Spark, Vodafone and Telstra today confirmed a less ambitious plan to lay a separate subsea communications cable between Raglan and Sydney at a cost of US$70 million, which the companies said would make New Zealand’s international connections more varied and secure.
The three companies said they would start construction of the 2300 kilometre Tasman Global Access cable early next year and expected to complete it by the middle of 2016.
French multinational Alcatel-Lucent has been awarded the contract to lay the cable, which will comprise two pairs of optical-fibre with a total capacity of 20 terabits per second.
That’s a lot. By comparison Southern Cross has capacity of around 12 Tb/s (of which around 3.6 are lit).
20 Tb/s would allow one million users to be pulling 20 Mb/s each.
Good to see some increased competition in the cable area.
