RE: PAM5 Objectives


Rich,

Thanks for the comments.

Which SMF objectives do you think PAM5 should address?  2 + 10km, or all
three?  Can PAM5 address the 40km objective (which now needs to compete with
60-80km solutions...)?

In my mind, low cost over the installed base is the most attractive
possibility for PAM5.  On the other hand, a single PMD that could meet all
802.3ae objectives would also be attractive, though I can't comment on
feasibility.

	Pat,

	A few minor conmments:

	1) I agree with Jay's comments regarding power consumption
	2) PAM5 solutions must also be significantly cheaper than Serial
(<1/2). The
	first bullet says "installed base" solutions which alludes to 62.5
um MMF.
	Serial doesn't address these. However, PAM5 should also address SMF
at <1/2 cost
	of Serial or WWDM. 

	Best Regards,
	Rich
