RE: (SSIG) Taking the winning route
Ali,
I do not understand how you can be supportive of serial 850 nm
technology in one context and against it in another. You say "exploring 10
Gb serial with 850 nm VCSEL over 50/125 um at 100 m satisfies critical
market need at low cost." I agree. The same benefits apply to building
backbones up to 300 m in length.

I would agree that PMD solution should be based on existing MMF and
SMF. At the cost of
pulling new high bandwidth fiber, just pull SMF and operate at 1300
nm.

But exploring 10 Gb serial with 850 nm VCSEL over 50/125 um at 100 m
satisfies critical market
need at low cost.
