Hace un par de semanas realiz\u00e1bamos un acercamiento a las redes GPON<\/a> y a c\u00f3mo las mismas iban a ayudar a los proveedores de servicio a adecuarse a las directrices de la Agenda Digital Europea.\u00a0Dejamos pendiente por aquel entonces analizar los diferentes escenarios que se pod\u00edan plantear cuando se llevan a cabo dise\u00f1os de red, y en esa materia nos adentraremos en el art\u00edculo de hoy.<\/p>\n

Estoy casi seguro que a muchos de vosotros os sonar\u00e1n las siglas FTTH<\/strong>. Es el abanderado de los operadores de cara a poder presumir delante de sus rivales. El oro de las telecomunicaciones que todos andan buscando. Quien antes tenga en funcionamiento su red FTTH a nivel global se convertir\u00e1 en el operador de referencia para los pr\u00f3ximos a\u00f1os.<\/p>\n

Pues bien, al margen de la redes FTTH existen estructuras de red alternativas basadas en GPON<\/strong> que permitir\u00edan por un lado amortiguar los costes de despliegue y por otro la reutilizaci\u00f3n parcial de infraestructuras existentes (par de cobre, armarios repartidores, terminales de abonado,\u2026)<\/p>\n

El concepto es muy sencillo. Se trata de llevar el punto de interconexi\u00f3n \u00f3ptica a algo m\u00e1s global \u00a0que una vivienda como puede ser un edificio, dando lugar a que se conocen como redes FTTB (Fiber To The Building)<\/strong>. En el art\u00edculo de hoy analizaremos ambas estructuras y las ventajas y desventajas que pueden ofrecer desde el punto de vista de un proveedor de servicios.<\/p>\n

Antes de entrar a analizar las mismas es necesario que recordemos los diferentes elementos que componen una red GPON<\/strong>. Si record\u00e1is b\u00e1sicamente ten\u00edamos cuatro:<\/p>\n
