Fiber Optic Test Equipment Visual Fault Locators Used in Fiber Optic Cable Testing

General information

Fiber Visual fault locators (VFL) are used for installation, fault finding, continuity checking, polarity checking, verifying a signal path, and identifying a fiber. For single mode, multimode and plastic fibers.

Pen-based visual fault locator, which use 650nm semiconductor laser as a light emitting device, through the constant current drive, transmit the red light which power is stable. After connecting with optical interface, the red light can enter into the multimode and single mode fiber, achieve detecting function of optical fiber fault. It is an indispensable tool for fiber-optic construction, fiber-optic network maintenance, optical device production and research.


  1. Maintenance in telecom , CATV
  2. Test Lab of optical fibers
  3. Fiber routing and continuity checking in optical networks.
  4. Other fiber optic measurements


  1. Locates visual faults including tight bends, breaks and bad connectors
  2. Accelerates end-to-end fiber checks
  3. Easily verifies polarity and identifies fibers
  4. Features continuous and flashing modes
  5. Ergonomic case survives drops, impacts and vibrations
  6. Supports 2.5 mm and 1.25 mm SFF connectors
  7. Over 60 hours of battery life with two AA batteries


  1. Fiber breakage, bending failure location Fault check
  2. OTDR dead zone
  3. End-to-end optical recognition
  4. Mechanical connection point optimization
