The Noyes M700 from AFL Telecommunications is a compact single-mode OTDR that includes an integrated visual fault locator (VFL), an optical power meter (OPM) displaying up to three wavelengths simultaneously and a large transflective touch-screen display suitable for both indoor and outdoor operation. The M700 OTDR supports live, full-auto and expert (manual) modes, precision event analysis, dual-wavelength testing, rich file naming and an intuitive job setup functionality. In addition, specific values can be set to alert the test operator of failing or marginal events. Using one of the least squared analysis (LSA) loss methods, events may be added or deleted manually. Thousands of OTDR and OPM test results can be stored internally or on the supplied USB drive and are transferable via a USB cable or drive to a computer for viewing, printing and analyzing with supplied Windows-compatible software. Saved OPM loss values of a cable for single or dual direction can be displayed in a loss table on the M700 for evaluation and comparison. With short dead zones, a 38 dB dynamic range and greater than eight-hour battery life, the M700 is suitable for testing optical fibers in service provider metro areas.
