FiberLert Fiber Optic Tester from Fluke Networks

Fluke Networks launches FiberLert fiber optic tester

  • Fluke announced the launch of a handheld tool capable of detecting the invisible near-infrared wavelengths (850 to 1625 nm) used in fiber optic communications.
  • The tester is intended for cable, port, polarity and transceiver troubleshooting and identifying the causes of communication failures in fiber optic networks.

Designed for one-handed operation, the FiberLert tester is a troubleshooting tool that allows users to test for the presence of near-infrared light. When placed in front of an active fiber optic port or patch cord, the tester emits a continuous light and an audible tone (when enabled).

Potential problems on fiber optic networks that carry large amounts of data can impact a large number of users. This makes it essential to resolve them quickly.

“Many network engineers and technicians need to test or troubleshoot fiber optic connections from time to time, but don’t have the tools or expertise to do so,” said Robert Luijten, training manager and test and measurement expert at Fluke Networks. “So they are forced to guess at the cause of the communication problem and replace one or more components, such as transceivers or patch cords, hoping that will solve the problem.”

FiberLert clearly indicates where the signal is present and where it is not. This allows users to identify the cause of the problem with, for example, a defective transceiver or patch cord, and replace it.

This tester supports single mode, multi-mode, UPC/APC ports and patch cords. It can perform a test without touching the port or patch cord. This reduces the risk of contamination or damage.

FiberLert’s LightBeat feature flashes LEDs to indicate power and battery status of the tester, which automatically shuts off after five minutes of inactivity to extend battery life.
