Light Sources

GAO Tek provides a large collection of high quality and reliable light source testers. Fiber optic light sources are designed to transmit signals from one place to another. These are the modern techniques for detecting light sources with optical light source testers. Fiber optic light sources can be used for transmitting light from a source to a remote location for illumination as well as communication. In fact, fibers are made to not only transmit lights but to glow along the fiber itself, so it resembles a neon light tube. Applications for fiber optic lighting are many, generally based on utilizing the special attributes of the fiber as well as its unique characteristics.

Functions of Light Sources

GAO Tek designs optical light sources for the installation and maintenance of fiber optic cables. Some of these products can transmit wave ID information with specific optical power meters. These devices can be covered with different wavelengths to meet with specific requirements such as single mode or multi-mode. Light sources can be used in conjunction with other types of test equipment such as optical power meters and fiber identifiers for testing the fiber optic cables. The light sources can transmit with a wavelength-identification digital encrypted protocol, so that any compatible unit—the Power Meter and the Optical Loss Test Set—can automatically use the proper calibration parameters. They reduce the need for communication between the two technicians and decrease the potential of errors.


GAO Tek’s fiber optic light sources can give quick and accurate testing results. They can operate with different frequencies so it is easy to operate. These products usually have several fiber ports so they can be used with different patch cords. Light source devices give high accuracy and reliability to evaluate a wide range of optical devices and systems. These products usually have intelligent backlight controls so it is easy to work at night or in a dark place. They also have LCD displays to view the output power values. These products can operate with AC and DC power supply with a long lasting battery life. Moreover, they have low battery indication so technicians can identify and arrange power as needed. The devices are lightweight which make them portable and very easy to use. Light sources can operate in standard minimum negative and maximum positive average temperature so they can be used in most country environments.

Applications and Industries

Light source devices usually are used in LAN, WAN for the purpose of telecommunication networks, CATV systems, and long distance optical networks. In fiber optics, light sources are used to emit electromagnetic radiation in order to perform a specific task, whether detecting faults, breaks and microbends, characterizing link-loss or certifying LAN/WANs.
