Lennie Lightwave's Guide to Fiber Optics. Lennie Lightwave's Guide to Fiber Optics fiber optics,transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber is an online tutorialthat includes basic information on fiber optics and virtual hands-ontermination training. The website recently added new web tutorialscovering optical time domain reflectometers (OTDRs) and loss testing ofcables with an optical loss test set (OLTS OLTS Optical Loss Test SetOLTS On Line Tracking System (EPA)OLTS Organizational Level Test Set ). Both tutorials were writtenby Jim Hayes of VDV VDV Verband Deutscher VerkehrsunternehmenVDV Verband Deutscher Vermessungsingenieure eV (Germany)VDV Vozdushno-Desantnye Voyska (Russian Federation Airborne Forces)VDV Voice Data Video Works, who is also president of the Fiber OpticAssociation. According to Hayes, OTDRs have been used for many years in outsideplant installations and are becoming more common in campus and premisesnetworks, but most installers are not familiar with them, nor are theyaware of the subtleties of interpreting the OTDR (Optical Time Domain Reflectometer) A test instrument that analyzes the light loss in an optical fiber. Used to find faults, splices and bends in the line, it works by sending out a light pulse and measuring its reflection. display. The newtutorial is intended to help make OTDRs easy to understand. The tutorial on OLTS explains how an OLTS (or fiber optic sourceand power meter) is used. Hayes notes that every fiber optic cable Noun 1. fiber optic cable - a cable made of optical fibers that can transmit large amounts of information at the speed of lightfibre optic cabletransmission line, cable, line - a conductor for transmitting electrical or optical signals or electric power mustbe tested for loss by this method and says that his tutorial describesthe process in an easily understandable language accompanied byillustrations and a step-by-step process.
