Optical Fiber Rangers

GAO Tek’s high-quality optical fiber rangers are newly designed fiber optic testers. The devices are constructed to aim at fiber network installation, fiber network engineering acceptance, and fiber network maintenance. They can be used to quickly and effectively locate fiber fault locations and are widely utilized for field use. Some of them can be used as optical fiber troubleshooter to manually or automatically detect fiber breaks and imperfections. They detect the location of the break points and the attenuation point in the optical fiber and display the result on a high-quality screen. The instruments are essential tools for technical experts to install, operate, and maintain the optical fiber. They are widely favored by professionals due to their portability, effectiveness, high-performance, and low-cost.

Functions of Optical Fiber Rangers

During the working process, the fiber optic rangers will inject the laser pulse into the optical fiber to check and collect the reflected light waves. Although the optical fiber ranger do not either display the trace of the fiber or give any information about the fiber and event losses, they can identify types and locations of both bases on a set of pre-determined threshold values and go throughout the entire length of the fiber under test. The instruments are high-performance testing meters which are mainly used for the daily maintenance, fault location, and detection of the optical network system.


GAO Tek’s optical fiber rangers are some of the most portable and reliable test instruments in the industry. They adopt the OTDR technical principles and integrate the powerful analysis software, which enables the fiber rangers to detect fiber faults more accurate and easy. The instruments often come with a large LCD display and a long-lasting battery which can endure up to numerous hours. All these features make the testers perfect tools for the field work. GAO Tek’s cost-effective and easy-to-use fiber rangers are ideal instruments for the fiber cable construction and maintenance.

Applications and Industries

Optical fiber rangers are widely used to examine the distance of the fiber and identify the faults location in the fiber link. They can also be used to locate reflective and non-reflective breaks in the fiber network Inspection of fiber repair and maintenance. Fiber ranger are designed for the FTTx network installation and maintenance. Moreover, they are suitable for WAN, LAN, metro LAN, CATV and etc.
