Fluke Networks Advances First Pocket-Size Fiber Tester

Fluke Networks has introduced the FiberLert Live Fiber Detector, a pocket-sized tester that detects invisible near-infrared (850-1625nm) wavelengths used in fiber optic communications. When placed in front of an active fiber optic port or patch cord, the tester emits a continuous light and optional tone.

Unlike more complex testers, the FiberLert requires no setup or interpretation of measurement readings on the part of the user.

“There are a lot of network engineers and technicians who need to test and troubleshoot fiber connections on an occasional basis, but lack the tools and expertise to do so,” said Adrian Young, Product Manager for FiberLert. “Hence, they are to guess as to the cause of a communication issue and replace components such as transceivers and patch cords in the hope of solving the issue.”

FiberLert™ Live Fiber Detector provides an indication that a fiber cable is live.

Versatile Tester

FiberLert removes the guesswork by clearly indicating where the signal is present and where it is not. This allows users to quickly pinpoint and remedy the cause of the problem, such as a failed transceiver or failed patch cord. FiberLert supports single-mode, multimode, UPC/APC patch cords, and ports, and can test without contacting the port or patch cord, reducing the risk of contamination or damage.

“Where I work, reconfiguring fiber patch panels is a regular chore. Unfortunately, we don’t have dedicated fiber experts,” said Stuart Kendrick, industry blogger and Systems Engineer at a Seattle biomedical research organization. “The FiberLert accelerates this process by allowing anyone on our busy team to determine if the ticket that says the pathway is no longer in use is correct. If we remove the patch cord and FiberLert tells us it’s inactive, we will safely repurpose that link. If FiberLert says it is active, we quickly plug the cord back in and note that our documentation is incorrect and needs updating.”

FiberLert’s LightBeat feature flashes an LED, indicating a powered-on condition and good battery. A timer shuts the tester off after 5min of inactivity to extend battery life. Rugged design includes a convenient pocket clip and is backed by a two-year warranty.
