Hi team

I’m in chch and want to upgrade to fibre. When our house was built telecom/sparky laided green conduit to the side wall of the house at the same time I had a second conduit laid by the sparky with sweeping bends and ran this to where the outside edge of our to be laid concrete would end. The assumption I made was get some conduit under the concrete so that fibre could be run into the same entry point as telecom and no concrete would need to be cut . In the wall I had micro duct run back to a network cabinet .. Seemed logical. Fibre has now been laid down out street and we have a point about 7 meters away from our house down the fence line. Last weekend I dug a channel for enable to be able to put some conduit in the ground . I exposed the end of the 25mm conduit I had laid under the conference so they could connect to it. This week enable arrived . They came with what looked like red conduit like the stuff sticking out of the ground fairly stiff stuff , apparently they tried to pass this through the 25mm conduit I had laid and failed and decided to leave saying maybe the bends were too sharp. They left the red stuff for me to lay if I wanted to try.

My question.

I thought they would lay 25mm solid conduit to the demarc point at the front of the house and connect that to the 25mm conduit I laid.. Then pass athinner lighter more flexible micro duct along the inside of it. Is it normal for the more solid red tubing to be passed down 25mm conduit?

Anyone got any pictures of what they normally do? I’ve seen installs along fence lines where they used a thinner conduit, sometimes black. Was my technician confused or lazy?

Help please

Yes, the red stuff is normal for them to run and it's really tough to bend.

Are you sure that the sparky used sweeping bends and not elbows?

Can you get a snake down the duct and tie on a strap/string?

If you don't have access to a snake can you use a vacuum and a plastic bag to suck a string through?

I did have a cat 6 cable in there but that was removed. I’ll try and get it though this weekend with a snake etc . Yes it’s large bends . I witnessed it when laid. large green bends . The largest telecom green bends you could buy from ideal or redpaths

try to get the snake through and then some of that blue builders strapping as you can tape that on really well around the red tube and you should be able to pull that through easy enough then.

Soak the red condiut in some hot water and that will help.it bend as well. Thats what i have done with the red condiut, othweise ask for the black microduct they attach to fences as that will be easier to pull through your condiut.

Would you know if the black stuff needs to be run inside 25mm conduit our canit just be buried.

Also when running the micro duct internal (white empty tube ) how much needs to hang outside the external wall? Sparky has cut off most of the excess so there is only a few cm hanging out . Interested to know what is required

black ruggerdised microduct can just be buried but nothing to stop you running it inside conduit

The micro duct is easily joined and extended using compression fittings, so as long as there is a couple of inches it should be fine, but does depend where it goes to next.

This duct sounds like it is the low smoke tube that is used inside the property from the ONT to the ETP, and I'm not sure if it can be buried directly.

Microduct has 2 layers of plastic, the first usually being black and then the inner being either green or red pending on the provider.

The micro duct also usually has a trace wire in the duct between the black sheet and the green sheath.

Hi, I dont think he was expecting the white indoor tube to be buried. The bit hanging out of the exterior wall that the sparkie has cut short I presume is to fit into the back of the ETP, so only a couple of cm is probably required, but ideally a bit more than that is left for the installer to workout how much he needs.

my bad just re-read that, that few cm may be fine, i would see if there is any play in the tube you might be able to get the extra inch or 2 if it has been pushed back in the wall or loosely sitting there

Hi Guys

Thanks for all the information

I can see the sparky has used the top microduct ( no fibre ) and run that from the on wall network box to the outside wall of the house. it runs inside a 20MM flexible conduit across the garage roof etc.

Any issues with the fact its the non fibre filled version or will I need to change that?

Looking at the out side of the house

I have the white micro duct poking out about 1 - 2cm I'm sure there is some slack, and it pokes out a lot more in the network cabinet so I'm sure it could be pulled thorugh a little, but my stupid question. the white tube come out the wall at 90deg, it then would need to bend DOWN to meet the conduit that comes out of the ground, just concerned that's a sharp bend?

Has anyone got any pictures of how the connection on the wall inside the wall box looks?

I'll contact enable today and see if I can get some black microduct to go in the conduit I have.

Thanks

Hi you are fine the empty tube will get filled with 2core by the installer when he does his bit.

As for the etp it will be used as a fibre spoolling cassette area and contain the splice , the situation you have with it poking out at 90deg is normal and fine.

Further to this

I rang Enable to ask about the Black micro duct vs the thicker red. And the option to extend the solid 25mm conduit i had laid down to the property boundry.

Unfortunately they were not very helpful on this call, they will not supply the black microduct to me, and they also dont seem to want to run any 25MM solid conduit.

They have told me i need to do a site visit to create a plan. I know the plan, its to get conduit and micro duct into the trench so that im prepared for future.

So next round of questions.

Assuming i cant get the red stuff through the existing conduit and i cant seem to get them to provide me the black thinner stuff.

1. If i extend my solid conduit to the property boundry, is there a requirement for any particular colour? White, Red, Green etc?

2. Should i put a draw line down the length of the conduit ( was thinking 10M of left over cat 6 i have ).

3. Should enable really be providing me the black stuff?

4. Should enable be laying the 25MM solid rather than the red flexible?

Just want know what approach i should take as i want to get the trench filled in this weekend

Thanks

I just used white 25mm conduit.

Yes That can work if you cant pull the red microduct through

3. Should enable really be providing me the black stuff?

When you have a scope done, they will see the conduit in the ground and the team who does the external build will feed the microduct through (they will have black mircoduct with them) so not to worry too much as long as there is a draw wire in the conduit if you cant get the red microduct through - as per my earlier post, I soaked one end in hot water to make it more flexible and once it had passed the 25mm sweeping bend, I could pull the rest of the red microduct through.

4. Should enable be laying the 25MM solid rather than the red flexible?

- No as the red microduct is tough and is ready for the fibre to be blown where as conduit it not ready for fibre to be blown down it.

Just want know what approach i should take as i want to get the trench filled in this weekend

Thanks

See above for my responses.
