What Qing asks

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

68
Decides comparability — a quote missing these cannot be ranked
  1. 1.

    请确认封装形式：OSFP、OSFP-RHS、OSFP-XD、QSFP-DD800、QSFP-DD、QSFP112、QSFP56、QSFP28 还是 SFP28？OSFP 请说明是平顶还是带鳍散热盖。

    Confirm the form factor: OSFP, OSFP-RHS, OSFP-XD, QSFP-DD800, QSFP-DD, QSFP112, QSFP56, QSFP28 or SFP28? For OSFP, flat-top or finned-top heatsink?

    Cage and heatsink shape are a physical fit issue inside the switch; a wrong answer is a returned shipment

  2. 2.

    光口规格是 SR4/SR8、DR1/DR4/DR8、FR4/2xFR4、LR4 还是 ZR/ZR+？标称传输距离多少米/公里？对应单模还是多模光纤？

    Which optical spec: SR4/SR8, DR1/DR4/DR8, FR4/2xFR4, LR4, or ZR/ZR+? Rated reach in m/km, and singlemode or multimode?

    Defines the entire fibre plant; reach classes do not interoperate

  3. 3.

    电口和光口的通道配置分别是多少？例如 800G 是 8×100G 还是 4×200G？单波速率是 50G/100G/200G PAM4？

    What is the electrical and optical lane configuration — e.g. is 800G 8x100G or 4x200G? Per-lane rate (50G/100G/200G PAM4)?

    Must match the switch SerDes generation or the link never trains; two 800G modules can be electrically incompatible

  4. 4.

    光引擎采用 EML、硅光（SiPh）、VCSEL 还是 DFB 方案？

    Is the optical engine EML, silicon photonics, VCSEL or DFB?

    Drives power, yield and supply resilience; SiPh and EML versions of the same part number behave differently

  5. 5.

    DSP 型号与工艺节点（5nm/3nm）是什么？是否提供 LPO（无DSP）或 LRO（半重定时）版本？

    Which DSP part and process node (5nm/3nm)? Do you offer an LPO (DSP-free) or LRO (half-retimed) variant?

    3nm DSP cuts module power ~20%; also the component most likely to raise an export-classification question

  6. 6.

    满负荷典型功耗和最大功耗各是多少瓦？属于哪个功耗等级？

    Typical and maximum power draw in watts at full load, and which module power class?

    Switch cage power class caps what you can plug in; 64 modules turn a few watts into kilowatts

  7. 7.

    光纤接口是 双工LC、MPO-12 还是 MPO-16？端面是 UPC 还是 APC？

    Connector: duplex LC, MPO-12 or MPO-16? UPC or APC end-face?

    MPO-12 vs MPO-16 and UPC vs APC each silently invalidate an entire cable plant

  8. 8.

    需要烧录哪家的兼容码：思科、Arista、Juniper、NVIDIA、华为、H3C、锐捷还是通用原厂码？能否按我方指定设备型号逐台烧录并做上机验证？

    Which compatibility code should be burned in — Cisco, Arista, Juniper, NVIDIA, Huawei, H3C, Ruijie, or generic? Can you code to our exact switch models and bench-verify?

    The single biggest hidden variable in optics procurement; identical hardware, different EEPROM, different usability

  9. 9.

    MPO 接口是公头（有导针 pinned）还是母头（无导针 unpinned）？模块侧、跳线两端、主干光缆两端分别是什么？请按链路逐段确认。

    Is each MPO interface pinned (male, with guide pins) or unpinned (female)? Specify for the module port, both ends of the patch cord and both ends of the trunk, segment by segment.

    Two pinned or two unpinned ends physically cannot mate. Absent from the original field set and it invalidates a whole fibre plant as surely as APC/UPC does

  10. 10.

    模块管理接口遵循哪个版本：CMIS 4.0 / 5.0 / 5.2 还是 SFF-8636？我方交换机 NOS 只支持指定版本，能否提供对应版本的固件？

    Which management interface revision does the module implement — CMIS 4.0 / 5.0 / 5.2, or SFF-8636? Our switch NOS supports only specific revisions; can you supply firmware matching ours?

    A CMIS-revision mismatch produces a module that powers up but is unmanageable or never reaches high-power mode — indistinguishable from a dead module in the field

  11. 11.

    每个兼容码的最小烧录批量是多少？后续能否对已发货模块改码？改码是否需要寄回工厂、有无费用和批量门槛？同一订单能否混合多种兼容码？

    What is the minimum order quantity per compatibility code? Can already-shipped modules be re-coded, does that require return to the factory, and at what cost and batch minimum? Can one order mix several codes?

    Coding is a factory burn with its own MOQ; a buyer who splits 500 modules across six switch vendors may fail every per-code minimum and get a repriced order. This is the commercial half of the coding trap the report identified

  12. 12.

    该模块/线缆已在哪些交换机型号和具体 NOS 固件版本上做过上机验证？能否提供验证记录或视频？我方型号未在列表内的，能否先寄样验证再批量下单？

    On which exact switch models and NOS firmware versions has this module or cable been bench-verified? Can you supply the test record or video? If our model is not on the list, will you sample-verify before we place the volume order?

    Coding to a vendor name is not the same as working on a specific model at a specific firmware level; the firmware version is where coded optics most often fail

  13. 13.

    该模块用于拆分时，对端应搭配哪个具体型号（例如 400G-DR4 对 4 只 100G-DR）？两端是否必须同厂同批？跳线是 MPO 转 4×LC 还是 MPO 转 4×MPO？

    For breakout use, which exact far-end module does this pair with (e.g. 400G-DR4 to 4x 100G-DR)? Must both ends be same-vendor/same-batch? Is the harness MPO to 4xLC or MPO to 4xMPO?

    Breakout optics are bought as a pair plus a harness; ordering the head without the tail and the correct harness is the most common optics BOM error

Ranking inputs
  1. 14.

    激光器芯片和 DSP 分别是自产还是外购？供应商和型号能否告知？贵司是否有自有芯片产线？

    Are the laser chip and the DSP made in-house or bought in? Which vendor and part number? Do you operate your own chip fab?

  2. 15.

    该模块要求交换机侧开启哪种 FEC（RS-FEC KP4 / KR4 / 不需要）？关闭 FEC 时链路预算如何？

    Which FEC must the switch enable (RS-FEC KP4, KR4, or none)? What is the link budget with FEC off?

  3. 16.

    工作温度等级是商温（0~70℃）还是工业级（-40~85℃）？高密度满配时的壳温上限是多少？

    Commercial (0-70C) or industrial (-40 to 85C) grade? What is the case temperature limit in a fully populated chassis?

  4. 17.

    是否提供每只模块的出厂测试报告（TDECQ/眼图/接收灵敏度/光功率）和 100% 高温老化记录？序列号是否可追溯？

    Do you provide per-unit factory test data (TDECQ, eye, receive sensitivity, optical power) and 100% burn-in records, traceable by serial number?

  5. 18.

    质保多少个月？是否支持 DDM/DOM 数字诊断？RMA 流程和不良率承诺是怎样的？

    Warranty in months? Is DDM/DOM diagnostic monitoring supported? What is the RMA process and committed failure rate?

  6. 19.

    模块出厂固件版本号是多少？是否支持在线（CDB）固件升级？后续固件更新如何发布，是否免费？

    What firmware version ships on the module? Does it support in-service (CDB) firmware upgrade? How are later firmware updates distributed, and are they free?

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.
