCDMA systems. Based on modified double weight (MDW) codes, the simulation results revealed that the modified-AND subtraction detection improves SAC-OCDMA system performance significantly compared to the conventional AND subtraction detection.
