Are You Using the Right Optical Fiber? Single Mode Fiber VS Multi Mode Fiber
April 12, 2012 Leave a comment
Optical fiber is typically defined by its size, attenuation and bandwidth and it works by sending signal down hair-thin strands of glass or plastic fiber. When choosing fiber it is important to consider how it will be used. Is it device to device? Does it need to be run horizontal/intra-office (single floor but multiple rooms), rise/intrabuilding (run between floors), aerial (strung from utility poles and self-supporting), direct burial, duct, submarine or inside-outside? Determining the environment in which the fiber will be installed will help simplify the decision-making process.
The two types of fiber most commonly used are singlemode and multimode fibers. Both multimode and singlemode fibers are slightly larger than a human hair but the way light travels through the two types of fiber varies significantly.
