Both models incorporate installed first costs (IFCs) and operations, administration, maintenance, and provisioning (OAM&P) expenses and use learning curves and inflation to trend costs. The microscopic model evaluates the economics of rehabilitation in a relatively small area, assuming fixed overall loop deployment schedules that drive cumulative production volumes and learning-curve-based costs. The macroscopic perspective, in contrast, models widespread deployment, taking into account the fact that near-term deployment decisions in many places will impact the costs of alternatives in the future.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133573545","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}
