fibre optic and copper

hi
fibre optic cable
copper cable
not the same anyone????????????
virgin say are??????????????????
cheers

 

Who is virgin?

 

He meant Virgin Media - UK ISP. Please explaing yourself as it doesnt make sense what you've just said. thanks

 

I was just trying to know if it was a joke.

The answer is no, fiber is "fiber", and copper is "copper", two very different mediums.

Fiber carry light wavelengths, and copper carries electrical signals.

 

There are virgins all around my estate, but they said i cannot get it! as i have copper, not fiber

 

That means you'll have to stick with good old (or bad) ADSL Oh well,
Maybe "up to 8meg" will make you feel better

 

ok
virgin media say that you get fibreoptic broadband but the cable in my house is a copper cable?
rang they say that it is the same?

 

maybe they mean your copper cable is connected to their optical outside of your house?

So it`s short length means it is capable of faster speeds.

 

well what happens is, you get the coax cable right? its a copper cable as you know then it goes into one of those green cabs outside your house or w/e and then it takes its way to an UBR (universal broadband router) somewhere in your area via FIBER

 

so if the cable in the house is copper the fibre optic cable is the same but ntl put the cable down my street
can a fibre optic cable be sent down a copper cable?

 

so you can get fibre optic
but not to the modem

 

ntl:telewest layed its fiber in the 80s, its preaty much everywhere now. one of those will be somewhere underground in your area connected to a cab outside your house or in nearby neighbourhood. then you'll have a coax cable wich is basicaly copper going to your house (its cheaper that way, however is still fast, much faster than PSTN copper lines).

Coax Cable from your house goes straight into Green Cab where its connected to a media converter which then connects to nice speedy fiber. Dont warry about the speed as coax is capable of 1Gbps or even more (over short distances).

Ntl:Telewest are now testing 100Meg in some areas of London which obviously wont be available to us yet. So its all looking good

 

What do you mean?

You will get a cable modem.

 

Why not run fiber in your house?

 

1. Fiber comes to the ONT (Outdoor Network Terminal) outside your home. Then from there it will use cat5 cable (which is copper wires) to connect into your router.

2. In other designs, fiber comes to the curb (common box for the community) and from there goes into your house using DSL, so using conditioned telephone copper twisted pair. In this scenario, you will not get the same throughput than case 1, much less.

 

Well in UK instead of cat5 we use coax cable which uses copper connects to the cable modem.

 

It would be too expensive to lay fiber to every single house and then install a media converter which doesnt come cheap.

 

@applx: When dealing with fiber the modem is not external, it is in the ONT, so the interface to the router is cat5. Are you saying that in your place the modem is not integrated with the ONT?

 

I didnt say it would be cheap, but you could run it from your curb to your house to your router. Not like it would provide any faster throughput than a coax cable or cat5e cable though.

The only real place you would need fiber is from the isp to your curb or near your house at least. The small distance coax cable would travel from there to your house would be small enough that it would not limit the speed.

 

It would, read my post, the 2nd method is used in Montreal and although they promise 15Mbps DL, but they only reach 6Mbps, their excuse is it depends how far you are from the box.

 

In UK, the fiber would come from an ISP to their UBR (universal broadband router which would be placed in an exchange or locked up somewhere in the street). Then a coax or a fiber cable would run down the street where its connected to a cab (a green box with lots of wires, thats where end users are connected to). Then another coax will run straight to your house. We dont use Cat5 though.

 

Well Cost is the reason really. Dont forget that you will need to install a media converter on the end of that Fiber cable to transform light signals into digital signal as well as the router on the end of that. That would cost quite a bit for an ISP to provide this sort of services, dont you think?

They do user "your" method tho for their business clients (dedicated/leased lines). It doesnt come cheap tho

 

That's interesting, so your router's interface is coax, cool. so why is the other guy saying that is cooper?

 

Not the router but the modem has a coax interface which is then transformed into standard R45 connector.

I've got no clue what the other guy is on about? Maybe because coax has a copper core wire? No idea. I wouldnt be complaining as its very fast.

Where you from WifiMan?

 

Well, the coax inner conductor is copper definitely, and the r45 or RJ45 is the jack where the cat5 cable connects, same thing, and cat5 is certainly made of twisted copper wires.

I think the confusion of the OP comes from the fact that he probably expect that the fiber service is fiber all the way into his laptop , but as we all know is not the case.

 

Well technicaly it is fiber -_-
Id be happy with it, just cant get around with getting a contract, i've got a disscount with them Guess ill just stick with DSL for now which is also fiber (from ISP to the local exchange)

 

If is not fiber from the ISP to your home then is not fiber technology, you won't get the high throughput, if from the LE to your house is DSL, then it will depends how far you are from the DSL box, farther, lower throughput.

Here in the US, ISP fiber means fiber to the home. Which is more honest to say, because the backhaul has been fiber for decades already, the last mile technology is what it really counts. Like in Montreal (Canada) they advertise fiber but it's not true, the backhaul is fiber but is really DSL to the house, how do I know this? because the modem is a "DSL" modem

 

in the UK there is only 1 company that offers fiber and its Virgin Media (also know as NTL:telewest) and what they do say is : get high speed fiber optic broadband, well its what you get though via coax to you house. Unlike DSL copper pair, coax is much more capable of higher speeds. Its only Coax for 100meters down the road then they use fiber.

 

Very interesting indeed. What happened to power line's internet? It was very big in UK some years ago.

 

lol i dont think they went through with the idea never even heard of it in the UK One question tho. How come your always on? i've been at work posting those comments and now im back home and your still on here is this your job? lol

 

I'm a consultant, so my computer is always on indeed, so I multitask between projects and this forum. I just need to be careful not to get too much sucked in so I don't neglect my own job But certainly my time is more flexible than others, and since I like to help people this forum is good for that.

 

Therein lies the hard part - this place can become addictive.

 

hi
ok the box on the top of my road was ntls and you are saying that the box will have fiber cable in it?
ok we had someone down the street today have cable in and the box was open so i ask the cable man and its all copper in the box?????????????

 

No, you said that, you said that you bought fiber service. But you said that you have copper wires coming into the house, so I said they may come close to your house to a center with fiber and then they come to your house with DSL, that's what I said.

I also said that here in the US we come with fiber to the house, and that from there we get into the house to connect with the WLAN side of the router with copper/cat5 copper cable, which is not the DSL telephone copper twisted pair.
