OPTON Visual Fault Locator (VFL) – 5 Meter
The OPTON Visual Fault Locator (VFL) – 5 Meter is a compact, efficient, and user-friendly fiber optic testing tool designed to help technicians and engineers detect faults and breaks in optical fiber cables. This high-precision device is engineered to deliver a visible red laser beam through fiber optic cables, highlighting problems such as breaks, bends, poor splices, or defective connectors with unmatched ease and accuracy.
Ideal for use in fiber optic installations, maintenance, and troubleshooting tasks, this VFL is a must-have for any technician working in the FTTH, FTTx, CATV, or data communication fields.
Reliable Fault Detection with Visible Red Laser
The OPTON VFL uses a 650nm red laser to provide clear, visible fault detection for up to 5 kilometers in single-mode or multimode fiber. Whether it’s a minor bend or a severe break, the bright red light quickly identifies problem areas in optical fibers, making it easy for engineers and technicians to pinpoint and fix faults without the need for expensive OTDR equipment.
This powerful laser source emits a continuous or flashing beam, allowing users to choose between stable or pulse modes based on the specific fault-testing requirement.
5-Meter Range for Effective Testing
Though compact in size, this Visual Fault Locator is powerful enough to locate faults over a 5-kilometer fiber length, making it suitable for short- to medium-distance testing tasks. It is the perfect solution for quick diagnostics in indoor and outdoor installations, helping save time and reduce downtime during maintenance or installation phases.
