Fibra Partilhada[ Nos/Vodafone]

Boa tarde,

Agradecemos a sua mensagem @SemFibra.

Em alternativa à sugestão do @Guimas recomendamos o teste de cobertura através do Site NOS.

Obrigado

Boa tarde. Entrei no teste de cobertura da NOs para verificar se na área há fibra e diz que sim há. Só que ao ligar para serviço ao cliente, falam que há fibra híbrida, no meu contrato aparece "Tipo de serviço: Fibra", por tanto estou a ser enganado por NOS, já sou cliente a mais de 2 anos e desde que instalaron meu serviço, foi feito com cabo coaxial, qualquer pessoa com conhecimentos básicos sabe que o cabo de fibra é diferente ao cabo coaxial. 

Tendrei que ir novamente ao livro de reclamações para resolver este assunto?

É HFC, considerado fibra na mesma.

Não senhor, você está a misturar maçãs com peras. HFC nao e FTTH.

Pode ler o seguinte, não sou burro, conheço pouco da matéria por isso NOS está a enganar às pessoas oferecendo fibra híbrida quando deveria ser fibra ótica até a caixa de ligação para o modem.

"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, or wireless connections. As a result, FTTH networks have greater capacity and significant functional benefits over HFC networks. However, HFC can scale in capacity, both through expansion of fiber and upgrading of electronics, and HFC provides a logical evolution path for the hundreds of millions of homes and businesses connected by the technology to gradually reach gigabit speeds.

Because of the properties of fiber optics and the capabilities and scalability of fiber optic electronics, FTTH provides many capabilities that HFC cannot provide. Among current communications technologies, only fiber has the “off-the-shelf” capacity to support gigabit and higher speeds to the majority of users on a network. FTTH is also the only technology with the option of high-speed symmetrical services. At the root of the difference is the superior physical capacity of a fiber optic strand, as compared with coaxial cable.

As an example, inexpensive, off-the-shelf equipment used by Google Fiber and other providers can provide symmetrical 1 Gbps service. This is not feasible on an HFC system unless fiber has been extended almost all the way to the subscriber—and even then the service will not be symmetrical. A 1 Gbps cable service will not be a reality until DOCSIS 3.1 is introduced over the next few years, by which time the FTTH state of the art will be 10 Gbps or faster. Therefore, in any ‘greenfield’ setting, or where a telecommunications operator is not leveraging substantial legacy infrastructure, FTTH is the logical choice for a new wired broadband network.

With the cable lengths and components in a typical cable system, coaxial cable is limited to approximately 1 GHz of physical capacity (spectrum), and operators allocate this capacity with roughly 20 times as much downstream (network to user) as upstream (user to network). An additional limitation arises from the shared nature of cable modem service. Because bandwidth within a neighborhood is shared rather than dedicated, speeds may be significantly decreased by one’s neighbors’ simultaneous use of their cable modems."

@CRISTIAN LOPEZ, o serviço Fibra subdivide-se pelas suas modalidades FTTH e HFC, no entanto, não por esta diferenciação o serviço deixa de ter a nomenclatura de Fibra. 

Obrigado
