SFP+ Passive DAC Cable Assemblies are intelligent cables

The same host port cage can accept optical transceivers or direct attach cable assemblies. The back of the paddle card has pads which form the contacts to the 20 pin host connector inside the cage. The connector has an EMI shroud that provides 360 degrees of contact with the host cage to ensure excellent EMI immunity.
Note that the Panduit?
 10Gig SFP+ Passive DAC Cable Assembly lengths are measured from cable connector tip- to-tip. However, much of the connector is inserted into the host port. Therefore one may wish to add approximately 47mm or 1.87 inches to each end or approximately 0.1m total to port-to-port length and cord routing calculations.
Panduit? 10Gig SFP+ Passive DAC Cable Assemblies are intelligent cables. The connector has an integrated EEPROM with information populated in registers that is provided to the active equipment when queried through an I2C bus Most active equipment port allow for interchangeable types of me to be plugged into its ports. The registers in the EEPROM provide a method for the connector to
identify itself as an sfpcables.com SFP+ passive copper module to allow the active equipment to operate in the proper mode. Other information contained in the memory reg Panduit10Gig SFP+ Direct Attach Copper Cable Assemblies are intelligent cables.
