A team of specialist submarine cable experts will arrive in Raglan this month to lay the first section of the Tasman Global Access (TGA) undersea cable.

 

Telecommunications companies Spark, Vodafone and Telstra are investing approximately US$70 million to build the TGA cable, which will significantly improve New Zealand’s international broadband connectivity.

 

Other benefits of the new cable include strengthened links into fast-growing Asian markets, important redundancy and resiliency, and better connection with the five main international cable systems currently serving Australia.

 

The consortium of Spark, Vodafone and Telstra have contracted Alcatel-Lucent Submarine Networks (ASN), now part of Nokia, to lay the first cable between Ngarunui Beach at Raglan and Narrabeen Beach in Australia.

 

 

Spark’s General Manager Wholesale and International, Lindsay Cowley, and Vodafone’s Wholesale Director, Steve Rieger, jointly commented on behalf of the consortium:

 

“The work in Raglan marks an exciting and important milestone on the journey to having the TGA cable ready to start carrying data across the Tasman towards the end of 2016.

“The first stage will see the crew of the MV Tranquil Image - a specially fitted out New Zealand vessel - bury a three kilometre stretch of fibre optic cable from Ngarunui Beach, through the surf zone and into the ocean.

 

“Once the Raglan shore landing works are complete, a larger specialised ASN ship will arrive in New Zealand to connect the next section of cable, taking it across the Tasman and eventually connecting it to the Narrabeen Beach landing in Australia.”

 

The cable laying activities at Ngarunui Beach are scheduled to commence on 29 March and this first stage will take approximately one week to complete.
The consortium cautions that weather conditions may impact the schedule:

 

“The goal is to complete this first stage as quickly and seamlessly as possible, however the health and safety of the crew, and the public, are our first priority.

 

“We are keeping the Raglan community informed of the key construction dates and activities and we are extremely grateful for their understanding and support of the project so far,” said Lindsay Cowley and Steve Rieger.

 

The TGA cable is currently on track to be completed, tested and ready for service by the end of 2016.The 2,300km length of cable is comprised of two fibre pairs, and will have a total capacity of 20 terabits per second.

Only if it's being done by one the UFB Contractors, but don't worry they will claim its is UV stabilsed and waterproof :)

Be nice to see direct to Sydney cables from Wellington and/or Christchurch to reduce latency in the rest of the country.

Yes, my thought was that as they all come into Auckland, even with several cables it leaves the whole country with a single point of failure? Mt Ruhapeu goes boom and the whole country becomes a Local Lan? 🤔

given there is likely multiple routes for traffic from Auckland south thats irrelevant, given about half the country is in auckland, and probably a lot of the ISP's infrastructure is there as well.

 

One cable comes in to the east coast, the other 2 come in the west

When I saw that work was starting on the new TGA cable I first thought that it was a Tauranga cable   until I read on..

The gateway out of NZ is there, which I assume is specialised infrastructure, so it does make sense.

But Coast to Coast is 16kms and "Nz gateway is out of there" again leaves me thinking "single point of failure-no OFFSITE (distant) backup=bad plan?

And it looks like things are happening: http://www.niwa.co.nz/our-science/coasts/tools-and-resources/cam-era/raglan-a

 

This look a lot like the MV Tranquil Image mentioned in the original story, off Ngarunui Beach.

What's the Tasman 2 cable marked on the map in the first post?

 

I thought there was just the Southern cross cable out to Australia at the moment?

I believe that Tasman 2 is only for voice.

I wonder how far down they put that cable. Probably a few metres or so.
