The efficient power supply circuit can provide stable power. 2.Metal matte paint design The stainless steel head and aluminum-alloy body design are used to prevent collision and dust, and the chassis grounding design effectively prevents electrostatic discharge damage. 3.Widely Used The 2.5 mm universal connector of the detector is designed for ST, SC, and FC compatibility, and can interfere in different circular and square optical cables. Test single-mode and multi-mode cables. 4.Practical design, excellent function Small size, lightweight, easy to carry, has a variety of functions such as constant output power, low battery power alarm, long battery life, long-distance detection, etc. Tips 1. When not in use, remove the battery to prevent battery leakage, which can cause aluminum parts to oxidize and not conduct electricity. 2. This pen cannot be directed into the eyes. Pen type design, with eye bags, easy to carry, easy to check optical fiber fault with visual fault locator, sturdy and durable, dustproof design, keep optical fiber connector clean.
Product Features
- 1. Easy to Check Fiber Faults - This 50mw visual fault locator can accurately detect and locate fiber breaks, poor connections, bending, or cracking. The detector will emit a 650nm bright light for fiber tracing, breaks or faults in the fiber will refract the light.
- 2. Excellent Function - This VFL device is portable and easy for a field test with multiple functions such as constant output power, lower battery warning, long battery life, and long-distance detection.
- 3. WIDELY USED - 2.5mm Universal Connector - the connector of the detector is compatibly designed for ST, SC, FC interferes both in circle and square shape of different fiber optic cables.
- 4. LONG OUTPUT DISTANCE - This visual fault locator with battery output strong red light goes 40-50 kilometers far, high effective power circuits allows for stable power.
- 5. Practical Design - Small size and lightweight, pen-type design with pouch make it portable, easy to check fiber faults with visual fault locator, design with a stainless steel head and aluminum body to prevent crash and dust, the case ground design prevents ESD damage efficiently.
