Abstract
There is a constant growth in the demand of data information transmission capacity, that is, more and more people send data, voice, video signals, among others, through communications networks. Due to the above there is great interest in improving network devices, such as optical amplifiers, which must cover a large bandwidth and generate greater gain than those currently available. For this reason in this work a computational simulation for a Quasi-system was carried out three energy levels of Erbium and Ytterbium varying their concentrations and proving that they are optimal candidates in a zinc phosphate matrix as this type of glass contains properties such as, high transparency, low melting point, high thermal stability, high gain density due to high solubility, low refractive index and low dispersion, which makes them optimal as signal amplifiers. The results confirm that by increasing the doping of the Erbium ion the gain of the amplifier decreases, contrary to the Ytterbium ion that by increasing the doping the gain of the amplifier increases.

This allows the manufacture of various devices with high energy gain. This type of glass contains properties such as, high transparency, low melting point, high thermal stability, high gain density which is due to high solubility, low refractive index and low dispersion [2]
Summary
This allows the manufacture of various devices with high energy gain. This type of glass contains properties such as, high transparency, low melting point, high thermal stability, high gain density which is due to high solubility, low refractive index and low dispersion [2]. When the distances covered are tens or even hundreds of kilometers, it is necessary to amplify the signal
