“…Losses may occur in connectors, which, usually, have low values; losses also may occur at signal reception due to equipment misalignment, which should be considered in the design to avoid mistakes during installation, or problems caused by wind, blows, or the oscillation of the support structure. For design purposes, we assumed a system loss of 4 dB that represents the sum of such losses, and a considerable value to emulate the worst-case scenario [10].…”

A software pilot application to calculate the parameters involved in subsidiaries interconnection based on FSO technologyDesarrollo de una aplicación piloto de software para calcular los parámetros que involucran la interconexión de sedes basada en la tecnología FSO AbstractFree Space Optics (FSO) technology transmits information using free space optical signals similar to those that travel through optical fibers. The capacity of FSO to connect buildings close together is covered in this paper. Four optical wireless links between three buildings of a fictitious company, considering a building that obstructs the sight line between two of them, are designed here. As part of the design process, several issues such as distance between the equipment, weather conditions, some features of the FSO equipment, and system losses were addressed; moreover, an application that performs the calculations and displays the results of the most important aspects in the design was implemented. The importance of such links is given by their flexibility, low implementation costs, mobility, rapid deployment, high throughput, great bandwidth, reliability, and high security level due to their operating principles, among others; therefore, this type of links are an ideal option to implement a backbone for the proposed network.Keywords: atmospheric attenuation; backbone; FSO technology; geometric attenuation; link margin; optical wireless access; subsidiary interconnection. A software pilot application to calculate the parameters involved in subsidiaries interconnection based on FSO technology ResumenLa Tecnología Free Space Optics (FSO) transmite información por el espacio libre, utilizando señales ópticas similares a las que viajan a través de las fibras ópticas. Las FSO permiten conectar edificios cercanos entre sí, como se aborda en el presente artículo. Se presenta aquí el diseño de cuatro enlaces inalámbricos ópticos entre tres edificaciones de una empresa ficticia, contemplando un edificio que obstaculiza la línea de visión entre dos de ellas; dentro del proceso de diseño se consideraron varios aspectos, como la distancia entre los equipos, las condiciones climáticas, algunas características propias de los equipos de FSO y las pérdidas producidas en el sistema; además, se implementó una aplicación que efectúa dichos cálculos y muestra los resultados de los aspectos más importantes en el diseño; la importancia de este tipo de enlaces radica en su flexibilidad, sus bajos costos de implementación, su movilidad, su rápido despliegue, la alta tasa de transferencia, el gran ancho de banda que maneja, la confiabilidad y el alto índice de seguridad, debido a sus principios de funcionamiento, entre otros, que hacen de ellos una opción ideal para implementar un backbone para la red propuesta.Palabras clave: acceso inalámbrico óptico; atenuación atmosférica; backbone; interconexión de sedes; margen de enlace; tecnología FSO.
