Unwetter Update 16: Interview mit Technik-Chef Walter Goldenits (with English subtitles) - YouTube

It won’t be long before there are detached houses on this site.

And what does a detached house like this need?

Fiber optics, of course.

Ideally immediately upon moving in.

That’s why we are already here on the construction site and today we’re going to show you an example

of how we supply a housing development like this with fiber optics.

And we’ll also tell you what this G-Box does.

We’ll even open it up.

Tim is with me today. He’ll guide us around the construction site.

Tim, what is the importance of housing developments for us?

At Telekom, we are involved in the development of around 2,000 housing developments with about 170,000 households each year and connect these to the fiber optic network.

There’s not even a single house here yet.

Why are we already on site?

Well, with this construction method, we have to begin even before the house is built, quite simply

to improve the customer experience at this point.

This construction method allows the entire telecommunications line to be connected before the move-in date, before construction of the customer’s house begins.

In this way, we can ensure that the whole thing can be ordered before the customer arrives.

The customer basically buys the connection along with the house.

Tim, how should I envisage that?

This here is my property and you have excavated a pit.

And here I can already see there’s a fiber-optic cable.

What happens next?

The first step would be to prepare the fiber-optic link.

Here we can see a 7 millimeter speednet pipe supplying the building.

This is blown in from the distribution cabinet.

The advantage here is that we can blow in several cables at the same time.

As soon as that is completed, the next step is to assemble the box.

So, the fiber-optic cable comes out here?

Exactly. Using a compressor, the fiber-optic cable is blown in, is visible here, and is then ready for installation.

And the cable is then connected in the G-box?

Exactly. Within the box, we are prepared with a fiber-optic local loop.

The fibers can be placed here and welded.

Tim, you said we can blow the fiber optics into several properties at the same time.

What makes this solution so special?

Exactly, well the special thing in this case is that we don’t have to make individual appointments with customers,

simply because there aren’t any customers there yet – the properties are vacant.

We can set up the blow-in machine once and plan every property

from the set-up point and from the distribution cabinet, without losing time and

without having to come back on the next day to start again.

How many houses do we have here in this housing development?

We are supplying 20 houses here.

And they’re all being blown in at the same time?

They’ll be blown in one after the other.

So, one house after the other.

This means that, if everything goes smoothly, in these conditions, we should be finished within a day.

Ok, we’re going to take a look at that, aren’t we?

Yes, we’ll take a look.

So, this is the fiber-optic distribution cabinet.

The fiber optics are blown in from here, in the direction of the property.

Exactly. I can explain the set-up here briefly.

Here, behind me, we can see a roll of mini-cables, which are fed through the blowing in device.

At the front, you can see the company’s installation car.

There’s a compressor in it.

When this is switched on, the pressure can be controlled via this control panel down here in blue.

The cable is inserted and, using compressed air, is blown through the speednet pipe as far as the property.

Our colleague here is now already getting the fiber-optic cable ready.

So that means splicing is also done here?

Exactly. So, imagine that the main cable comes in here at the distribution cabinet and is then spliced into the branch cable.

So it’s like the connection point between main cable and branch cable.

Here we can see 22 pipes with a diameter of 7 millimeters, and each pipe is intended for one property.

What’s the approach for this kind of new housing development?

What are the first steps you have to run through?

Long before construction begins, we have to speak to the local authority, quite simply to find out

how many plots are involved. Staking out the plots is also a job for the local authority,

and based on this a development plan is generated, which we then discuss together with the local authority, and schedule accordingly.

Well, we can’t see any demarcations here right now, but based on this plan you know where the fiber optics are to be laid?

Exactly. Based on the development plan in combination with the site plan, we know where the plots are,

how big the plots are, and accordingly also where the fiber-optics should be positioned.

Right, and this is the G-box.

Tell me what’s special about it.

What is the benefit for the customer?

Well, this enclosure here is basically the housing that protects against the soil.

Here we have the inlay – we’ve already take it apart in advance.

I’d like to talk a little more about that.

I’ll show it again briefly from the front.

This is pretty much what the customer would see from above, provided with a protective cover.

Inside, there is another inlay with a submersible bell function.

Submersible bell function? Why?

Imagine that the water level in the soil rises after heavy rain.

The water might rise to a level that would flood the interior of the housing.

But this submersible bell function eliminates this problem,

as the water can collect at any position and does not flow to the inside.

Here we can see the inner workings.

This is where the fiber optics are placed or rather the excess lengths are stored.

And at the top here, there are pre-assembled connectors.

And the whole thing is then connected with these connectors here.

So, that means more splicing is required here?

Exactly. So, with this design, we have two places where splicing is necessary.

Once at the distribution cabinet and once in the box itself.

But as the customer I don’t have to do this myself?

That’s right. As a customer, we only have this visible connector outside of the protective piping

and the customer can plug in simply and conveniently.

So the entire housing is already installed here, we can see that.

And before the inlay is inserted, the fiber optics are spliced here.

Is that correct?

That’s right. At this point the fiber optics are spliced and the pre-assembled connectors are inserted.

And then it’s placed in the ground, closed up, and the customer can decide

whether or not to leave it visible or bury it completely.

Well, ultimately the cover has to remain visible.

But the customer can bury the protective piping if they want to.

Now I have another question.

This is a building site, after all, and it’s still not clear if there will be a flower bed there, or stones,

how high the grass will be or if I’m going to lay rolled turf on it.

Does the owner still have any say in this, or is it all set in stone now?

Well, the owner of course still has a say.

The civil engineering firm will integrate everything leveled in such a way that we are level with the curb.

If the customer now decides, however, to install thick paving slabs, for example, or to lay turf,

we can adapt infinitely variably within a range of 200 millimeters and ensure alignment with the corresponding ground level.

Fantastic. Is there also an app that I can use to control it?

Unfortunately not yet, but we are working on it.

And when it’s all sealed in – the cable is still here because it still has to be fed in and then the inlay has to be inserted –

then only this pipe is visible at this point. Is there anything else on it or what comes out of it?

The customer will be able to see the connection cable provided with a connector

and at the other side, the customer is supplied with

a so-called owner’s kit/fiber-optic quick-start kit, with a pre-assembled fiber-optic local loop and the pre-assembled connector.

So I simply have to connect it all together and the connection will work.

And then I roll the cable out as far as the wall of my house?

That’s right. Usually there should be a multi-branch connection box or we will provide a wall duct, if the customer wishes.

So then, the customer has to carry the connector from inside the house to the outside, fit the fiber-optic local loop on the wall, and connect at the connection point here.

And that’s where I can connect my router.

Exactly, that’s the fiber-optic input directly for the router.

So, as soon as I go through my house door for the first time, I pull the cable, connect it to the wall here and plug in my router.

That’s right. And theoretically, you could be surfing already just one day later.

Sounds good! I wish you good luck for the project.

Thank you.
