News from Japan: FTTH Taking Over DSL and Video over RF for GEPON

Posted on 11.30.05

Nyquist Capital has a blog entry showing a couple slides from a recent NTT presentation. The big news is that new FTTH installations are overtaking new DSL installations. Pricing is $40/month for a FTTH GEPON internet connection. This is comparable in price to Verizon Fios, but access speed is much higher.

The second slide is perhaps more interesting. It shows that to offer video service, NTT is running video over RF on a separate wavelength to the premises. To me this indicates that GEPON is not quite there yet for Video over IP, and GPON then has a significant advantage in this area. Does anyone have more information on the "FM-converted multichannel video signal" RF transmission technology that NTT is using?

I am not sure of the slide you are looking at, but GE-PON is more then capable of IP video. The reason NTT has looked at RF overlay in the past is strictly due to regulation, and it is much more likely that they will do IP Video once they get relief. SBB/Yahoo already does IP Video over GE-PON, you can see it on their web page

Quite extrange indeed they would do video overlay on PON the way Verizon does in FIOS. In fact, in news posted in past april’05 in convergedigest (http://www.convergedigest.com/IPTV/iptvarticle.asp?ID=14447), NTT West and Skystream announced the use of the latter’s IPTV headends to deliver such service. Seems unlikely to use IP to be broadcast in 1550nm as RF channels are transmitted. Maybe the slide shows a trial, but seems more likely that this is not true. EPON is capable of delivering unicast video to its customers: think that most pessimistic speed/user ratio would be around 500Mbps for 32 customers, so no problem.
