The designer is introduced to the limits that attenuation and dispersion place on single-hop system designs. A distributed feedback (DFB) laser spectral width of 1 nm (including chirp) is assumed throughout the examples of digital systems transmitting at 2.4 gigabits per second (Gbps). External modulation may be used to reduce source spectral width and extend the results presented. An optically amplified system schematic diagram is presented. The examples include calculations for maximum span length using a single optical amplifier and maximum route length for amplifiers in cascade.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"33 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":"116153715","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}

Some of the advantages of using PON-based systems in deployment scenarios traditionally associated with other technologies are presented and discussed. The use of teleconferencing over a PON (TPON) equipment to serve larger customers and to provide service over other transmission media may be beneficial. Such deployment would help to rationalize the range of equipment in use in the network, simplify management and maintenance procedures and reduce the range of equipment spares held. The development of a compatible modular range of units that could be used to provide services to a wide range of market segments in many different geotypes is illustrated.","PeriodicalId":104930,"journal":{"name":"Proceedings of 5th Conference on Optical Hybrid Access Networks","volume":"47 17 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":"122772648","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}
