What the data for this category looks like
Optical module research report data comes from communications industry sell-side research reports, public technical whitepapers from optical module manufacturers, and technical specifications released by industry standard organizations. The update schedule follows new optical module product launches, industry standard iterations, and quarterly industry chain research results, with no fixed cycle. A single research report document typically includes structured fields such as model specifications, transmission rate (unit: Gbps), operating temperature range (unit: ℃), power consumption (unit: W), application scenarios, and upstream and downstream industry chain analysis. Some documents include test data and performance comparison tables.
Constraints on knowledge base retrieval and reranking
The large number of structured parameter fields with fixed units requires precise matching of parameter names and units during retrieval, to avoid recall bias caused by semantic ambiguity. Non-fixed update cycles require configuration of an incremental update mechanism to synchronize the latest optical module technical parameters and industry trends. Documents contain many professional tables and long paragraphs; segment processing must avoid splitting parameter groups, or critical context will be lost. Single document lengths vary widely, so parsing and retrieval logic must adapt to different lengths.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Adapts to the average length of parameter groups and paragraphs in optical module research reports, avoiding splitting complete parameter description blocks |
recall_count | Top 6–8 results | Covers parameter information across different dimensions in optical module research reports, avoiding omission of key technical details |
similarity_threshold | 0.75–0.85 | Balances precise matching and recall coverage, filters irrelevant generic industry research report content |
rerank_return_count | Top 3–5 results | Focuses on core parameter fragments most relevant to the query, reducing interference from redundant information |
UPLOAD_FILE_MAX_SIZE | 200 MB | Adapts to the common size of single optical module research report documents, avoiding upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Provides sufficient time for parsing and structured processing of long documents, avoiding timeout interruptions |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: Reranked return results are empty or only return 1 result. Cause: The
rerank_return_countparameter is not configured correctly, or the reranker model failed to load. - Symptom: Retrieval results include content unrelated to the query parameters. Cause: The similarity threshold is set too low, recalling non-precisely matched research report fragments.
- Symptom: Parsing timeout errors trigger when uploading optical module research reports. Cause:
PARSE_FILE_TIMEOUT_SECONDSis set too short, failing to adapt to the parsing needs of long documents.
How to Verify Correct Configuration
- Upload a research report document containing optical module parameters, check that parsed segments retain complete parameter names and units.
- Initiate a query that includes specific optical module models and parameters, verify that the number of returned recall results falls within the configured
recall_countrange. - Check system operation logs to confirm that the reranker model loads normally and returns reranked results.
- Test batch uploading multiple optical module research reports of different lengths, confirm that the
UPLOAD_FILE_MAX_SIZElimit is not triggered.
