Switching between the two functions can be realized by adjusting the DC bias of the second PolM. An experiment is carried out. OSSB modulated signals with an operation bandwidth from 5 to 35 GHz are achieved and two OSSB modulated signals with tunable OCSRs from -26 to 46 dB and from -25 to 55 dB are demonstrated. When the system is switched to be a microwave photonic phase shifter, a full 360 degree phase tuning range can be realized. The proposed scheme features a compact structure and dual switchable functions, which may find applications in microwave photonics.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122896865","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}

We use the service level agreement (SLA) soft threshold model to avoid frequent peak migrations at the migration trigger point. In the source virtual machine selection process, the maximum relevance is considered during the virtual machines selection method to improve resource coupling. In the destination server selection, the multi-resource relevance and matching method is used to solve the coupling problem of a single resource and the matching problem of a variety of resources. The simulation results show the proposed algorithm can improve the utilization rate of server resources to reduce power consumption and ensure system stability by reducing migration times. We also show that compared to existing techniques the algorithm used in this study can better adapt to dynamic changes of workloads.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128880362","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}

When the total input power is less than 4mW, the crosstalk effect can be neglected, otherwise when the total power is more than 20mW, the crosstalk is very obvious.

Compared with the traditional telecommunication, optical communication is regarded as a kind of secure communication because optical fiber, transmission medium of it, is immune to the typical issues of electromagnetic interference (EMI)/radio-frequency interference (RFI). However, the essential characteristics of the optical fiber make it vulnerable to a variety of attacks, including physical infrastructure attacks, eavesdropping, interception, and jamming. In this paper, we proposed a new model to inject the light into a communication fiber without damaging the cladding or core of it. From numberical calculation, the power of injected optical signal can reach to more than 20% of the input power. This level of injected signal is sufficient to interfere with the signal transported in the communication. So measures to combat this kind of inference and deception should be taken.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116898911","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 CapEx of high-capacity optical network under given traffic requests is optimized, and results are analyzed to evaluate the influences of Multi-core Fiber (MCF) communication system on the components of optical network CapEx. To solve the optimization problem, network CapEx is modelled and an integer linear programming (ILP) formulation is proposed. Numerical results show that by using MCF communication system, optical network CapEx can be reduced significantly. The cost of OA takes the largest proportion of the network CapEx, and can be reduced by deploying MCF communication system to optical networks. Fiber density can be increased by using MCF, thus decreasing the costs of cable and conduit.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128079799","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}

AOPS is adopted for processing burst services and enhancing switching efficiencies, and the ring-mesh hybrid interconnection can improve the datacenter scalability with survivability function. Optical switching array and all-optical tunable delay lines (AOTDLs) are used to resolve contention, to reduce system time delay and packet loss ratio (PLR) as well as to enlarge throughput. Distributed control management alleviates the pressure of computing and storing. The simulation models for PLR and time delay in the datacenter are set up, which have been approved to be efficient in the asynchronous variant self-similar traffic. And the PLR increases with increasing traffic load while decreases with the larger buffer granularity and time delay increases with increasing traffic and the larger buffer granularity.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124507808","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}
