Development and Perspective of High-Speed Twinaxial Copper Cabling Technology

By researching of the approved standards in Institute of Electrical and Electronics Engineers (IEEE), International Electrotechnical Commission (IEC), and Optical Internetworking Forum (OIF), current technologies of high-speed twinaxial copper assemblies, twinaxial cables, and connectors were summarized. Furthermore, technical challenges of the design, manufacture, and test of the next generation twinaxial copper cabling with 200 Gb·s⁻¹ or 400 Gb·s⁻¹ signaling rate per lane were discussed.
