GAOTek Pen-Type Optical Visual Fault Locator

This pen style optical visual fault locator is designed for fiber optical identification and fault location and useful in the maintenance of fiber optical systems including LAN, FDDI, ATM, and telecom networks



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
