    Fiber Checker Pro with Adapter

    The TL4-4402 Fiber Checker Pro is used for checking the defects of a fiber cable. It sends a visible 650nm wave length red laser light through a fiber optic cable, the breaks or faults in the fiber will refract the light, creating a bright glow around the faulty area.

    The universal connector can be used for the most common fiber interfaces such as ST/SC/FC/FDDA. It is suitable to test both single mode and multimode cables. With an optional 2.5mm to 1.25mm adapter, users can even test for 1.25mm fiber cables. The visibility is up to 5 kilometers.

    There is also specially designed power circuit included; it provides steady power which avoids unstable laser output when the battery is low.

    The output signal can be switched between CW or Pulse mode to get different visual effects. There is a dust proof cover which will prevent dust from getting into the inside of the interface. The cover also helps avoid incidental exposure of the laser to your eye.
