    Information

    Main Features

    -- Starting in 3 seconds measuring immediately.

    -- Narrow event blind zone, simple test of fiber patchcord.

    -- Automatic and manual test function.

    -- High Capacity SD card.

    -- Low-power design, optical lithium battery or AA-size alkaline batteries.

    -- VFL (Visual Fault Location) function.

    -- Multiple light outputs, FC as standard ST/SC optional and exchangeable.

    -- OTDR Viewer software for data analysis.

    -- Light alarm function, preventing the device from being damaged by the signal light.

    Notes:

    ①The Specification describes the guaranteed performance with the typical PC type connector when measuring; not consider the uncertainty because the refractive index of the fiber.

    ②The dynamic range is SNR =1 the maximum pulse width within averaging time of 3 minutes

    ③Conditions for dead zone measurement: reflection strength beleow-45dB, Event Dead Zone with 10ns pulses width measurement, Attention Dead Zone 50ns pulse width measurement.

    ④Not include the uncertaint due to refraction of the fiber.

    ⑤The products with different specifications, sampling rate will be different
