tom> what does [...] have to do with Moore's Law?
absolutely nothing.
the more data you can compute because of moore s Law the more you have to send trough copper or fiber. that s the bottleneck that is mentioned when talking about datalink and sip.
but don t worry. according to the white paper we combine the advantages of sip. (single mode usage) with the advantages of vcsel. so there s no competition out there for a while.
