Attenuation is known as transmission loss in fiber optics. With respect to the distance traveled, it is the reduction in light signal intensity by the signal in a transmission medium. To limit the transmission of a digital signal traveling in large distances, Attenuation is an important element. As it travels along with free space or optical fiber, an optical attenuator reduces this optical signal. The fiber splitter is very reliable. When used in fiber-optic communications, Optical fiber attenuators may employ several principles. The gap loss principle is one common principle. To the modal distribution, Attenuators using this principle are sensitive ahead of the attenuator. Thus, they should be near or at the transmitting end or utilized. If not, then intended, the attenuators could establish less loss. By attenuators that use absorptive or reflective principles, this problem is avoided. Basic three types of optical attenuator are there: the continuously variable attenuator, step-wise attenuator, and the fixed attenuator. By specific amount, Fixed attenuators reduce light signals with no or negligible reflection. Fixed attenuators are known for more accurate data transmission because signal reflection is not an issue. The voltage standing wave ratio, range, flatness over a particular frequency, peak and average power-handling capability, attenuation amount, size, performance over a particular temperature, and height are included in crucial elements associated with fixed attenuators. To enhance interstage matching in an electronic circuit, fixed attenuators are also often used.
