What data for this category looks like
Optical module investment research data primarily comes from manufacturer official specifications, industry communication standard documents, supply chain centralized procurement announcements, patent literature, and third-party test reports. Update frequencies vary by scenario: manufacturer new product specifications are updated alongside product launches, supply chain quote data is updated weekly, and patent literature is indexed in real time. Document structures mostly use structured parameter tables, including core fields such as wavelength, transmission rate, power consumption, and package form. Attachments include test waveform charts and compliance certification documents. Units strictly follow industry standards: wavelength uses nm, transmission rate uses Gbps, and power consumption uses W.
What constraints do these characteristics impose on deployment and upgrade?
The multi-source and multi-format nature of optical module investment research data creates clear constraints for deployment and upgrade workflows. First, individual specification documents and bulk centralized procurement summary files are lengthy. Adjust parsing timeout and file upload limit parameters to avoid parsing interruptions. Second, frequently updated supply chain data requires adapting incremental synchronization logic during upgrades to reduce resource consumption from full synchronization operations. Third, the combination of specific industry units and multi-dimensional parameters requires strict alignment of knowledge base field mappings with industry standards to prevent parameter confusion. Additionally, test reports containing images require enabling image parsing capabilities, which adds complexity to deployment configuration.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Optical module specifications, test reports and similar documents have lengthy content; standard timeout durations cannot complete full parsing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single bulk centralized procurement Excel summary files may exceed standard upload limits, requiring adaptation for large file upload requirements |
Segment Length | 800–1200 characters | Single parameter descriptions in optical module parameter tables have moderate length; splitting text preserves complete parameter context and improves retrieval accuracy |
Recall Count | Top 8 entries | Investment research scenarios require coverage of multi-dimensional parameter comparisons; too many recalled entries increase context redundancy and reduce model inference efficiency |
Similarity Threshold | 0.75–0.85 | Products in the same optical module category have high parameter similarity; low-match irrelevant documents must be filtered to improve retrieval precision |
PARSE_ENABLE_IMAGE | Enabled | Some optical module test reports include waveform charts and package diagrams; image understanding models must be enabled to extract key information |
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 targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- After upgrading to version 4.9.5, calling the knowledge base API returns a
401 Unauthorizederror. The cause is failure to distinguish usage scenarios between application-specific keys and universal keys, and using a universal key for knowledge base calls bound to a specific application. - Local deployment versions cannot load the image understanding model when creating a universal knowledge base. The cause is failure to enable the
PARSE_ENABLE_IMAGEparameter in deployment configuration, or failure to configure the API key for the corresponding model. - Uploading an optical module specification returns a parsing failure log. The cause is that
UPLOAD_FILE_MAX_SIZEis set too small, preventing large specification files from completing upload and parsing.
How to confirm correct configuration
- A user uploads an optical module specification larger than 10MB, and checks if the parsing status shows
Completedwith no timeout or parsing failure prompts. - A user views the
Recall CountandSimilarity Thresholdparameters on the knowledge base settings page, and confirms they match the preset configuration. - A user calls the knowledge base retrieval interface, and verifies that the returned results include core parameters such as optical module wavelength and transmission rate, with no irrelevant documents included.
- A user views the current running version number on the system settings page after upgrading the version, and confirms it matches the target upgrade version.
