NK126 Series Fiber Optic Visual Fault Locator (VFL)
- Satisfaction guarantee
- Fast delivery
- Quality assurance
Description
The NK126 Series Fiber Optic Visual Fault Locator (VFL) incorporates a high-power 650nm laser diode as the light source, delivering an output power of over 15mW. It is suitable for both single-mode and multi-mode fiber measurements, used for detecting fiber connectivity and locating faults such as fiber breaks and bends. Equipped with a high-capacity 18650 rechargeable battery (2200mAh), it offers extended continuous operation time. The circuit features over-current, over-voltage, and over-discharge protection mechanisms, effectively safeguarding the battery and charging circuit.
The device utilizes a universal adapter as the output interface, compatible with various connectors such as FC, SC, and ST without the need for additional adapters. This makes it convenient for testing various fiber optic patch cords, ribbon or bundle pigtails, making it an ideal tool for construction sites and fiber optic line maintenance.
