Re: 10 GbE en MASse PMD, Historically...
Rich-
100BASE-TX was not a case of "engineered brand new technology"
We stole it fair and square from FDDI (TP-PMD). Perhaps you were thinking
of 100BASE-T4 or 100BASE-T2 both of which were new technology but didn't
make it in the market.
You could argue 10BASE-T either way. There was extensive proprietary
product out there (LattisNet-UTP) and the group had already done work on 1
Mb/s StarLAN (1BASE5) but the signaling was a new design, the last one that
we have done that was a success. The jury is still out on 1000BASE-T.
