The amount of useful test data that has been declared by manufacturers is, in general, not yet sufficient to allow reliability predictions to be made with full confidence, and falls short of what would be expected for new key telecom products at this stage of development and deployment. Evidence of reliable peformance of the polymers used in splitter construction when operated in damp conditions has been demonstrated. Variability in some test results has confirmed that tight control of splitter production processes is vital, both in material preparation and assembly operations. Further work is required to establish the dominant failure mechanisms in both fused fiber and planar devices.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"67 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":"131462663","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}

For the transmission of the ATM-cells flexible time division multiplexing/time division multiple access (TDM/TDMA) protocol is applied. By using a minimum number of analog components in the electronic circuitry system cost and fault liability is likely to be significantly reduced. An operation, administration, and maintenance (OAM) concept is presented considering the CCITT recommendations for BISDN point to point connections. The bit error ratio and failure conditions are monitored separately for each subscriber.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"200 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":"116502239","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}
