Cable and Connector Testing

• Cable and Connector Testing - Why ?
• Communications Loss
• Interop Problems
• Orlando 1999 - CCDWG
• Test Laboratory Selection
• Specification Review
• Product Delisting
• Group 6 Testing as a Starter
• Provisional Listing

5
Cable and Connector Testing

• Benefits of Compliance Testing
• The use of listed cables and connectors is
  required for devices to get on the Integrators
  List
• You must be listed in order to use the new logo
  which indicates that the cable is high speed
  capable.

Mini-B Connector Design Validation

• The Mini- B Cable and Connector minimum
  qualification test program
• The program consisted of 4 manufacturerswho
  agreed
• 1st - The Design
• 2nd - Submission of their first products for
  independent testing .
• And the players are
• ACON Marunix Mitsumi Molex
