OLS1 LED Light Source


  • Cost effective – LED Source

    NOYES OLS1 from AFL is two port multimode LED source for testing multimode fiber links.  Packaged in a rugged hand-held case The OLS1 is designed for technicians on the go.  The LED output is stabilized to ensure accurate test results per current TIA/EIA requirements.

    Low Training Requirements: The OLS1 is easy to operate with only a [Wavelength/ Power] switch, which selects optical wavelengths or disables unit.

    LED indicators [Active Output], [Battery], and [External Power] identify the currently enabled output port, battery level, and external power presence.

    Weighing only 0.65 lb, the OLS1 is compact and convenient for field use. The OLS1 from AFL operates over 60 hours from a typical 9V alkaline battery. An AC adapter is optional for extended use.

    50 and 62.5 µm fiber mandrels Included

    Mandrels condition test cable for use in certifying both 50 and 62.5 µm fiber links for current and planned high bit rate applications including Gigabit Ethernet and 10 Gigabit Ethernet.  Mandrels apply to launch jumpers is seconds without tools and ensure loss measurements comply with TIA/EIA-568-B standard.

    The OLS 1 light source is fully N.I.S.T. traceable.
