RE: [EFM] [Forecasts on 1 GE from NW]


1 GE P2P over a single fiber, IS NOT, the degenerative case for 1 G
EPON(no burst). It should cost the same "bananas" as single mode 1000
Base-X Ext. Temp.  

Single wavelength P2P, 1310/1310 is less expensive (and less inventory).
Even two wavelength P2P is not a derivative at the OLT side, if cost is
king, which it is indeed.

Greetings Seto:
Although I am interested in 1 GE P2P over a single fiber, that is after
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
in practice, at least the clocking functional block as well at the ONU)
PHY for PON @ 1 G which will also require extended temp range components
the ONU so except for flux budget, the L1 issues are similar.
