To meet customer service objectives and to minimize operations, administration, maintenance and provisioning (OAM&P) expenses, a focused technology deployment strategy is necessary. Optical network unit (ONU) deployment to better meet service requirements and business customer needs is discussed. Modernizing the access network can be performed through one of the pre-defined ONU technology deployment alternatives. Each of these deployment plans have their merits relative to the economics and the OAM&P savings. A prioritization process is mandatory in order to optimize network deployment plans and investments. The utility of utilizing ONUs for business modernization is demonstrated. There are opportunities in small, medium, and even large business applications.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"36 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":"115593776","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}

Before fabricating the 1 /spl times/ 8 star coupler, total insertion loss and loss uniformity are estimated, and seven 2 /spl times/ 2 fused couplers are selected. A high performance 1 /spl times/ 8 star coupler is achieved based on this estimation.

Two upgrade architectures for providing multichannel digital video services as an overlay in a narrowband fiber-to-the-curb (FTTC) system with eight living units (LUs) per optical network unit (ONU) are investigated. The upgrade provides video subscribers with access to switched channels and to a menu of 140 multicast or broadcast channels, all digitally compressed to 4 Mb/s per channel. One of the upgrade architectures transports video channels in asynchronous transfer mode (ATM) cells using a wavelength division multiplexing (WDM) overlay from the host digital terminal (HDT) to upgraded ONUs, with coaxial drops to set-top converters at the customer premises. The alternative architecture uses subcarrier multiplexing (SCM) technqiues to transport video channels in 16-quadrature AM (QAM) format to video ONUs (V-ONUs) each serving 64 LUs through a coax-bus distribution.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"66 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":"116615324","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}

Standardization can proceed without reference to the time compression multiplex (TCM). Similarly, by judiciously organizing exchange equipment (OLT) and user equipment (ONU) functions, network interfaces and optical transmission can evolve separately and broadband services can be accommodated progressively. The multispeed frame principle remains the cornerstone of the system given its suitability for matching equipment to applications and to different categories of user. It is also a good basis for future standardization in that it affords a high degree of openness in the definition of specifications. Economic parity of the optical systems in fiber-to-the-home (FTTH) distribution is contingent on the development of new and integrated optical components.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"3 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":"117120654","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}
