SFP+ Cable Assembly Part Number Selection Guide
SFP+ Cable Assembly : Specifications
SFP+ Cable Assembly : Electrical Performance
Passive SFP+ Cable Assemblies : WDP, VMA and VCR Measurements
A passive copper cable assembly will be compliant with the SFP+ MSA Rev 4.1 if the dWDP number is less than 6.75
dBe. The WDP measurements shown in the table below are for the indicated wire gauge and cable length of Tyco
Electronics production assemblies. Any cable with the same wire gauge and shorter length than the length listed
below will have a lower dWDP value.
To be compliant with SFF 8431 Rev 4.1, the VMA must be less than 4.5 dB and the VCR must be greater than 33 dB.
The VMA and VCR measurements shown in the table below are for the indicated wire gauge and cable length of
Tyco Electronics production assemblies. Any cable with the same wire gauge and shorter length than the length
listed below will also meet the VMA and VCR limits.
