Re: [8023-10GEPON] Wavelength plan for PR10/20 downstream

Japan market, one of the biggest market for EPON deployment, 1577nm will
be developed and used.

Bang on!

As the only provider of FTTH in Canada at this time, and as a provider who 
have chosen to stay with Dual-Play FTTH until we can do IPTV, I would be 
saddened to see 10GEPON take a large financial cost penalty, in order to 
ensure backward compatibility of 1550 RF Overlay.

If Japan is not going to go for it, we will not benefit from the large 
volume that our japanese friends can make happen for the rest of us on the 
planet.

I see no benefit in articulating the frequency plan for 10GEPON based on 
the requirement for RF Video Overlay.

Those that want to do RF Video Overlay can choose PLAN B.

We want PLAN A, and this one has to be the one which will have some 
initial volume to make the price come down quickly.

Thanks!
