AW: 3PMD Proposal


my personal concern is focusing on new MMFiber when talking about pulling new fiber.
We as a community of Fiber Optics supporters will run into similar argumentation as the copper industry does today where in the past fiber always has been sold as future proof.
How can we do the next step beyond 10GBE on MMF ?
So when pulling new fiber, my recommendation always would be single mode.

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?
