However, the gain bandwidth of usual fiber amplifiers is limited to a maximum of 80 nm in the C- and L-band. Todays optical senders and receivers are limited to a spectral efficiency of not more than 1 bit/s/Hz which results in a total capacity of about 10 Tbit/s in the C- and L-bands. Meanwhile the crash of the telecom market damped the bandwidth growth somewhat, but it is still an important task to work on solutions for transmission systems at extremely high bitrates beyond 10 Tbit/s. One of these solutions is the use of larger parts of the low attenuation window of the transmission fibers. It seems to be consensus that the first step towards this direction will be the S- and S/sup +/-band at 1450-1530 nm. Here we will give an overview of the current status and new developments in the field of S-band fiber amplifier technologies. As usual, the term S-band will be used for Sand S/sup +/-band in this work.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123915454","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}

The presented optically transparent network represent a novel approach in fiber-to-the-desk applications. It is made to minimize the costs associated with a passive optical LAN implementation. The biggest issues in the realization of the network are the synchronization of bursty traffic and collision detection. We present, in detail, the solution to the synchronization problem by introducing an analog sinusoidal carrier that is in addition to the data signal only sent within the data packet duration. The extraction of data and the synchronization signal is made by using simple filtering, facilitating the receiver realization.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132079503","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}

Towards a dynamic hierarchical cross-connecting without wavelength conversion in multi-fiber WDM networks 多光纤WDM网络中无波长转换的动态分层交叉连接

The HXCs implement an optical bypass, at coarse granularity using the wavelength banding technique with waveband cross-connects (WBXC), and, at fine granularity, using wavelength cross-connects (WXC). Reducing the possibility of fine granularity switching results in reducing the OXC complexity at the expense of increasing the blocking probability. In particular, we do not allow the use of wavelength converters in order to reduce the global cost further. Two parameters, /spl mu/ and /spl beta/, define the optical node architecture with a calculated complexity reduction ratio and a simulated blocking probability. Fixing a maximum blocking probability and a minimum complexity reduction results in choosing /spl mu/ and /spl beta/, and hence the node design, for a maximum given traffic load.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133300584","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}

Introducing automatic switching capabilities in optical networks means designing and implementing control functionalities. Such functionalities are hosted at the network control plane, and mainly consist of providing signalling and routing mechanisms distributed throughout the network. The paper addresses some issues still under discussion on the definition of a suitable control plane for optical core networks. Specifically, we deal with the routing protocol, which defines the distribution of topology information, the path selection and the association of nodes in a network; and with the routing mechanism, which allows selection of the path according to the attributes of connection requests and the available resources in the network. We also deal with the traffic engineering strategies used to optimise the use of these resources and give a quick view of future trends in optical networks.","PeriodicalId":272700,"journal":{"name":"Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003.","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115831334","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}
