SFP+ High Speed Copper Cable Assemblies
Tyco Electronics SFP+ direct attach copper cable assemblies are a high speed, cost effective
alternative to fiber optics in 10Gb Ethernet, 8Gb Fibre Channel and InfiniBand applications.
SFP+ copper cable assemblies enable hardware OEMs and data center operators to achieve high
port density and configurability at a low cost and reduced power requirement. Tyco Electronics
SFP+ copper assemblies meet the industry MSA for signal integrity performance.

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.
