Universal VisiFault Adapter 1.25 mm

The Fluke NF380 is a visible-light continuity tester built for fiber technicians who need to locate breaks in single-mode or multimode cables. It accepts both 1.25 mm and 2.5 mm ferrules, so one tool covers the common small-form-factor and standard connector sizes found in patch panels and equipment huts.

650 nm source with 80-hour runtime

A 650 nm red laser provides a bright visual fault indication that can be seen through yellow or orange jackets, letting crews trace fibers without stripping back the cable. Two AA cells deliver up to 80 hours of continuous operation, enough for several full shifts before a battery change is required.

Compact rugged housing rated for field use

The enclosure measures 6.2 by 2 by 1.3 inches and weighs 5.7 oz, fitting easily into a technician’s pouch or belt clip. It meets CSA C 22.2 No. 1010.1 1992, EN 61010-1 and CE safety standards, and operates from 0 to 40 °C with 95 % humidity tolerance, while surviving storage from -20 to 60 °C.

Questions about this item

Will the 1.25 mm adapter work with my existing 2.5 mm patch cords?

The adapter supports both 1.25 mm SFF and 2.5 mm connectors, so you can test either ferrule size without swapping tools.

How do I verify the 650 nm visible laser is operating after I insert the battery?

A bright red glow at the ferrule tip confirms the 650 nm source is active; the beam is visible along the fibre path to locate breaks.

Does the NF380 ship with AA batteries or must I buy them separately?

The tester requires two AA cells for up to 80 hours of continuous use; batteries are not included in the box.
