FlexScan with FleXpress mode plus a USB-controlled MPO switch provides what the company asserts is the fastest multi-fiber OTDR test in the industry. FlexScan also features a pocket-sized form factor, light weight, rugged package and technician-friendly ease-of-use. FlexScan can characterize an optical fiber at 1,310 and 1,550 nm in less than 5 seconds. With today's optical cables often containing 1,500 or more fibers, testing an entire cable could take more than 25 hours - double that if the network operator requires bidirectional OTDR test results. FlexScan with FleXpress mode can provide the same results in just over 2 hours.
