The proposed network was implemented by using only three wavelengths separated by more than 20 nm. Thus, there was no need to use any complicated wavelength-stabilization circuitry. The crosstalk caused by either fiber nonlinearities or imperfect demultiplexers was measured to be negligible. The results confirm that MFAN could satisfy all the service requirements without significant crosstalk.","PeriodicalId":176293,"journal":{"name":"2002 International Topical Meeting on Microwave Photonics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126614536","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}
