GAOTek Long Range Visual Fault Locator

This visual fault locator integrates the functions of fiber identification and fault locating of SM

or MM fiber over a long range.



The GAOTek Long Range Visual Fault Locator serves the purpose of fiber identification and faults locating in single-mode or multi-mode fiber. The device operates in a long range with stable power output. It is a helpful assistant to the dead zone of OTDR and is also a basic maintenance tool for fiber networks, LAN, ATM fiber systems, and telecom network systems. The use of effective laser drive circuit ensures that it can work for long hours continuously, providing stable power output in low battery.

Key Features

  • Supports both CW and 2 Hz modulation work mode
  • Use of special laser end design to avoid damage when dropping on the floor
  • Long working hours: use of effective laser drive circuit ensures that 1 mW/650 nm locator can work for more than 40 hours continuously
  • Stable power output: use of special laser driver circuit ensures stable power output in the low battery
  • 2.5 mm universal adapter: uses 2.5 mm universal adapter, can match SC/LC adapters
