We provide a detailed analysis of the technique required to achieve double resonance, evaluate the relative intensity noise in the 0–50 kHz range (which is shown to still be below ∽-100 dB/Hz) and use the previous relative intensity noise comparison of the two sources to estimate the potential temperature/strain resolution improvement in BOTDA measurements.","PeriodicalId":269539,"journal":{"name":"2019 International Workshop on Fiber Optics in Access Networks (FOAN)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127318707","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}

It is also proposed for connecting radio units to the cloud, termed as mobile front-haul, in 5G. The most important feature of TWDM PON is a dynamic wavelength assignment scheme that can efficiently handle ONU migration from one wavelength to another to balance the traffic load. In this study, the working of DWA mechanism for ITU compliant TWDM PON is presented and an adaptive DWBA scheme is presented that can dynamically handle ONU migration in case of asymmetric traffic load conditions. The performance of the proposed scheme is evaluated through a TWDM PON test bed implemented in OMNET++ environment. For the traffic load analysis a simple regression model is used. Overall, the ADWBA scheme reduces the average upstream delays of T2 and T3 up to 28% and of T4 up to 50% with valuable reduction in bandwidth wastage.","PeriodicalId":269539,"journal":{"name":"2019 International Workshop on Fiber Optics in Access Networks (FOAN)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114712742","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}

One of the main advantages of the opto-electronic oscillator is that it produces high-frequency signals with low phase noise thanks to the resonator's properties. In most cases the opto-electronic oscillator faces the problem of generating side modes besides the oscillation signal due to non-ideal filtering. In this paper we propose a solution for the additional suppression of these undesired harmonics using a combination of two slightly detuned bandpass microstrip filters. We report an improvement for the side-mode suppression ratio about 8.3 dB with a single-loop 90-m-long opto-electronic oscillator at 10.4 GHz.","PeriodicalId":269539,"journal":{"name":"2019 International Workshop on Fiber Optics in Access Networks (FOAN)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116046115","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}

We performed an experimental verification using polarimeter and balanced photodetector for state of polarization analysis. The results show that the analysis based on polarization splitter and a balanced detector gives sufficient and comparable results to the polarimeter. In addition, it is a cost-effective solution and with the FFT it is possible to perform a quick evaluation of the event frequency.","PeriodicalId":269539,"journal":{"name":"2019 International Workshop on Fiber Optics in Access Networks (FOAN)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124698807","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}
