Fiber Loss Testers

Optical fiber loss testers are testing devices that integrate the functions of light sources, power meters, and VFLs. These devices have important functions such as power detection, wavelength, and frequency identification. These testers can automatically/manually determine the wavelength coming into the power meter from the light source and set them as the present test wavelength. The auto-detection wavelength feature enables the analyzers to actualize the auto-test which enhances the test efficiency and avoids issues that occur during the test. Optical fiber loss testers are regularly utilized for open field testing and lab high-accuracy measurements. They are powerful and dependable support devices for telecom workers.

Functions of Fiber Loss Testers

Fiber loss testers incorporates with modules and laser power systems. Furthermore, they can perform power testing and link loss testing in optic fiber systems. Optical fiber loss testers are used to measure the range to meet the testing prerequisite in any systems administration field. They additionally can be utilized for testing dead zones which regular OTDRs cannot do. Furthermore, these items have perfect test functions and test assurance which are perfect for indoor and field communication testing.


GAOTek’s optical fiber loss testers are small, lightweight, multi-functional, and compact. These testers likewise have color LCD display which shows full test details of wavelengths, and power states. In addition, these devices have useful features such as power detection, wavelength, and frequency identification, and after wavelength auto-detection. These devices provide dead zone test and they also have extensive capacity to store the outcomes. They can easily be associated with PCs by means of USB interfaces for information transferring, optical power calibration, and threshold modifying with the help of GAO test console software. These devices can complete the auto test, which enhances the test efficiency and brings down the mistake in the test. They have high-quality cover for protection vibration and dropping. These sorts of items work with various sorts of light source, for example, OLS1, OLS2, and OLS3.

Applications and Industries

Fiber loss testers are generally utilized as a part of the day-to-day maintenance of fiber networks, CWDM systems, DWDM systems, and FTTX networks. Fiber optic testers are utilized as a part of numerous systems for the transmission of broad bandwidth digital and analog signals and are currently used in wide area networks, local area networks, cable, communications, and telecommunications systems. Fiber optic cables have turned into the transmission medium of decision for these systems.
