La solution GPON<\/strong> est id\u00e9ale pour distribuer des services IP m\u00eame dans les grandes installations telles que les villages et les centres de vacances car elle permet des tron\u00e7ons allant jusqu’\u00e0 20 kilom\u00e8tres<\/strong>.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Tous les services jusqu’\u00e0 20 kilom\u00e8tres<\/h2><\/div><\/div><\/div>

L’une des particularit\u00e9s de la solution fibre optique passive GPON<\/strong> consiste en la possibilit\u00e9 de r\u00e9aliser la distribution de services sur de tr\u00e8s longues distances<\/strong>.<\/p>\n

Gr\u00e2ce \u00e0 l’utilisation de la fibre monomode et \u00e0 la puissance du signal optique transmis par l\u2019\u00e9quipement OLT (Optical Line Terminal), en effet, par rapport aux 90 m\u00e8tres de c\u00e2blage traditionnel en cuivre, la solution GPON permet de cr\u00e9er des connexions jusqu’\u00e0 une distance de 20 kilom\u00e8tres<\/strong> entre le point d’\u00e9mission OLT et le point de r\u00e9ception ONT.<\/p>\n

Le syst\u00e8me est donc \u00e9galement id\u00e9al dans les tr\u00e8s grandes installations, telles que les villages et les campings<\/strong>, ou dans les zones industrielles<\/strong> pour la cr\u00e9ation de syst\u00e8mes de vid\u00e9osurveillance p\u00e9rim\u00e9triques; l’avantage est \u00e9galement important vis-\u00e0-vis d’\u00e9ventuelles contraintes architecturales ou paysag\u00e8res, car la fibre optique s’installe facilement m\u00eame dans les gaines les plus \u00e9troites.<\/p>\n<\/div><\/div><\/div>

Des syst\u00e8mes extr\u00eamement fiables<\/h2><\/div>

La possibilit\u00e0 di gestire lunghe tratte di distribuzione rende il sistema GPON adatto anche alla realizzazione di impianti ad alta affidabilit\u00e0<\/strong>, dove vengono richiesti elevati standard di sicurezza<\/strong>; si tratta di sistemi che prevedono una ridondanza passiva e attiva<\/strong>, realizzati con distribuzione ad anello<\/strong> che parte dalla sala server e vi ritorna, collegata a due diverse porte della macchina OLT.
In questo modo, nel caso in cui l\u2019anello venisse interrotto in qualsiasi punto della tratta, automaticamente la macchina OLT, rilevando la mancanza di apparecchi distribuiti in campo, riattiva il tratto dell\u2019anello disconnesso.<\/p>\n

La possibilit\u00e9 de g\u00e9rer de longues sections de distribution rend le syst\u00e8me GPON \u00e9galement adapt\u00e9 \u00e0 la construction de syst\u00e8mes extr\u00eamement fiables<\/strong>, o\u00f9 des normes de s\u00e9curit\u00e9 \u00e9lev\u00e9es<\/strong> sont requises ; ce sont des syst\u00e8mes qui fournissent une redondance passive et active<\/strong>, r\u00e9alis\u00e9s avec une distribution en anneau qui part de la salle des serveurs et y revient, connect\u00e9e \u00e0 deux ports diff\u00e9rents de la machine OLT.
De cette mani\u00e8re, si l’anneau est interrompu en un point quelconque du tron\u00e7on, automatiquement la machine OLT, d\u00e9tectant le manque d’appareils r\u00e9partis sur le terrain, r\u00e9active le tron\u00e7on de l’anneau d\u00e9connect\u00e9.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"parent":154689,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-154701","page","type-page","status-publish","hentry"],"yoast_head":"\nDistance de transmission -
