What the data for this category looks like
The data for optical module intelligent due diligence reports primarily comes from supplier official specification sheets, industry standardized technical documents, third-party compliance test reports, and supply chain filing information. Update cycles are adjusted based on supplier model iterations, industry standard revisions, or compliance requirement updates, with no fixed uniform schedule. Document structures include core model parameters, manufacturer qualifications, compliance certification information, supply chain traceability records, and failure analysis cases. Fields include professional parameters such as transmission rate (unit: Gbps), operating wavelength (unit: nm), rated power consumption (unit: W), interface type, and certification number. Some documents include structured tables and image attachments.
What constraints these characteristics impose on knowledge base retrieval and recall
The multi-dimensional professional parameters and structured content of optical module due diligence reports require retrieval and recall to prioritize exact field matching, to avoid irrelevant results from broad full-text retrieval. The non-fixed update cycle means the knowledge base must support incremental synchronization. It should only update changed content, not perform full re-parsing, to reduce storage and computing overhead. A large number of professional model numbers and terms require custom tokenization rules, to ensure full recognition of full model names and parameter units. Cross-document linked supply chain and compliance data requires retrieval and recall to associate information from different sources, to improve result completeness.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Optical module due diligence reports contain long parameter descriptions and model explanations. This segment length can cover complete parameter units and avoid split breaks |
similarityThreshold | 0.72–0.85 | Professional matching requirements for optical module models and parameters are high. This range filters low-relevance non-professional search results |
recallTopK | Top 8–12 results | The optical module category has multiple parameter dimensions. A sufficient candidate set must be recalled for subsequent reranking and filtering |
UPLOAD_FILE_MAX_SIZE | 600 MB | Single optical module due diligence reports include multiple attachments such as test reports and certification certificates. This upper limit supports batch upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Optical module documents contain large numbers of tables and structured data, which take longer to parse. This duration covers the complete parsing process |
rerankTopK | Top 3–5 results | Only the most relevant core parameters and compliance information should be retained, to avoid redundant results interfering with large model output |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: Images in document knowledge bases created using localFile display as expired links. Cause: No knowledge base attachment permanent storage policy is configured. Default generated temporary links have an expiration date.
- Issue: A large number of generalized content unrelated to the target optical module model appears in search results. Cause:
similarityThresholdwas not adjusted to a reasonable range. Low-relevance non-professional documents were mistakenly included in the recall set. - Issue: Knowledge base parsing times out, returning status code 504. Cause:
PARSE_FILE_TIMEOUT_SECONDSwas not set to a duration adapted to optical module document parsing. The default duration is insufficient to complete structured table and parameter parsing.
How to confirm configurations are set correctly
- Upload a single complete optical module due diligence report. View the segmented content after parsing. Confirm that core parameters are not split and broken. Verify the configuration effect of
chunkSize. - Enter a professional query such as "200G optical module operating wavelength range". Check the relevance of recall results. Adjust
similarityThresholdto a range that meets business requirements. - Batch upload multiple optical module documents from different manufacturers. Confirm that all documents have completed parsing with no timeout errors. Verify the configurations of
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDS. - View the returned recall count and reranking results after searching. Confirm that
recallTopKandrerankTopKconfigurations meet output requirements.
