Can K23 Support PCIe 5.0?

The laboratory measurement can achieve full speed of PCIe 5.0,The picture below is the test result

Q&A:

Is there any EMI shielding for Cable?

With metal shield. The extender utilizes the latest materials for EMI shielding with five sole flat cables design. This technique allows each cable to be fully covered by electromagnetic interference shielding with conducting polymer to guard against incoming or outgoing emissions of electromagnetic frequencies, minimize disturbance and degradation on performance, and reduce the weight of the extender.

What is the thickness of the cable? Is it soft? Can it be bent?

The wire is the fifth generation PCIe dedicated wire independently developed by ADT, with a diameter of only 0.8mm, which can be bent freely without affecting its use.
