Re: [EFM] [Forecasts on 1 GE from NW]
Although I am interested in 1 GE P2P over a single fiber, that is after all,
the degenerative case for 1 G EPON, so we must concentrate on both. Our
objectives already specify 1000 Base-X with extended temp range optics (and
in practice, at least the clocking functional block as well at the ONU) AND
PHY for PON @ 1 G which will also require extended temp range components at
the ONU so except for flux budget, the L1 issues are similar.
