Sends a red laser into the fiber and reveals breaks and leaks to the eye.
A pen type visual fault locator. Its DFB-LD laser produces a stable red light, so a break, a sharp bend or a poor splice glows from the outside. Fiber installation and maintenance teams check the line without setting up a measurement rig.

Key features
10mW
Visible marker at a distance
The DFB-LD laser runs from a constant current source and emits a stable red light.
650nm
Red light visible to the eye
Light escapes at a break or a bend, and the faulty section glows through the fiber jacket.
2 ~ 3Hz
Continuous and pulse modes
It switches between continuous light and pulse mode, and the pulse mode makes the fault point stand out.
2.5mm
Universal connector
It mates directly with SC, FC and ST connectors, and the user replaces the low loss ceramic insert.
IN THE FIELDFits in a pocketThe pen type aluminum body is light, and the technician carries it in a tool bag.
Handles impact and dustA protected laser head and the alloy housing prevent damage in field conditions.
Long battery lifeA single AAA battery runs the unit for more than 20 hours.
