It is also financially viable for the telecommunication service providers, particularly in rural areas. In order to successfully integrate the two technologies, there are some technical concerns in terms of Architectural aspects, Physical Layer features and Media Access Control (MAC) related issues. This paper is mainly focused on the analysis of the key topics in architectural design of the converged scenario such as ETE module specifications as well as the MAC-related issues such as ETE resource allocations between the hybrid Passive Optical Networks (hybrid PONs) and wireless technology. A semi-independent structure for the architectural design of the converged protocol is proposed in this paper along with the ETE functional modules from the Optical Line Terminal (OLT) at the far-end Central Office (CO) all the way to the SSs at the front-end customer premises. The ETE key functional modules, which provide the MAC-related issues for the converged protocol such as ETE resource requests and allocations, are also highlighted.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132001535","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 traditional technologies used in the backhaul, copper, radio links and optical fibers, either cannot offer high data-rate, or are expensive. In this paper, we propose mixed integer programming models to facilitate upgrading the cellular backhaul using the free space optical (FSO) technology, a cost-effective and high-bandwidth solution. Since the optical signal is transmitted along line-of-sight and FSO links are sensitive to weather conditions, we incorporate mirrors in the models to provide alternative paths for pairs of FSO nodes without line-of-sight, and increase the path diversity to enhance the resilience. Optical fibers existing in the backhaul are considered in the models and reused to decrease the upgrading cost and improve reliability. The presented models can deliver topologies for various requirements on cost and resilience. They can also be used to develop topology planning and optimization tools.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125406717","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 topology includes the use of a dual drive Mach-Zehnder modulator (DD-MZM) to realize Remote Heterodyne Detection (RHD) and Wavelength-Division Multiplexing (WDM) to separate both modulated optical signals. At the receiver station, an offset launch is applied at the junction where SMF is coupled with MMF to improve the signal bandwidth by applying Offset Launch theory. The transportation of mm-wave wireless signals within radio-over-fiber network causes impairments on the signals, some of which are fiber modal and chromatic dispersion. In this paper, we apply such a unique theory that increases signal bandwidth by mitigate the pulse broadening witnessed on a signal as a result of modal dispersion in the Multimode fiber.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126869420","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}

Variable composition and refractive index, in addition to background light, are highlighted as aspects of the channel which advanced models must represent effectively. Models are assessed against these aspects in terms of their ability to predict transmitted power and spatial and temporal distributions of light a specified distance from a transmitter.

It is shown that PPM is more resilient to Inter-Symbol Interference (ISI) induced by multipath channels when one array of Light Emitting Diode (LED) transmitters is employed compared with OOK schemes. However, the OOK arrangement is capable of outperforming the PPM counterpart in a highly diffused channel. More explicitly, the effect of ISI on BER performance fundamentally determined by the interplay of the delay spread of the indoor wireless channel and the duration of one transmission symbol, which is captured by `normalized delay spread'. Finally, numerous simulation results were provided in order to demonstrate the system performance under various normalized delay spreads.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132602948","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 transmitter has a high power efficiency, so the communication functionality does not lead to significant power consumption. For this reason, a Trans-Conductance Amplifier (TCA) was designed making use of a class AB amplifier. The final design has an electrical bandwidth from 20 kHz until 25 MHz and is able to power LEDs with a driving current up to 700 mA. Results show that the bandwidth of the driver electronics is much larger than the bandwidth of the commonly used power LEDs that are designed for illumination purposes. Because the transmitter has the ability to implement different modulation techniques, as well digital as analogues in nature, it can be used in a wide range of applications depending on the needs of data rate and bandwidth.","PeriodicalId":134436,"journal":{"name":"2013 2nd International Workshop on Optical Wireless Communications (IWOW)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125371761","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}
