A tecnologia XG-PON1 disponibiliza débitos de 10Gbps downstream, combinados com débitos de 2,5 Gbps upstream. Herdou a formatação da trama e a camada de controlo da GPON, disponibilizando todo o tipo de serviços a maiores débitos e com graus de splitagem superiores. Isto adiciona mais funcionalidades e maiores débitos às redes de acesso ótico, sem […]
V souvislosti s evolucí přístupových sítí se v současné době stále častěji diskutují optické, případně kombinované opticko-metalické přístupové přípojky označované jako FTTx (Fibre to the X), kde optická část přípojek bude založena na některé z variant pasivních optických přístupových sítí (PON), nejčastěji na variantě GPON (Gigabit Passive Optical Network) či EPON (Ethernet Passive Optical Network). […]
Insertion loss tests are primarily used to test FTTx PONs (Passive Optical network) during installation. Insertion loss testing may be performed on individual fiber segments as they’re installed (e.g. test feeder fiber from Central Office (CO) to Fiber Distribution Hub (FDH), test distribution fiber from FDH to AP, or test drop fiber from AP to […]
The following is a list of optical testing tools used for FTTx (Fiber to the x) network: 1. VFL (visual fault locator) is capable continuity check fiber link up to 15km, break/bend visual identifier for fibre along patch panel/hub areas, It is mainly applied in fibre link construction and troubleshooting at locations where fibres are accessible. […]
PON architectures for FTTH deployments are currently based on passive optical splitters to distribute the bandwidth to each customer using fiber splitters providing ratios ranging up to 1:64 or even 1:128. The physical PON FTTH architecture typically supports the Ethernet protocol. PON network feeds a variety of optical network terminations (ONTs) or optical network units […]
Overview A new White Paper by the FTTH Council Market Intelligence Committee finds European FTTH deployment cost estimates are highly accurate. That makes investing in fibre highly attractive. To determine whether the FTTH cost estimates used in European projects accurately represent the actual costs, the FTTH Council approached a wide selection of parties involved in […]
HFC and FTTH networks differ in that HFC extends fiber to a node within a mile of the home or business, while FTTH extends fiber all the way to the home or business—typically terminating the fiber at a customer premises device, which then provides service to devices in the home over copper lines, coaxial cable, […]
In the early days of GPON service providers cared primarily about getting the service to work, and the easiest way to ensure this was to purchase an end-to-end GPON solution from a single vendor, who was responsible to make it work. Providers that used multiple vendors in their network divided their service area into different […]
1. Diseño y consideraciones del proyecto La área urbana tiene las SMEs, o PYMEs, en una avenida principal con 10.000 abonados, de los cuales 8.000 son residencias en MDU. Cada MDU o edificio de departamentos en la área urbana posee 30 unidades habitacionales. Las áreas suburbana cuentan con viviendas unifamiliares (SFUs) y PYMEs, o SMEs. […]
Empecemos con una definición simple; Fibra Hasta El Hogar (FTTH – Fiber To The Home) es la entrega de una señal de comunicación por medio de fibra óptica desde el equipo de conmutación del prestador de servicio hasta la casa o negocio del cliente, por lo tanto es un reemplazo de las redes de infraestructura […]
