MAY65 Mini VFL Visual Fault Locator 650nm 5mW 10mW 20mW 30mW 50mW with 2.5mm adapter for single mode and multimode fibers


SKU: N/A Category:

MAY65 Mini Visual Fault Locator totally complies with the human engineering. It’s small in size, easy to operate, portable and integrated with a launching indicator. A Visual Fault Locator is usually used to inspect the damaged or broken point of an optical fiber, cable, patchcord and etc. If the inspected fiber does have a defect, users could find the visual laser at the broken or damaged point.

MAY65 Mini Visual Fault Locator is suitable for both single mode and multimode fibers. The performance of the visual laser source will act a little different on different fiber coat and color.


  • Totally comply with the human engineering design. Small, portable and durable
  • Standard multi-adaptor can be applied to connect with almost any adaptor type. Also provides interchangeable fiber adaptors of several common types
  • High output laser power
  • Integrated with continuous wave and 2Hz modulated wave output function
