Visible Laser Source

This handheld visible laser source, model GAO C0280003, features low voltage warning, auto power-off, simple button operation and an energy-saving design. It uses visible red light to indicate the location of fiber faults from a macro bend point, break, problem coupler or connector or a mechanical splice that is not well aligned. It can distinguish the faults in fiber jumpers, jumper boards, distribution frames and tie-ins. Its working wavelength is 650 nm ± 20 nm. It offers FC, ST and SC adaptors. CW and 2 Hz alternative optical output modes are also available. This laser source overcomes the usual limitation of the dead zone of an OTDR to accurately detect fiber fault positions. In addition, it is powered by a 9 V/160 mAh NI-MH rechargeable battery which provides continuous operation of 8 to 10 hours.

This handheld visible laser source belongs to GAO’s family of Visual Fault Series. This line of products also includes a wide variety of visual fault locators such as Optical Visual Fault Locator, Pen-Type Visual Fault Locator and Rugged Visual Fault Locator which is widely used for fiber optic network maintenance in telecommunications and CATV systems.
