GAOTek Pen-Type Optical Visual Fault Locator



The GAOTek Pen-Type Optical Visual Fault Locator is used for optical identification and fault locating in single-mode or multi-mode fiber, which makes it an ideal maintenance tool for optical networks, LAN, FDDI, ATM optical systems, and telecom network system. It has a 650 nm visible laser source which transmits continuous light or 1 Hz modulated light into a fiber, allowing the user to visually detect any fiber fault over distances of up to 4.9 mi (8 km).

Key Features

  • Identifying fiber breaks, bend, splices and other loss fault
  • Large power up to 650 nm red laser
  • Transmitting continuous light or 1Hz modulated light
  • Pen-shaped design, small size, light weight, easy to use
  • Powered by standard AA alkaline batteries
  • 5 nm universal connectors
