For broadband amplification it is used, because of low noise and better gain. Raman amplification was investigated in multiple views.

In this paper, Raman amplification is studied in the views of varying Refractive Index profile of core, varying core gap radius, hybrid combination of RA with Erbium Doped Fiber Amplifier (EDFA). This paper also studies the investigations of this hybrid combination in Dispersion compensation at C and S bands, recycling of pump power and location of EDFA.","PeriodicalId":41375,"journal":{"name":"3c Tecnologia","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49128701","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}
