Fibre Cabling

This type of duct was recently installed to serve a small hamlet in Sussex, see photo:

Can anyone point me to a site that describes the various fibre cables that BT uses and, if not, any information on this one and the 6 - 8mm(?) overhead stuff would be welcome. As for instance, what is the maximum number of fibres per cable, bandwidth, how many million simultaneous HDTV programmes can our 18 house hamlet view or phonecalls make (OK, that last not serious!) & so on?

It would depend on how many million immigrants you allowed in to watch the programmes,

In theory 18 homes could be served by one single fibre with a single splitter and GPON, so you would be sharing 2.5 Gbps of capacity over the fibre, with the bottle being much worse in the ISP network and general Internet.

Each of those mini tubes can carry a bundle of fibres so capacity in the access network is not likely to be a major issue. http://blog.thinkbroadband.com has some items not the kit that Openreach is deploying and some more pictures should appear this week

Very useful. :-[[

What does the chain of symbols represent?

As for your comment, that is something in your mind. Not in mine.

It is indeed a humorous reference to the immigration debate, and what the Eurintors and Brexiteers are both saying, with neither being anywhere near truthful or honest.

I suggest you lighten up, and have the chuckle intended by the post. As a response to a question about millions of simultaneous downloads I consider it reasonable. How do you suggest these millions of streams will occur?

Much obliged.

A few more questions if you can bear it:

What is the diameter of an optical fibre � including all coatings?

How many fibres can be included/blown in small diameter overhead cable (6-8mm? Unfortunately it is out of reach so have not measured it)?

Our hamlet has three of its poles with a manifold and PCP on each. Will OR split one fibre or take a separate fibre to each?

Does OR usually include any redundant/dark fibre in this sort of location?

How many fibres can be included/blown in small diameter overhead cable (6-8mm? Unfortunately it is out of reach so have not measured it)?

What is the diameter of an optical fibre � including all coatings?

In the above scenario around 3mm

Everyone always puts in spare fibres.

The manifold will serve 8 to 12 premises, with a fibre splitter serving a number of manifolds prior to that i.e. this is a GPON roll-out rather than point to point fibre.

Dark fibre is only possible when a point to point fibre scenario, so if looking to do 100 Gbps from one premise to another using a low cost rental from Openreach then not possible.

The manifold will serve 8 to 12 premises, with a fibre splitter serving a number of manifolds prior to that

The manifold, (always twelve ports on those I have worked on) provides BFT back to the DP node and from there fibres back to the splitter.

What's BFT please? The nearest I can find is BeamForming Techniques.

Blown Fibre Tube(ing)

Thanks all.

D'oh!

I'll take the comment as being intended that way although it's probably not overly wise in a charged environment with so much made up arguments out there on this debate.

As I suspect you know, it's the old way of representing extreme disappointment.

No dear, you posted an unnecessary, unhelpful, unfunny and completely off topic xenophobic remark.

It is indeed a humorous reference to the immigration debate...

This is a technical area of debate and your contribution was neither relative nor technical. What if the OP was a recent immigrant?

I'm currently taking some pretty heavy medication that can cause extreme confusion but if you believe the above quote from yourself, then you either have a very warped sense of humour or a far more far out drug regime than I'm currently undergoing.

The mere mention of immigrants is NOT xenophobia. As it happens, the term millions seems to be about right too

In reference to www.express.co.uk/news/uk/672563/Turkey-EU-Britain-exclusive-poll-c...:

12 MILLION Turks say they�ll come to the UK once EU deal is signed

MORE than 12 million Turkish citizens are planning to move to Britain when the country joins the European Union, an explosive poll for Express.co.uk has revealed.

I for one thought your reply was funny mate.

I only saw a newspaper headline, literally in passing a person who was carrying it. (This was after my post in question). Isn't the figure 2 million, not 12?

Thanks . The complainer has just made one valid point however, which I'm about to reply to.

Are you serious? Do you expect anyone to believe a Daily Express poll on immigration... Particularly one supposedly taken in Turkey?

Anyway, as previously stated, this thread is not the place for this discussion.

No, I did not know what that chain of characters meant. I do not lie when posting - thank you for the slur.

It was clear that your post was one of censure, but that is irrelevant to them. I assumed it was supposed to give some weird emoticon on an operating system or browser I've never come across. I didn't consider it worth spending time investigating.

What if the OP was a recent immigrant?

A valid thought which hadn't occurred to me, I'll accept that. But low probability.

More possibly a reader may be. In either case I would expect them to have understood the true intent. Immigration is a predominant feature in the media and has been literally for years. Non-hyperbolically, unlike the "millions" in the OP. My quip arose from the sometimes-made suggestion that people could volunteer to take some.

Your medication may explain your lack of clarity of thought. I do not appreciate the suggestion that I may be taking mind-altering drugs. (Now what was that string of symbols again ...? )

Well you started it

Thanks Seb. Point accepted.

Immediately after my post to BatBoy so not having seen this post of yours I did send a PM to the OP apologising if I had given any offence, and including something highly relevant to the advice being given in the thread. (00:07:09, which I'm happy for you or Andrew to read). (Note to others who don't know, site policy is that staff and mods do not routinely read PMs).

Unfortunately I also made my lengthy reply a few minutes ago to the complainer before seeing your post.

Quite. PM sent, which is what I suggest you should have done in view of what you now say.

I sent you a PM just after midnight that you haven't picked up. In case you haven't come across them before on this forum, there will be a flashing red icon in the left of the top menu.

Maybe you lack the correct punctuation to indicate your meaning. Listen to:
