    Fibre needs to come quick my posts are even taking ages to upload!

    Don't forget that the F in FTTC is Fibre. They've run 24 strands of fibre to each FTTC cab. 4 of them are allocated to VDSL, the remaining 20 will be used to provide for the blue lines (and presumably NBP if they win).

    They've also, presumably, purchased the VDSL gear for the cabs, so they might as well use it for now and get some money from subs.

    So they've run 24 strands of fibre to each VDSL cabinet, regardless of blue-line status? That's very encouraging if so. It almost pains me to say it, but I actually hope Eir win the NBP contract now. Looks like they'll have a head start on all the others if they do anyway.

    Also (and this is for anyone really), I'm not familiar with GPON FTTH, so how many customers would 20 strands typically service?

    Yeah I asked all of this before on here and somebody replied that FTTH will come straight from exchange to the home, it may have been that my question wasn't clear, but the reality is that the fibre is running via the cabinets to peoples home although it's still directly connected back to the exchange.
    This made sense to me after watching the eir videos months ago.
    And it's making sense again now.
    I was let to believe I was wrong and that they would be running new fibre lines from the exchange out to the blue line areas - however it seems to be that most of that is already done(as they have it already at the cabinets). Beginning to think the dates on their website ad up now. :D

    With you on that 100% Dero. It also makes a lot more sense why they continue to focus on cabinets because they all need to be in place along with the spares for FTTH to start properly. Also gives them time to get the exchanges ready. Can't believe I'm actually hoping Eir will win the contract now too.

    Sounds like they may be RSUs, when a business park or airport got an.exchange that was common. I remember one in Mallow being trouble before (very limited bw).

    Basically awkward/troublesome stuff left till last, makes a lot of sense.

    Is this the Mallow AEH Yard you are thinking of?

    How much approximate bandwidth is there per strand?

    Eir are light years ahead of all the rest, even with SIRO's ESB infrastructure.

    Eir have quite a lot done already and by the looks of things will have a significant amount done before the NBP is awarded.

    Maybe it wasn't mallow, certainly the Cork coastline with an industrial unit. Need my laptop to look further.


    78Mb assuming 100% efficiency. A 32 split is a really bad idea with GPON and by the time we see 10GPON OLTs it'll be too little too. If you had 30x 8 streams (among 640 houses which may have 4 STBs each) you're already at a very significant load.

    I'm hoping the average is more like 12-15 per strand. 200 sub cabs support something close to this.

    EDIT: you said strand, I answered user.

    I could have sworn that somebody said that eir were talking about using GPON and only splitting a strand amongst 16 users and even down to 8 users in lower density areas.

    I've been searching for this and I just can't find it, but I definitely remember thinking that this would be perfect in my black hole in the mountains. ;)

    Lots of very rural exchanges in Cork. Wouldn't surprise me if many were 19th centuryesque setups.

    Isnt each premises getting 2 fibres/strands, 1 active and 1 spare

    That's the drop. Strand A is fed back to a splitter(joiner) and shares the rest of its way to exchange and strand B is dark.

    That's exactly what happened here. Digging/manholes started 10 feet away from the last cabinet here and they have been working their way further into the countryside doing ducts/manholes etc.

    Between the exchange and the cabinet has been completely untouched since the VDSL rollout here 2 years ago.

    It doesn't look much different to a telephone cables. There are fibre cables already on poles bringing fibre to the exchange. Sometimes you might not be able to tell the difference

    I thought fiber on poles would look much thinner than normal telephone cable?

    I would think the same too, having seen fibre optic cable before. (in physics class mind you :P)

    Nope, It needs a decent strand of metal wire to reinforce it.

    Just wanted to know because they were putting cable up down the road from me for a couple of days last week and it looks the same as it did before they started. I was expecting if its fiber that it might be orange or green or something other than black.

    I thought telephone poles usually had 2 cables?? So if there's a third cable chances are it's fiber.

    Nah, that's not a good way to tell. You could have any combo on a pole including POTS + CORE, POTS + POTS etc. DPs can be up to 1 in 8 out in avenues and the like.

    Ive worked with single strand fibre for ducts in server rooms, and also ran reinforced fibre which had 8? fibres between server rooms etc many many moons ago...you are talking 10-16sq cable for that...double core unreinforced is like good speaker cable...

    Brand new pole erected this week in Kiltale (Tara exchange), looks like it's been put there to serve a back road (that has a blue line) that connects to two other blue-line roads.

    Here's a photo I took of the core fibre that's run to my village exchange. This is the last pole before it goes UG to the exchange (about 200m away). This is a 48 strand fibre cable:

    Ignore the elements thing. I was explaining to somebody in another thread how fibre can be exposed to the elements.

    anyone know have they started on those blue FTTH lines yet? is it likely to be in place in the next year?

    not sure we can wait another year even, we might just go with the satellite broadband option, guaranteed 10mb afaik.

    our speed has been <1mb for as long as i can remember with constant disconnects, like most in this thread i imagine!

    Have a look at this map: http://fibrerollout.ie/where-and-when/
      Tick the "all" box on the right hand side
      Find your house
      If it's on a blue line trace it back to the exchange.
      It should give an estimated date.

    Hopefully it says something like "Live FTTH Fibre Services with speeds up to 1000Mb/s is Autumn/ Winter 2016"
    Otherwise it'll just say "FTTH 2017-2020" meaning you're in for a bit of a wait.

    thanks. i traced it back to the nearest exchange and it said "exchange is live". i don't think any of those blue lines are installed yet though.

    I noticed OpenEir now have the number of FTTH homes of the exchanges which are part of their 66 towns. E.g. Naas has 2200 homes.

    Does anyone know if it's possible to pull this information from their map with a script of some sort? Rather than hovering over every single exchange :)
