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.

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 cable lengths are required? Tyco Electronics SFP+ copper passive and active cable assemblies Cable length and wire gauge are related to the performance meet the signal integrity requirements defined by the industry MSA characteristics of the cable assembly. Longer cable lengths SFF-8431. We can custom engineer cable assemblies to meet the require heavier wire gauge, while shorter cable lengths can requirements of a customer’s specific system architecture. utilize a smaller gauge cable. Are passive or active cable assemblies required? Are there any special customer requirements? Passive cables have no signal amplification in the assembly and Examples of special customer requirements include: custom cable rely on host system Electronic Dispersion Compensation (EDC) for lengths, EEPROM programming, labeling and packaging, pull tab signal amplification/equalization. Active cable assemblies have signal length and color, company logo, signal output de-emphasis, and amplification and equalization built into the assembly. Active cable signal output amplitude. We can custom engineer cables to assemblies are typically used in host systems that do not employ specific customer system architecture. EDC. This solution can be a cost savings to the customer. 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. FOR MORE INFORMATION TE Technical Support USA: Canada: Mexico Latin/S.
