Product Description

650nm Pen-type Visual Fault Locator

Pen-based red light source, 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.
