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.

SFP+ High Speed Copper Cable Assemblies
Active SFP+ Cable Assemblies
SFF-8431 requires active SFP+ cable assemblies to meet an output eye mask requirement when a minimal eye is transmitted
through the cable assembly. The input eye mask is measured by transmitting a 10.3125 Gbps PRBS 231-1 signal into a module
compliance test fixture and measuring the eye pattern through the mated host compliance test fixture. Once the input signal
is established, the cable assemblies are measured through the module compliance test fixture. All cable assemblies meet
the bit error rate requirement of 1x10-12. This design allows for output de-emphasis and signal amplitude to be adjusted to
accomodate customer requirements.

What wire gauge is required?
Tyco Electronics offers SFP+ cable assemblies in wire gauges
#24 through #32 to support customers’ specific cable routing
requirements. Smaller wire gauges results in reduced weight,
improved airflow and a more flexible cable for ease of routing.
