February 19, 2013 – The Light Brigade, AFL’s education and training division, has launched what it calls the most significant upgrade to its core course in fiber optics. The Fiber Optics 1-2-3 course has been updated to feature the latest in fiber optic technology, products and standards. The accompanying 470‑page manual provides instructional material on multimode and singlemode technologies. Updates to the course and manual include: multimode fiber technology, featuring OM3, OM4 and bend-insensitive fibbers; restricted-mode and encircled flux launch conditions; singlemode fiber technology, including G.652D, G.655 and G.657 fibers; termination products and techniques; up-to-date standards and specs; FTTH, ethernet and internet protocol; expanded installation and optical testing content; active devices, including FTTx products; and information on passive devices, such as optical switches and splitters.
