This in turn challenges current state of the art oscillators that provide reference signals to carry data and information as modulated sidebands. Since the frequency and spectral purity of the oscillator's output directly determines the system's data capacity, oscillators with reduced noise and increased frequency are in demand. State of the art electronics approaches fall short of meeting this demand, as losses increase with frequency, resulting in increased noise. Attempts to ameliorate the noise in oscillators with frequency in the range of 1 to 100 GHz results in complexity in circuitry, and has had limited success.","PeriodicalId":347022,"journal":{"name":"2013 IEEE Avionics, Fiber-Optics and Photonics Technology Conference (AVFOP)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132438546","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 commercially available multi-fiber MT ferrule is used in some avionic applications, but its polymer construction restricts its use to non-harsh environments. Harsh environments continue to use single-fiber, size 16,29504 termini in D38999 connectors, and this substantially reduces connection density and increases connector cost. This paper describes a novel, multi-fiber Football Ferrule™ concept under development for harsh environments in avionics. The ferrule is rugged since it is constructed of austenitic stainless steel and aligned using a metal split sleeve. Furthermore, the Football Ferrule™ increases connection density since it is smaller than the MT ferrule. The ferrule's small size allows the connection of 12 optical fibers within a single ST connector, SC connector, or multiples of 12 fibers with multiple ferrules in D38999 connectors. Additionally, the metallic ferrule might be useful as an electrical contact. Finite element analysis was used to evaluate the compliance of the metallic Football Ferrule™ and split sleeve under torsional loads.","PeriodicalId":347022,"journal":{"name":"2013 IEEE Avionics, Fiber-Optics and Photonics Technology Conference (AVFOP)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131802383","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}

Many demonstrations of RF photonic links have been made with traditional and non-traditional modulation formats [1-4] to improve the RF performance of the link. While the advantages of RF photonic links in regard to size and weight are indeed important, the large instantaneous bandwidth of the fiber optic links is a key driver for the use of this technology in the airframe. As signals of interest evolve to higher frequencies, the use of RF photonics provides a path to identify and catalog these new signals. With the acceptance of the fiber optic link as a replacement to coax, the next step is to move the photonic technology to provide signal processing capability in the optical domain before converting back to an electrical signal. The current challenges are to continue to explore new photonic technologies for improved RF performance at the receive end of the link. This paper will focus on advancements in RF photonic solutions for signal processing.","PeriodicalId":347022,"journal":{"name":"2013 IEEE Avionics, Fiber-Optics and Photonics Technology Conference (AVFOP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114482113","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}

These concerns apply to butt-coupled connectors where fibre cores are in intimate contact at a connection. Mitigation of these effects is often suggested by the use of expanded-beam technology.
