The backbone of the suite fashioned out of these modular building blocks is the fiber-optic bit-serial time-division multiplexed high-speed data bus (HSDB), operating at 50 Mb/s, which provides command and control communications among most of the aircraft subsystems and can be used to provide communications for a fly-by-light flight-control system or for the block transfer of data between mass memories and data processors. The fiber-optic HSDB is examined from the top down, beginning with an overview of the evolution of avionic architectures. A review is given of the standardization activity associated with development of the network, the protocols chosen to implement the desired communication functions, configuration options, and the fiber-optic components used in the bus interfaces or other active nodes of the network. It is believed that the utility of the bus extends beyond aircraft to spacecraft, ships, and land vehicles.<<ETX>>","PeriodicalId":138128,"journal":{"name":"IEEE LCS","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129625433","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}

Interferometric, acoustic, magnetic, fiber gyro, and intensity-based sensors are considered, and multiplexing arrays of sensors is discussed. The main thrust of the program has been sensors for antisubmarine warfare. Applications include the all-optical towed array (AOTA), fiber-optic planar arrays, bottom-mounted acoustic sensors, magnetometers for fiber-optic magnetic arrays, and rate-of-rotation sensors for attitude, heading, and navigation systems. These require the high sensitivity and performance of phase-based or interferometric sensors. Other applications that can be satisfied with the simpler, less sensitive intensity-based sensors include damage control sensors being developed for shipboard applications and fly-by-light systems for military aircraft.<<ETX>>","PeriodicalId":138128,"journal":{"name":"IEEE LCS","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129069763","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 potential utility of optical fiber bandwidth as a means for reducing the complexity of expendable missiles by transferring data-processing functions from the missile to the launch platform is discussed.

PIC technology replaces the separate, sequential alignment of single-mode fiber interconnections between the discrete devices with lithographically produced single-crystal waveguides, eliminating the cost of individual alignments through a wafer-scale batch process and providing a lower-loss connection, a low-reflection connection, and a very robust, small package. To illustrate the application of PIC techniques, a balanced heterodyne receiver, a wavelength-division-multiplexing source, and tapered waveguide output couplers are considered.<<ETX>>","PeriodicalId":138128,"journal":{"name":"IEEE LCS","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132533854","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}
