What the Data for This Category Looks Like
Optical module data sources include communication industry standard documents, original manufacturer specification sheets, third-party test reports, carrier bidding parameter libraries, and more. Update cadence fluctuates with new product launches by manufacturers and industry standard iterations. New product parameter documents are updated monthly. Industry standard documents are updated annually. Single document structures use standardized fields: model identifier, transmission rate, operating power consumption, operating temperature range, interface type, compliance certifications, and others. Corresponding units are Gbps, W, and ℃, respectively. Some high-end optical module documents also include link loss test data.
Constraints on the Citation Source and Traceability Link
Multi-source heterogeneous data sources require the traceability link to support cross-data source marking. This avoids confusing same-model parameter documents from different manufacturers. Frequently updated documents require the traceability system to support incremental updated version marking. This ensures referenced parameter data uses the latest available version. Standardized but numerous fields require precise positioning to the specific document segment where the target parameter is located during traceability. Long documents require segment processing, with traceability information bound to the corresponding segment. This avoids broadly referencing the entire document, and improves citation accuracy.
How to Configure Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 10 entries | Optical module parameter documents have numerous fields. Sufficient candidate documents must be recalled to cover relevant parameter groups |
Similarity threshold | 0.75-0.85 | Filter low-relevance non-optical module documents, and avoid recalling irrelevant communication device parameters |
Chunk size | 800-1200 characters | Ensure each segment contains a complete parameter set for a single optical module model, enabling precise citation source positioning |
Citation template | {{content}} Source: {{sourceName}}, Update Time: {{updateTime}} | Clearly mark the source document name and update time, meeting traceability requirements for investment research scenarios |
MAX_REFERENCE_TIMEOUT | 300 seconds | Adapt to the actual parsing time of optical module documents, and avoid traceability failure caused by parsing timeout |
Multi-source Recall Switch | Enabled | Support cross-manufacturer document source comparison, and avoid parameter bias from a single data source |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Analyze specific issues on a case-by-case basis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfiguration Issues
- Symptom: No citation source appears at the end of the generated answer. Cause: The
Citation templateconfiguration is not enabled, or the source placeholder is missing from the template. This prevents FastGPT from generating traceability information. - Symptom: Question and answer requests timeout and return error code 504. Cause: The
MAX_REFERENCE_TIMEOUTsetting value is lower than the actual parsing time of optical module documents. This causes the traceability link to time out before completion. - Symptom: Citation sources point to the wrong document version. Cause: Document version tracking configuration is not enabled. Only the latest uploaded document copy is retained, making it impossible to retrieve parameter information from historical versions.
How to Confirm Successful Configuration
- Upload an optical module original manufacturer specification sheet marked with an update time, initiate a query that includes specific model parameters, and check if traceability information including the document name and update time appears at the end of the answer.
- Enter the question and answer details page, view the recalled document list, and confirm that each cited source matches the uploaded document file name and update time.
- Adjust the
Similarity thresholdto 0.9, observe a reduction in the number of recalled results, and verify that the configuration parameter takes effect. - For versions 4.9.7 and above, confirm that the
Citation templateconfiguration item is available in the advanced AI configuration. Lower versions do not support this parameter. - Test consecutive queries for parameters of different optical module models, and confirm that the citation source for each answer corresponds to the document segment referenced in the query.
