# Gaussian Beam

The Gaussian Beam is a beam pattern used to approximate the distribution of energy in a fiber optic cable. It is based on the bell curve, which is a symmetric curve that is widely recognized as a normal distribution of a particular data set. The Gaussian Beam pattern is used to describe the distribution of light energy within the core of a fiber optic cable.

The Gaussian Beam pattern is based on a mathematical model which is used to predict how light energy will spread in a given environment. This model is based on the physical principle of diffraction, which states that the shape of a light beam will be affected by any obstacles or barriers in its path. This is why the Gaussian Beam pattern is often used to describe the emission patterns from surface-emitting LEDs.

The most common application of the Gaussian Beam pattern is in fiber optic cables, where it is used to calculate the amount of light energy that is lost to the environment due to the scattering of light in the fiber core. The Gaussian Beam pattern is used to calculate the number of optical signal losses for a given fiber optic cable, which can then be used to determine the required signal-to-noise ratio for the cable.

Overall, the Gaussian Beam pattern is a useful tool for predicting the distribution of light energy in a fiber optic cable. It is often used to calculate signal losses within a cable, and can also be used to describe the emission patterns from surface-emitting LEDs. By utilizing the Gaussian Beam pattern, engineers and technicians can better understand how light energy is distributed within a cable, and can use this information to optimize the performance of their cables.
