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

Dear Francois Menard,

 

I have contacted major Korea telcoes that started massive deployment of 1G EPON this year.

I have found out that all of them have no plan to support the video overlay.

For 10G EPON, they are just interested in split ratio more than 1G EPON(the more, the better)

So I think that PR-20/10 will be very small or useless for commercial deployment in Korea.

I am wondering if there is any different opinion about it.

 

Sincerely yours,

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!
