Noyafa Visual Fault Locator with 650nm Red Light, 2.5mm Universal Connector 10mW NF-904

The Noyafa NF-904 Visual Fault Locator (10mW) is a professional diagnostic tool engineered for telecommunication engineers, fiber optic installers, and network maintenance technicians. Emitting a focused 650nm visible red laser beam, this pen-type tester makes locating fiber breaks, excessive bends, mechanical splices, and cracked connectors fast, intuitive, and accurate.

Key Features & Highlights

• Accurate Fault Detection: Quickly spots fiber breaks, severe bends, and micro-bends by allowing visible red light to refract and illuminate fault points along the fiber jacket.
• Powerful 10mW Output: Delivers a strong optical signal capable of testing fiber runs up to 10–12 kilometers.
• Dual Working Modes: Easily toggle between Continuous Wave (CW) for constant beam illumination and Pulsed (Flash) mode to enhance fault visibility under ambient light.
• 2.5mm Universal Connector: Designed to directly interface with common 2.5mm optical connectors, including standard ST, SC, and FC fiber patch cords and pigtails.
• Rugged & Portable: Built with a durable aluminum alloy pen-style housing, making it compact, lightweight, and easy to handle during field installations and rack maintenance.

Whether you are inspecting new patch cabling in a data center or troubleshooting telecommunications infrastructure, the Noyafa NF-904 provides dependable, high-visibility optical fiber tracing.
