What Qing asks

One dense message. Five is the whole budget per supplier reply, so the questions that decide comparability go first.

59
Decides comparability — a quote missing these cannot be ranked
  1. 1.

    是无源 DAC、有源铜缆 ACC（Redriver）、有源电缆 AEC（Retimer）还是 AOC 有源光缆？

    Passive DAC, active copper ACC (redriver), active electrical AEC (retimer), or AOC?

    Four different price, power, reach and export-classification profiles under one word 'cable'

  2. 2.

    两端接口分别是什么（OSFP / QSFP-DD / QSFP112 / QSFP28 / SFP28）？是直连还是拆分（1分2 / 1分4）？

    What connector at each end (OSFP / QSFP-DD / QSFP112 / QSFP28 / SFP28), and straight-through or breakout (1:2 / 1:4)?

    A breakout cable also requires the switch port to be configured in breakout mode

  3. 3.

    需要哪些长度规格（0.5/1/1.5/2/2.5/3/5m）？各长度的最小起订量和交期档位是否不同？

    Which lengths (0.5/1/1.5/2/2.5/3/5m)? Do MOQ tiers differ by length?

    Fixed-length assemblies; a length survey error is unrecoverable after delivery

  4. 4.

    线规是多少 AWG（26/28/30）？最小弯曲半径是多少？铜线是自产还是外购？

    Conductor gauge in AWG (26/28/30)? Minimum bend radius? Is the bare copper made in-house or bought in?

    Gauge sets both electrical reach and how much cable fits in the manager; thicker is not automatically better

  5. 5.

    单通道速率是 25G NRZ、50G PAM4、100G PAM4 还是 200G PAM4？是否已通过对应速率的插损/回损测试？

    Per-lane rate: 25G NRZ, 50G PAM4, 100G PAM4 or 200G PAM4? Has it passed insertion/return-loss testing at that rate?

    224G-per-lane class cables are a genuinely different manufacturing problem from 112G

  6. 6.

    线缆两端的 EEPROM 兼容码分别要写成哪家？两端可否写不同厂商的码（例如一端思科一端 H3C）？

    What compatibility code goes in the EEPROM at each end? Can the two ends carry different vendor codes (e.g. Cisco at one end, H3C at the other)?

    The trap buyers miss: a DAC has two independent codes, and a mixed-vendor rack needs asymmetric coding

Ranking inputs
  1. 7.

    ACC/AEC 内置的 Redriver 或 Retimer 芯片是哪家哪个型号？是否有该芯片厂商的授权或专利许可？

    Which redriver/retimer chip vendor and part is inside the ACC/AEC? Do you hold a licence or authorisation from that chip vendor?

  2. 8.

    AEC/ACC 的附加时延是多少纳秒？单端功耗多少瓦？是否具备链路防抖动（flap）机制？

    Added latency in ns for the AEC/ACC? Power per end in watts? Any link-flap suppression feature?

  3. 9.

    外被材质与阻燃等级是什么（LSZH 低烟无卤 / CMP 阻燃 / CM）？是否符合目的国机房消防要求？

    Jacket material and fire rating (LSZH / CMP plenum / CM)? Does it meet the destination country's data-hall fire code?

  4. 10.

    拉手带长度是多少？在满配 64 口 OSFP 面板上能否单手拔插？线缆外径和最小安装弯曲半径是多少毫米？在理线器内的实际占用如何？

    Pull-tab length? Can a module be removed single-handed on a fully populated 64-port OSFP faceplate? Cable OD and minimum installed bend radius in mm, and what does that mean for cable-manager fill?

How buyers get burned here

Category-specific, from research rather than generic advice

  • Assuming 'not US-origin' means 'not subject to the EAR'. The Advanced Computing FDPR at 734.9(h) captures foreign-produced 3A090/4A090/.z items made with listed US technology or software, or on a plant derived from it. That covers essentially all leading-edge logic on earth. De minimis analysis never even begins for an FDPR-captured item.
  • Assuming a Chinese trading company can lawfully resell a controlled accelerator abroad. It cannot: 742.6(b)(10)(iii) is presumption of denial for all reexports and for D:5/Macau-headquartered entities, and License Exception ACA at 740.8 expressly excludes entities headquartered in — or ultimately parented in — D:5 or Macau. There is no structure that fixes this.
  • Reading the January 2026 case-by-case rule as 'H200 is now sellable to China'. It permits a LICENSED US EXPORTER to apply, with four certifications including a 50%-of-US-volume cap and mandatory independent US-lab pre-export verification. It changed nothing about reexport from China, and left presumption of denial fully intact for D:5/Macau-headquartered buyers.
  • Believing the AI Diffusion Rule was rescinded and its machinery is gone. It was never rescinded in the Federal Register: 740.27 (AIA), 740.28 (ACM), 740.29 (LPP), Supplement 5 to Part 740 and the 790,000,000 TPP country allocations are all still codified at 2026-09-01. BIS announced non-enforcement of its NEW requirements in May 2025, but the 2026-05-31 guidance confirms the pre-existing November-2023 headquarters-based licence requirement IS enforced, and the 2026-06-17 FAQ extends it to .z items.
  • Treating the Affiliates Rule as dead. It is STAYED, not repealed — 2025-19846 stays the 2025-09-30 IFR until 2026-11-09, roughly two months from now. Build the 50%-ownership aggregation logic now behind a flag. Note also that FDPR footnote 5 already carries its own surviving 50%-ownership provision, and OFAC's own 50% Rule never went away.
  • Screening the brand instead of the legal entity. Entity List designations are entity-specific: 'Inspur (Beijing) Electronic Information Industry' is listed while other Inspur group companies are not, and several distinct Fudan Microelectronics entities were listed separately in September 2025. Screen the unified social credit code on the contract, plus every alias.
  • Ignoring alias sprawl. The September 2025 additions show entities with up to sixteen aliases, and the four NetForward / Nanfei entities were listed across four cities. A single-string name match will miss most of them.
