Fiber-optic installers and technicians rely on a broad base of knowledge to perform their jobs in the field. This knowledge is often gained through a combination of on-the-job and academic training. The Light Brigade Inc. (Kent, WA), a provider of classroom training, is now offering a new series of eight "how-to" fiber-optic videos to supplement more-formal instruction.
"Understanding and Using the OTDR" gives viewers an introduction to optical time- domain reflectometer technology and its uses. The 18-minute video explains how to use this instrument to perform an acceptance test and to locate faults or breaks in long or short runs. The video also covers the idiosyncrasies of otdrs, explaining what a dead zone is and how pulse rate affects it, how to properly calibrate the machine and why you need to do so, and the negative consequences of improperly placed markers.
Another 18-minute video, "How to Prepare Fiber Optic Cables," offers specific instructions on readying loose-tube, break-out, distribution, and armored fiber-optic cables for splicing or connectorization. The video also details how to access fibers in an active network without interrupting service.
More information on the video series is available by calling The Light Brigade at (800) 451-7128.
