All simulations were confirmed using equations found in the literature to verify the models validity. It was also verified that high voltages prevent the use of varactor diodes in NLTLs. This makes the selection for ceramic capacitors more suitable in such applications.","PeriodicalId":395359,"journal":{"name":"2013 SBMO/IEEE MTT-S International Microwave & Optoelectronics Conference (IMOC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114524450","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}

Although some landmark steps have been made in the last 10 years, Ethernet networks are not yet ready to fulfill that promise. One big issue concerns network survivability and related control functions. This paper discusses available options for Ethernet survivability focusing on protection switching and comparing them to SONET/SDH protection schemes. Then, it describes a novel approach to provide a fast automatic protection switching for Ethernet optical networks - optical Ethernet APS (OE-APS).","PeriodicalId":395359,"journal":{"name":"2013 SBMO/IEEE MTT-S International Microwave & Optoelectronics Conference (IMOC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131826905","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 new fibers are the most recent alternatives used for improving the throughput of long-haul and high-speed optical fiber networks. We compare the bit-error-rate of two orthogonal frequency division multiplexing signals, after 100 km of optical fiber, considering only its linear effects. The first one uses an 8 phase-shift keying signal operating at 130 Gbps, and the second one uses a 16 quadrature amplitude modulated signal operating at 170 Gbps. Our results show a better bit error rate performance using a few-mode fiber, compared with a two-core fiber. Additionally, Alamouti code shows a better effectiveness for compensation of linear impairments in a two-core fiber in comparison with a few-mode fiber.","PeriodicalId":395359,"journal":{"name":"2013 SBMO/IEEE MTT-S International Microwave & Optoelectronics Conference (IMOC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130124255","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}
