Southern Cross Cable Network says it has successfully implemented Cienaís 100G transmission equipment across its network.†Sales and marketing director Ross Pfeffer says the move increases capacity to 2.6Tbps on the two cables and increases the total capacity between Australia, New Zealand and the USA to 12Tbps.
Telecommunications experts, including former Telecom NZ CTO Murray Milner, have previously suggested New Zealand will need additional submarine capacity within a decade. Advances in submarine cable technology and gradual switch in demand from the USA to Asian online destinations suggest capacity is not the main issue for cable users.
Is Southern Cross enough?
What keeps senior ISP and telco engineers awake at night is that, at present, they have to rely on a single monopoly provider and what could be seen as a single point of failure. That last point is overstated, as†Southern Cross operates two cables, which means thereís a degree of redundancy.
But two lines still leaves telcos and New Zealandís growing digital economy relatively vulnerable. This explains why thereís a groundswell of industry support for rival cable projects.
Telecom NZ, Vodafone and Telstra planned Tasman Global Access looks set to add capacity between Auckland and the East Coast of Australia. Some in the industry fret that Telecom NZís stake in TGA and its half ownership of Southern Cross amounts to new monopoly.
Hardly a co-incidence
Itís almost a year since the last press release from Southern Cross. The latest†announcement comes just one day after would-be submarine cable rival†Hawaiki Cable announced plans†to land its trans-Pacific cable in Whangarei.
As others have noticed, that canít be a co-incidence.
