Infiniband 4X/12X & CX4 Nx Cable Presentation Jan2009

  1. 1. NX High Performance Cables January 2009
  2. 2. Applications • InfiniBand • Ethernet 10GbaseCX4 • SAS – Serial Attached SCSI • Rapid I/O January 2009
  3. 3. NX Features • Direct attach of wire to cable plug contact via laser welding – Consistent low loss termination – Least disruptive to high speed signal • Wafer construction – Open access for wire termination – Large ground reference between pairs – Flexible design for special circuit sizes January 2009
  4. 4. NX Features • Superior inter-pair shielding – Inter-pair Ground Shield minimizes xtalk – Maintains ground reference plane for improved impedance control • Multiple back shell options – Straight and angled – Jack screw or pull to release latch – The most user friendly latch in the industry January 2009
  5. 5. Wafer Termination Process Inter-wafer Ground Shield Terminated Wafer is Added SubAssembly Ground shield commoning bus contact feature Unique cable design turns metallized side of Mylar on outside of wrap with drain wires external to differential wire pair The cable’s foil shield and the inter-wafer shield provide excellent signal isolation and multi-line crosstalk below 2% at risetimes of 50psec January 2009
  6. 6. Cable Cross Section Aluminized Mylar on Aluminized Mylar on Drain Wire Inside of Twin-Ax Shield Outside of Twin-Ax Shield Twin-Ax Typical Construction Twin-Ax Cinch / Meritec Construction Asymmetric Electrical Field Symmetric Electrical Field January 2009
  7. 7. Wire Termination Wafer Body Heat Staked Differential Wire Strain Contact Pair Relief Welded terminations on all signal lines January 2009
  8. 8. Terminated Wafer Array January 2009
  9. 9. Connector Assembly Process Wafers are stacked and pinned together to form Connector January 2009
  10. 10. Connector Assembly Process Ground shield commoning bus is added and ground drain wires are attached to the commoning bus January 2009
  11. 11. Connector Assembly Process After wafer stacking and assembly, the stack is over molded to provide strain relief for the wires and ground bus and insulate the cable shield from the backshell January 2009
  12. 12. The Difference - Cinch NX Competitor Cinch NX January 2009
  13. 13. NX Cable Backshell Options Angled Jackscrew Angled Latch Right or left exit Right or left exit Z-axis jackscrew (also available in latch version) Straight Jackscrew Straight Latch 12X Jackscrew (also available in latch version) January 2009
  14. 14. Competitive Latching The Gore latch requires the installer to push the latch mechanism forward either before or after plugging to activate and close the latches. January 2009
  15. 15. Competitive Latching Gore cable plugged in to a switch with only one of the latches actuated and latched Gore cable plugged in to switch with neither latch actuated. January 2009
  16. 16. Cable Handling - Gore Eyeopenner+ cable supplied by Gore is made with foamed Teflon dielectric surrounding the conductors. While this is an excellent dielectric, it presents handling issues the NX cable construction does not. This label appears on each cable that Gore ships advising the installer to “handle with care” – a requirement that is not very practical for an installer in a data center. January 2009
  17. 17. Competitive Latching If the switch is installed on a shelf or near an obstruction, it is nearly impossible to grasp cable plug latch release. January 2009
  18. 18. Competitive Latching The Molex pinch latch design can cause inadvertent unlatching of adjacent connector. January 2009
  19. 19. Cinch Latch Pull The Cinch latch pull is easily accessible even when obstructions make competitive latch release bars difficult or impossible to grasp. The design features an audible click when fully plugged indicating it is latched. Cinch NX Cable January 2009
  20. 20. Cinch Latch Options Standard Straight Angled Belly to Belly January 2009
  21. 21. NX High Speed Performance In-depth Information can be provide to customer when requested that shows competition vs. Cinch. January 2009
  22. 22. Reference Cable Lengths 10dB Cables in Worst Switch Port January 2009
  23. 23. Conclusions Parameter Result S21 • Best margin S11 • Best margin XTLK • Lowest Zo • Best control ILD • Tightest grouping Skew • Least variation Variation • Smallest delta January 2009
  24. 24. Conclusions • So What? • Why are these differences so important? January 2009
  25. 25. Conclusions • Extended distance without EQ – Less expensive • Consistent performance – Cable to cable – Lot to lot • September 2008 IBTA Plugfest – 10 DDR cables listed – 5 QDR cables listed • The most backshell options in the industry • The most user friendly latch system January 2009
  26. 26. January 2009
  27. 27. January 2009
  28. 28. Future Products January 2009
  29. 29. Roadmap Connectors • QSFP – Passive – Passive EQ – Active EQ • SFP/SFP+ • miniSAS • CXP 12X • Cinch is formulating designs currently January 2009
  30. 30. Thank You January 2009
