Fiber testers provide the precision needed to install, certify, and maintain high-speed optical networks. This category includes OLTS certifiers, OTDRs, optical power meters, light sources, and visual fault locators. VIAVI provides an advanced suite of automated fiber inspection, test, and certification tools to support accelerated fiber construction timelines. Heavy equipment digging miles-long trenches while simultaneously dropping endless spools of fiber conduit into position reminds us of an undeniable. Our fiber optic termination kits, inspection tools, and cleaning supplies allow both lab and field technicians to complete reliable assembly of fiber optic systems. Our termination kits, for example, are equipped with all of the necessary tools — pin and socket polishing tools, jacket strippers. Fiber optic cable is a type of cabling that contains one or more optical fibers for transmitting data at high speeds and/or over long distances using light. These fibers are most commonly made of glass and are very thin, typically less than a tenth of the width of a human hair. Measures distance to faults, reflectance, and total fiber loss. Crucial for certifying new links or troubleshooting existing ones.
