RE: 3PMD Proposal

I agree with Howard's points.

The other thing that I've been hearing that concerns me is this
representation that the new MMF used for 1000BASE-SX will work for a 10 GbE
850nm solution. Without knowing the length of new MMF cable being installed,
that assertion cannot be guaranteed.

	Can you provide some numbers to substantiate this assertion:

	What constitutes "a significant and growing installed base of the
	multi-mode fiber?"

	Can you show us a timeline, going out for the next five years, with
	your projections of the percentage penetration for the new fiber in 
	both the horizontal and backbone applications?
