Optical Attenuator

At GAO Tek, we offer a wide range of high quality and affordable optical attenuators. Fiber optic attenuators, also known as optical attenuators, are devices that are utilized to reduce or balance the power of the light transmitted from one device to another device. Attenuators are usually used when the light arriving at the receiver is too high, thus, it may overpower the receiving systems. This often happens because of problems between the transmitters/receivers or because the media converters are designed for a much longer distance than for which they are being used in such case. Sometimes attenuators are also used for testing network links by reducing the signal power (increasing the dB attenuation) until the optical links fail, thus determining the signal’s existing safety margin. The power of the signal or decibels (dB) is described as a particular distance it travels. Optical attenuators are widely used in single-mode long-haul application.

Functions of Fiber Optic Attenuators

Optical signals can be transmitted at high powers to prevent losses during transmission over long networks. However, the signal power may be too high to safely control or to use when to arrive at the receiving end. To avoid situations like that, the fiber optic attenuators reduce signal strength to levels that are acceptable by the device. Variable optical attenuators allow users to manually or automatically vary the attenuation of the signal in the fibers as it is transmitted through the devices. These devices can be used to precisely control the signal strengths in fiber circuits or to control optical signals when evaluating the dynamic range of the measurement systems. Some optical attenuators integrate the functions of both attenuator and optical power meter. Another good function of the optical attenuators is that they can memorize the attenuating values and steps and restore the values on next power up. Fiber optic attenuators are widely used for maintaining telecom systems. They also are designed to adjust the attenuation, test field, and measure the parameter of a fiber optical system. 

Features

GAO Tek’s fiber optic attenuators are portable and easy-to-use. The high-performance devices feature digital LCD screens that can display wavelengths, step sizes, current attenuations, input and output powers simultaneously, as well as battery power levels. Some optical attenuators have software that can be upgraded and contain several connector styles such as FC/PC or FC/APC to fit different kinds of fiber optic connectors. Our budget-friendly fiber optic attenuators are manufactured according to international standard and are compatible with the fiber optic products currently available in the international market.

Applications and Industries

Optical attenuators are widely used in applications such as dense wave division multiplexing (DWDM), erbium doped fiber amplifier (EDFA), and other high power applications. Furthermore, they can also be used in telecommunications systems, industrial networks, data communication networks, and voice communication networks.
