RE: 3PMD Proposal is not enough




John,

This is great information. Thank you.

What assumptions are used?  What are the motivations for customer choice of
the new MMF?

1. Are they doing this to get greater distance at gigabit speeds?
2. Are they doing this to improve error rates at gigabit speeds?
3. Are they doing this because the new MMF is less expensive than existing
MMF?
4. Are they doing this because they expect P802.3ae to adopt an 850 nm
solution?
5. Other rationale?
