What the data for this category looks like
Data sources for optical module research reports include communication industry institute reports from securities firms, industry allocation research reports from financial institutions, public statistical documents from communication industry associations, and technical white papers from optical module supply chain manufacturers. Update cycles primarily follow quarterly industry research reports and semi-annual supply and demand reports, with temporary technical documents released alongside new product launches. Document structures typically include parameter summaries, core indicator tables, downstream application analysis, and price trend chapters. Core fields include transmission rate (unit: Gbps), packaging form, power consumption (unit: W), wavelength (unit: nm), and market size. Some documents include link calculation formulas and charts.
What constraints do these characteristics impose on document parsing and chunking?
Tables and precise numerical values make up a large share of optical module research reports. Parsing must fully retain table structures and field correspondence, and avoid splitting content that binds parameters and their units. If technical formulas included in documents are not parsed accurately, core logic for link calculations will be lost. Parameters from multiple research reports are scattered across different sections. Chunking must retain contextual associations, and avoid separating cross-paragraph parameter explanations. Large research report collections have large file sizes and many pages. Parsing must accommodate longer processing times and upload limits.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Optical module research reports contain a large number of parameter comparison tables. Table structures and field correspondence must be retained |
CHUNK_MAX_SIZE | 800–1200 characters | Most optical module parameters are bound to precise numerical values and units. Excessively long chunks will break parameter associations, and this range aligns with retrieval context length requirements |
PARSE_FORMULA_ENABLE | Enabled | Some research reports include formulas for optical module link loss and bandwidth calculation. Formula content must be parsed accurately |
DOC_SPLIT_BY_FILE | Enabled | When multiple optical module research reports are uploaded, chunk boundaries must be divided per individual document to avoid mixing content across documents |
RECALL_CHUNK_TOP_K | Top 6–8 entries | Core parameters of optical module research reports are scattered across different sections. Sufficient context must be recalled to associate complete information |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large optical module industry research report collections may include multi-page charts and nested tables. Parsing time must be accommodated |
UPLOAD_FILE_MAX_SIZE | 200 MB | Single collections of optical module supply chain research reports typically have large file sizes. Upload limits must be relaxed |
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. It is recommended to test against your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: After uploading an optical module research report, some keywords cannot be recalled. Normal recall works after creating a new knowledge base. Cause:
PARSE_TABLE_ENABLEwas not enabled during the first upload. This caused the parameter tables in the research report to not be parsed correctly, and valid chunks could not be generated. - Symptom: After uploading multiple optical module research reports, parameter information cannot be extracted per individual document. Cause: The
DOC_SPLIT_BY_FILEconfiguration was not enabled. This caused all documents to be merged into chunks, losing contextual boundaries for individual documents. - Symptom: After uploading an optical module research report, accurate parameter values cannot be returned during question answering. Cause:
CHUNK_MAX_SIZEwas set too large. Chunks for different parameters were merged, preventing precise matching of target parameters during retrieval.
How to Verify Correct Configuration
- Upload a small optical module research report PDF, and view the parsed chunk list. Confirm that table and formula content has been fully extracted.
- Enter core optical module parameter keywords, and retrieve chunk results. Confirm that recalled chunks include complete parameters and contextual associations.
- Upload multiple optical module research reports, and view the chunk list. Confirm that chunks for each document are divided with separate boundaries.
- Upload a large research report collection, and confirm that no timeout errors occur during upload and parsing processes.
