En la fibra ??ptica se est??n probando nuevos materiales o nuevas modulaciones de luz para mejorar la velocidad y capacidad de estas redes. Ahora, una de estas mejoras, que ha sido probada en el espacio, vuelve hoy.<\/p>\n\n\n\n<p>SpaceX recuperar?? hoy la nave de carga Dragon que envi?? a la&nbsp;<strong>Estaci??n Espacial Internacional<\/strong>&nbsp;el pasado 8 de diciembre de 2020, permitiendo recuperar m??s informaci??n que en naves Dragon previas y que ser?? la primera que amerizar?? en la costa de Florida. En ella es donde vendr?? una de las pocas&nbsp;<strong>fibras ??pticas<\/strong>&nbsp;creadas en el espacio.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">ZBLAN: ??ser?? esta la fibra del futuro?<\/h2>\n\n\n\n<p>Esta fibra ??ptica es conocida como??<strong>ZBLAN<\/strong>??por las siglas en ingl??s de los elementos que la forman (<strong>circonio, bario, lantano, sodio y aluminio<\/strong>). Este material est?? formado por un vidrio completo con la ventaja de que tiene unas excelentes capacidades de transmisi??n de ondas de largo alcance, con una menor p??rdida por metro que los cables de silicio que se usan en la actualidad, y permitiendo operar con un rango de longitudes de onda m??s amplio. Gracias a ello, es posible transmitir m??s informaci??n, m??s lejos y a mayor velocidad necesitando menos repetidores, superando los??l??mites de la fibra ??ptica??actual.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.adslzone.net\/app\/uploads-adslzone.net\/2021\/01\/zblan-fibra.jpg\" alt=\"\" class=\"wp-image-830536\"\/><\/figure><\/div>\n\n\n\n<p>Adem??s, las propiedades de ZBLAN en<strong>&nbsp;infrarrojos medios<\/strong>, que va desde las&nbsp;<strong>5 hasta las 25-40 micras<\/strong>, tambi??n son prometedoras para monitorizar el medio ambiente, ya que puede absorben di??xido de carbono y metano.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Fibra del espacio sin imperfecciones<\/h2>\n\n\n\n<p>La relaci??n entre el espacio y esta fibra ZBLAN tiene que ver con que es m??s f??cil crear estos cables en el espacio que en la tierra. Cuando se crea una fibra y ??sta se enfr??a, sufre un proceso de cristalizaci??n que a??ade imperfecciones al vidrio. En el espacio, sin embargo, al estar en un&nbsp;<strong>entorno de microgravedad<\/strong>, los problemas de cristalizaci??n desaparecen y se pueden crear&nbsp;<strong>fibras de vidrio<\/strong>&nbsp;pr??cticamente perfectas.<\/p>\n\n\n\n<p>Por ello, este experimento en la ISS ten??a como objetivo comprobar si tiene sentido crear estas fibras de vidrio en el espacio de manera masiva en el futuro. Aunque esa idea es muy a largo plazo, al menos saben que en el espacio pueden crear fibras mucho mejores que en la Tierra, aunque a un coste mucho mayor. En la siguiente imagen podemos ver la m??quina utilizada y que ha estado meses en el espacio:<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/www.adslzone.net\/app\/uploads-adslzone.net\/2021\/01\/zblan-fibra-maquina.jpg\" alt=\"zblan fibra maquina\" class=\"wp-image-830506\"\/><\/figure><\/div>\n\n\n\n<p>Este no es el primer experimento que ha creado fibra ??ptica en el espacio. La empresa&nbsp;<strong>Made in Space<\/strong>&nbsp;ya hizo pruebas en 2016, creando fibras con menos imperfecciones que ofrec??a una mayor eficiencia en la se??al, y habiendo lanzado ya varias m??quinas al espacio para ir creando diferentes tipos de fibras, las m??s recientes usando los materiales de ZBLAN.<\/p>\n\n\n\n<p>M??s all?? del experimento de la fibra, en la nave Dragon tambi??n vendr??n ratones que han pasado mucho tiempo en el espacio para ver c??mo les afecta estar ah?? arriba. Tambi??n hay otros experimentos relacionados con medicina regenerativa, funcionamiento del coraz??n en el espacio, o bacterias.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Al igual que hay multitud de investigaciones en el campo de las bater??as, en el segmento de la&nbsp;fibra ??ptica&nbsp;hay multitud de ensayos para&nbsp;mejorar la velocidad&nbsp;de las conexiones que usamos a diario.
