Selection, compatibility, and alternative solutions reference and suggestions

In the design of high-speed PCIe systems, the selection of cable components needs to take into consideration factors such as interface type, channel count, length, signal rate, and device structural space. For 8KH8-0967-0500, the following are common selection and compatibility reference suggestions:

Key selection parameters

• PCIe channel count (x8/x16, etc.)

Cable Length (250mm, 500mm, etc.)

Connection method (Straddlemount / Card Edge)

Signal standard (PCIe Gen3 / Gen4)

Cable Impedance (typically about 85Ω)

2. Compatible Model Reference

In the same type of PCIe extension cables, refer to the interface and length requirements as needed:

  8KH8 series other length models

  •  PCIe x8 / x16 Twin Axial Extender Assemblies

• Same category Twinax high-speed extension line component

3. Recommendations for Domestic Substitute Solutions

For server, AI computing power equipment, or high-speed communication equipment manufacturers, there may be challenges in terms of lead time, cost, and supply chain stability with imported brand cable products. Therefore, during the design phase, it is advisable to consider:

  Adopting domestic Twin Axial high-speed cable structure

  Maintain PCIe interface compatibility design

Customized according to original factory harness size and impedance parameters

• Verify through Signal Integrity (SI) testing

By means of domestic substitution programs, cost structures can be optimized while maintaining performance, and supply chain stability can be enhanced.
