Context Before

Evidence

Nevertheless, it is still challenging to drive a PCIe Gen6 signal over around 500mm of PCB distance from the Strata Module to the front of the Orchid Module.

Context After

In addition to having high quality SerDes, proper signal integrity is still achievable by upgrading PCB materials.

② Atomic Claim

即便如此，要讓 PCIe Gen6 signal 從 Strata Module 經約 500mm 的 PCB 距離走到 Orchid Module 前端，仍然很有挑戰。
