Context Before
Let’s step through key features of Rubin’s networking and the architectures that are likely to be built around Rubin scale-up and scale-out networks.
Bi-directional SerDes for Scale-Up
Evidence
Each electrical lane is one differential pair (DP) consisting of two conductors that carry equal magnitude, and opposite polarity signals
Context After

② Atomic Claim
關於 SerDes：每個 electrical lane 是 1 組 differential pair（DP），由兩條 conductors 組成，傳送 magnitude 相同、polarity 相反的 signals。
