With two pumps in FRA, we can get a flat gain spectrum, whose gain ripple is 1.6dB and range is from 1530nm to 1558nm, by using this method.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"18 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":"129758415","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 OFDM-PON, power efficiency is one of important topics attained extensive attentions because the access network is a main power contributor in the whole infrastructure. The previous works focused on reducing the power consumption of OFDM-PON in the Media Access Control (MAC) layer. In this paper, we investigate the joint optimization of bit and power loading for saving power consumptions in the OFDM-PON from the algorithm level perspective. With the constraints of the total bit rate requirement and the acceptable Bit Error Rate (BER), we aim to minimize the transmitted power of ONUs in the OFDM-PON. We transformed this problem into a mathematic model, and then we proposed an efficient algorithm to jointly optimize the bit and power loading, according to our model. Simulation results demonstrate the performances of our proposed algorithm.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"22 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":"125164582","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}

Due to the development of space-division multiplexing (SDM) technology for fiber transmission in FMF, the nonlinearity in FMF has attracted significant research interests recently. Analogous to single-mode fiber, nonlinear effects may eventually limit the information capacity in FMF transmission systems. In this paper, we first reviewed the past and current research in this area. The paper then concentrates on the theoretical and numerical investigation of inter-modal four-wave mixing (IM-FWM) among up to four spatial modes in FMFs. Different forms of multi-mode non-linear Schrödinger equation (MM-NLSE) for two, three and four spatial modes are derived, along with up to twelve types of wave/mode distributions and their corresponding phase matching conditions. We analyze the mixed effects of differential mode group delay (DMGD), chromatic dispersion (CD), random mode coupling (RMC) and wavelength separation upon IM-FWM efficiency in FMF. In addition, intermodal nonlinear effects in FMFs may potentially provide a variety of innovative optical signal processing functionality for fiber network applications through this additional spatial dimension. For example, we show simultaneous mode and wavelength conversion based on IM-FWM, and explore the effects of group velocity dispersions in order to achieve higher conversion efficiency.","PeriodicalId":364683,"journal":{"name":"2014 13th International Conference on Optical Communications and Networks (ICOCN)","volume":"53 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":"116216205","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}
