:: A Little Fiber Optic History Background 1965 – Charles Kao and George Hockham showed that if optical fiber’s attenuation can be reduced to less than 20dB/km, then it can be used as a transportation media for communication 1970 – Robert Maurer, Donald Keck, Peter Schultz, and Frank Zimar from Corning made a silica glass fiber with an attenuation of 17dB/km. 1977 – General Telephone and Electronics sent the first live telephone traffic through optical fiber, at 6 Mbit/s, in Long Beach, California. 1986 – David Payne and Emmanuel Desurvire invented EDFA (Erbium-Doped Fiber Amplifier) which eliminated the need for

Automatic fiber connector polishing machines are required for high volume, high quality and consistent fiber connector polishing for fiber cable assembly houses. (fiber patch cable manufacturers). This buying guide will direct you to the perfect machine for your specific requirement. :: The 7 Guidelines for Choosing a Fiber Connector Polishing Machine In evaluating polishing machines, look for a machine that minimizes any variation in the polishing process. Variations lead to variations in the finish and inconsistent results. Current polishing machines are designed to eliminate variations in polishing and to achieve high-quality, consistent work. You should do your homework before making

:: What Is a Active Optical Cable (AOC) Anyway? Here is the brief definition of AOC: Active Optical Cable (AOC) is a cabling technology that accepts same electrical inputs as a traditional copper cable, but uses optical fiber “between the connectors”. AOC uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. A picture is worth a thousand words. Let’s look at one AOC product. The following picture shows a 40Gb/s QSFP+ Active Optical Cable Assembly from Siemon Company. Take a even closer examination and we can

:: What is Fusion Splicing? Fiber splicing is the process of permanently joining two fibers together. Unlike fiber connectors, which are designed for easy reconfiguration on cross-connect or patch panels. There are two types of fiber splicing – mechanical splicing and fusion splicing. Mechanical splicing doesn’t physically fuse two optical fibers together, rather two fibers are held butt-to-butt inside a sleeve with some mechanical mechanism. You will get worse insertion loss and back reflection in mechanical splices than in fusion splices (the second type we are introducing below).Mechanical splicing is mostly used for emergency repairs and fiber testing. You can

There are many fiber identifier products on the market by different manufacturers such as Fitel, Wilcom, Fluke Networks, etc. But Fitel’s ID-H/R LightFinder is one of the best fiber identifiers. The ID-H/R is a lightweight, hand-held tool which identifies optical fibers by detecting the optical signals passing through the fiber utilizing local macro-bending detection technology. This product comes with two components: The main unit PN AI02H. Battery, strap, and instruction manual are included. The carrying case PN AI02H-001. The case is easily to belt or tool pouch. :: How Does a Fiber Identifier Work? Simply put, the fiber identifier
