What is an optical attenuator?

6 The signal intensity is described in decibels at a specific distance that the signal travels. It is a power or amplitude of a signal that changes and not the overall shape of the wool or frequency, so the optical signal remains unintegrated for use in the desired application. Optical athenurators are often used in optical communication systems in which the attenuation, also called transmission losses, helps to transmit digital signals over long distances. Among the most common types of optical attenuator are solid and continuously variable attenuators. Officials installed elsewhere along the optical fiber do not reduce the power of the signal sufficiently, but some devices use the signal absorbs or reflects components for compensation. The optical fiber connector is often connected to an optical attenuator, which usually has an adapter with female configuration. The attenuator itself usually has a cylindrical or even box structural shape that determines the type of device in which it can be installed.

Fixed diversity of the optical attenuator, sometimes found in the electronic circuit, does not reflect light signals to reduce their intensity. It is generally used where data transfer must be high. The function of the device is determined by the amount of energy that it can handle, except for important variables, such as the performance versus temperature and frequency range. Most optical athenurators use resistors, but a variable optical athenurator uses transistors of the field effect of a metal semiconductor or other firm components. The attenuation is adjustable, so signals in the optical fiber communication system can be changed to suit the fluctuating performance levels and protect the system from damage.

Variable optical athenurator can be mounted on a circuit board or used in test devices such as an optical power meter. Many attenuators are installed in-line with an optical fiber cable to make the corresponding ZPEdit the transmitted signal. They sell them many retailers and manufacturers online, so it is possible to assess their properties by reading the product specifications. Aspects that need to be considered include the diameter and high -end power that the device can tolerate, how much the attenuation it provides, as well as its overall dimensions and type of environment in which it can work.
