Multi-class sensing recognition is important in optical fiber distributed vibration systems, since accurate detections on the vibrations can significantly improve the performance of the systems in ...

Vi ska nu fixa bättre wifitäckning som ska täcka samtliga delar av hus och tomt. Inkommande fiber är mitt i huset på andra våningen. Kabel dragen till första våningen med en switch. Gula markeringen ...

A model for the shape of optical fiber tapers, formed by stretching a fiber in a heat source of varying length, is presented. Simple assumptions avoid any need for the techniques of fluid mechanics.
