Don’t want to double the R&D effort
•Optimizing R&D effort is definitely a good thing
– Did we learn anything from 10GE?
• Should we have a transceiver MSA before the standard is complete?
• Are the components cost-effective and manufacturable?
– 40GE doesn’t need to double R&D Effort but new chips will need to
be developed
•Development at the 40G optical layer is almost complete for
some companies
– Some companies are still researching it
•40GE will be an intermediate step towards 100GE that will aid in
quicker development of 100GE transceivers
