KANZ 09 (Korea-Australia-New Zealand) Broadband Summit.

By John Nixon 03/11/2009


Tonight I spent a couple of enjoyable hours at the KANZ Welcome Party (Thanks Kordia).
Serious business starts early tomorrow at the SKY Convention Centre.
But I met some very interesting people who had paid good money (well most had..) to be there.
First encounter was with the very newly appointed Chairman of the SOE ‘Crown Fibre Holdings’, Simon Allen.
CFH is somewhat similar to the Australian NBN Co.
Simon is a very calm, genuine, down-to-earth chap who has had a great career in both New Zealand and Australia, I would say he will be a very good man at the helm.

Then I met several people who quite surprisingly were involved with video production, e-learning via video, interactive video training for sports and commerce etc…
Conversation was convivial and constructive. I asked our video-centric people how they thought that their media would be delivered over fibre. They didn’t have a clue (don’t blame them).
I asked whether their media productions were in SD (standard definition) or in HD (high definition). The answer was always ’HD’. In fact anybody who buys a new video camera today will probably choose ’HD’ standard.
I also asked if they know what bandwidth a HD video signal required to be sent as IP video over fibre. Again, no clue.

We know that video will be the BIG bandwidth hog in coming years, because we don’t only have HD, we now have 3D banging on the door. (Even tons more bandwidth required).
So EVEN if we have much higher bandwidth internet over fibre, video of all kinds will be a hog on the fibre data link.

So I get back to my gospel on the ’third wavelength’. Nobody, at least here in New Zealand, seems to know about the widely-used option of transmitting broadcast TV and Radio over this 1550 nm third wavelength. You simply inject a third ’carrier’ wavelength on to the normal fibre which offloads all the Free-to-Air, and Satellite (SKY TV…) programming from the data channel.
You pick off that ’channel’ at the house end and send the TV/Radio around the home in perfect digital quality. And you offload the equivalent of some 5-10 Gbps of traffic from the data link.
New housing estates, high-rise buildings etc forbid individual antennas. How could you imagine a whole new housing estate that did not allow subscription to SKY TV?

So let’s start talking about the ’3rd wavelength’ for FTTH!
