Just received:

 

...With 144 individual fibre strands the new cable significantly increases the Internet and data capacity to the Island, while providing a diverse route and improved resilience for the Island’s residents...

 

 

 

So how is the new Waiheke network being designed that requires 144 strands?   Even Southern Cross only has 6 fibres.

SxC also have massively expensive DWDM tech to achieve what they do, would be hard to justify that for a couple of thousand residential customers.

 

Tech used by Chorus would be 40G or 100G links each using two fibre cores, so plenty of capacity into the future with 144 cores. Also the cost of cores is nothing compared to the overal cost of pulling a cable in, so 144 is probably way more than they need for a long long time, but it makes sense in an overall project.

And allows other technology such as Sky or ISPs to be used on different pairs should that be required rather than deploying a full OTN node on the island.

144 is just a standard count for a fibre cable - not that they will use anywhere near that many fibres.

They didn't come on-site but we had an ongoing and fairly detailed email exchange with photos/maps/diagrams. I was hoping for a site visit. I know that they "asked the Local Planner to provide a high level design and estimate" as part of the process.

 

 

Talk to your provider and see if they can arrange a site visit then - but the outcome may not be much different.

Not that it matters but a lot of fibre connections use a single fibre, only some use a pair and often only because there are plenty of fibres available. The normal fibre to the home connection is a single fibre with a second fibre reserved for that address for future services when possible.

 

 

 

144 is a standard cable size, when you are talking about running a new cable across the sea it makes sense to put a decent size cable in to cover any future requirements. And this is a short enough run that they can do that easily enough without much additional cost.
