VALIDATION GUIDE · AI CLUSTER

AI Cluster Optical Interconnect Validation Checklist

Do not scale an optical BOM from a catalog match alone. Freeze the endpoint, port, module, fiber and software context; validate a representative link; then preserve the configuration used for volume deployment.

IdentityExact platform + port + optical PN
ConfigurationFirmware + FEC + port mode
Physical PathFiber + connector + polarity + reach
EvidenceDiagnostics + link test + frozen result

Validate the whole link, not only the transceiver

01 / PLATFORMFreeze endpoint identityRecord exact switch, NIC / HCA / DPU, server and target port.
02 / PORT MODEFreeze lane and breakout modeRecord native rate, breakout mapping and port configuration.
03 / OPTICFreeze exact optical PNRecord form factor, optical architecture, reach and module revision when relevant.
04 / FIBERFreeze the physical pathConnector, fiber type, polarity, patch panels and measured route length.
05 / SOFTWAREFreeze firmware and FEC contextCapture software versions and settings that affect link behavior.
06 / DIAGNOSTICSRead module diagnosticsUse supported CMIS / management telemetry to verify module identity and operating state.
07 / LINK TESTRun representative trafficCheck link stability and error behavior under the project test condition.
08 / FREEZEFreeze the validated combinationRecord what passed before moving from sample to volume deployment.

What should be captured after a successful validation

Platform evidence

  • Exact endpoint models and ports
  • Firmware / NOS / driver versions where relevant
  • Port rate, FEC and breakout configuration
  • Exact optical PN and revision

Link evidence

  • Fiber and connector path
  • Module diagnostics / telemetry snapshot
  • Test method and observed link state
  • Date, sample quantity and result

Use CMIS data as evidence—not as a substitute for link validation

OIF CMIS defines a common management interface for pluggable modules including QSFP-DD and OSFP. It can expose module identity, state and diagnostics, but a valid management readout alone does not prove end-to-end interoperability.

OIF OFFICIAL

CMIS 5.3

Use the current public CMIS specification as the management-interface reference where the module and host support it.

PROJECT CONTROL

Configuration Freeze

Preserve the exact platform, software, port, optic and fiber combination that passed the agreed validation.

Validation boundary: a successful sample test applies to the recorded configuration. Any meaningful change in platform, firmware, port mode, optical PN or fiber path should trigger a controlled re-check.
