Jonard VFL-25 650 nm Visual Fault Locator

The Jonard VFL-25 is a 650 nm visual fault locator built for fibre tracing on multi-mode and single-mode cables. It accepts FC, SC and ST connectors and operates with a one-minute pulse duration. An IP40 enclosure protects the unit, and two alkaline AAA batteries are included. A calibration certificate can be obtained separately.

Technicians verifying fibre continuity and breaks

This locator suits installers and maintenance crews who need a handheld light source for end-to-end fibre identification and fault finding. It covers both multi-mode and single-mode measurements at 650 nm. Buyers who require an OTDR for distance-to-fault data or loss budget analysis should consider a different instrument class. Users needing a higher CAT safety rating than CAT I must look elsewhere.

650 nm wavelength and connector flexibility

The 650 nm output defines the fibre types and distances the tool can effectively illuminate for visual tracing. FC, SC and ST interfaces are supported directly on the unit. Multi-mode and single-mode fibres are both measurable within the specified pulse duration. The CAT I rating and IP40 ingress protection set the safe operating environment for the device.

Questions about this item

Does the Jonard VFL-25 come with batteries or do I need to buy AAA cells separately?

The unit includes two AAA alkaline batteries so it works straight out of the box.

Which connector type should I choose among the FC, SC and ST options listed for the VFL-25?

The locator accepts FC, SC and ST connectors; pick the adapter that matches the patch cord or bulkhead you are testing.

What does the 650 nm wavelength mean when I am tracing fibre in a real installation?

At 650 nm the red laser is visible through most jacket colours, letting you spot breaks or high-loss splices on both single-mode and multi-mode cables.
