Outline
l Short Haul Copper Interconnect -  Typical Configuration
l Connector Proposal
l NEXT Measurements
l Summary
Typical Configuration

 Connector Proposal
n Standard should specify Single connector
n High Speed Serial Data Connector (HSSDC)  Style-2 Connector
NEXT Measurement Setup
NEXT Measurements
Eye Measurement with NEXT
15m uneq. cable without NEXT
15m uneq. cable with NEXT
30m eq. cable without NEXT
30m eq. cable with NEXT
Summary
l Specify only one Connector - HSSDC
l NEXT is not an issue
