Conventional OFDMA systems require power-consuming IFFT in the transmitter. It will be shown that “Green” can be realized in the generation of IFDMA signals by replacing the IFFT circuit with a simplified subcarrier mapping circuit. “Elastic” bandwidth provisioning will be demonstrated by the uplink experiment of dynamic allocation on-demand of 20 Gbps-QPSK and 30 Gbps-8 PSK signals to two ONUs. In addition, the carrier synchronization technique of the uplink between multiple ONUs by using DSP-based low-complexity carrier frequency offset (CFO) pre-compensation will be discussed.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975965","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}

In the hybrid system, OOC is employed as users code sequence of the OCDMA dimension. The simulation results show that the hybrid system presents better performance than the 2-D WHTS OCDMA system, and show also that under a standard BER scenario, i.e., BER = 10-9, the hybrid system can support at least 75% more simultaneous users than the 2-D OCDMA system for the analyzed case study. The analysis suggests that the hybrid 1-D WDM/OCDMA system is a qualified migration scenario since it can provide a smooth migration path from current networks towards OCDMA networks.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126977195","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}

This allows the use of Markov chains to perform availability analysis of connections routed in the optical network. However, the times-to-repair may be better described as Weibull distributed random variables, thus preventing the use of Markov chains. This paper investigates the impact of the time-to-repair distribution on the interval availability of a connection in an optical network. The exponential and the Weibull assumptions are compared. By computer simulations, and considering the case study of a connection routed in an American network, we identify the cases where the Weibull and exponential assumptions yield similar or distinct results.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129079292","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}

Polarization analysis showed that an optical beam linearly polarized at the multimode fibre input changed to elliptically polarized after propagating down the fibre and the result was compared with a standard silica optical fibre. However, the elliptical distribution remained unchanged with or without applied magnetic field, demonstrating that no circular dichroism occurs within the fibre. The Verdet constant values of the tellurite bulk glass diverged by less than 3% from the values measured on the fibre whose core had the same composition of the bulk glass. The results of the investigation demonstrate that tellurite glass fibres obtained by preform drawing are suitable for developing devices for magneto-optic applications.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123354628","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 effect is especially strong for the anomalous dispersion regime where an interaction of GVD and self-phase modulation (SPM) leads to formation of high-order solitons. The irregularities of the resulting NALM transfer functions can be used for phase-preserving amplitude regeneration of several, irregular-spaced amplitude states for multi-level modulation formats. The regeneration performance was estimated for a 16QAM signal with three amplitude states where a reduction of amplitude noise without significant signal phase distortions has been observed.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123507650","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}

However, their usefulness is limited by a low angular tolerance that requires the use of collimated beams. Following the proposal from Ura et al. [1], we demonstrated small aperture resonant grating filters with a high modal reflectivity (larger than 60%), a narrow linewidth (1.5 nm at 850 nm) and a large angular tolerance (larger than 9, FWHM) [2]. In this paper, we discuss the design and performance properties of such filters, and demonstrate spectral stabilization of a laser diode with resonant grating filters.","PeriodicalId":217442,"journal":{"name":"2012 14th International Conference on Transparent Optical Networks (ICTON)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123529025","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}
