In the access domain, high capacity mmW radio systems are used as point to point links for mobile backhaul or as bridges between fixed transport networks. We demonstrate first the provision of 10 GbE compatible point to point links using OOK modulation over a 60 GHz carrier suitable for outdoor operation up to 40 m with prospects for range extension to several hundred meters. Secondly, we demonstrate the use of photonic vector modulation and demodulation for bandwidth efficient GbE LAN bridging with the potential to transmit 10 GbE at mm-wave frequencies. Finally, we demonstrate the use of photonic up and down converters for 60 GHz indoor high capacity (Gt 1 Gbps) radio generation and distribution of Ultra-Wideband signals.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130271763","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}

Selective delivery is achieved by simply controlling individual transmitter laser biases at the central office. For subscribed customers, the optimal bias condition was obtained by observing power penalty changes for the PON and OFDM signals with reference to BER of 10-9 and 10-3, respectively. For low bias levels, the OFDM signal could not be recovered. With proper band-pass filters of 1 GHz bandwidth, 4 Gbps OFDM signal can be transmitted.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"18 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120912746","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}

These optimum fibre length values have been applied to the integration of two architectures of phase noise reduction schemes: a coupled opto-electronic oscillator (COEO) with a single self-injection loop associated to a self-phase-locked loop (PLL) and a dual loop COEO. A phase noise reduction of more than 30 dB at an offset frequency of 20 kHz has been obtained for the second architecture.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122507083","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}
