What the data for this category looks like
Optical module yield rate data comes from three main sources: optical communication industry monitoring platforms, public bidding ledgers, and manufacturer shipment records. Two update schedules apply:
- Daily full-category yield rates are updated after market close each day
- Real-time market data is refreshed every 15 minutes
Data is packaged in JSON format, with a structure that includes optical module model, production batch, daily transaction unit price, unit cost, and yield rate proportion value. All fields have clear unit identifiers: transaction unit price and cost unit price are measured in yuan per unit, and yield rate is a unitless proportion value.
What constraints these characteristics impose on HTTP interfaces and external systems
Configure the interface to support multi-request aggregation to match the multi-source data nature. Configure a unified field matching rule to eliminate differences in model identifiers across data sources. Set the interface pull interval to adapt to the 15-minute update cycle of real-time market data, to avoid data lag or repeated pulls. Require external systems to strictly map units to prevent yield rate calculation deviations caused by unit conversion errors. Configure the interface to support filtering by model, to reduce invalid data transmission volume and lower processing pressure on external systems. Set a reasonable interface timeout threshold, as single multi-source data aggregation requests take a long time. This avoids early request interruption.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
api_request_timeout | 600 seconds | Multi-source data aggregation requests for optical modules take a long time. This duration covers response cycles for most scenarios and avoids early timeouts |
multi_source_merge_strategy | Average yield rate after deduplication by the model field | Minor differences exist in optical module model identifiers across different data sources. Unified matching and merging ensures data accuracy |
refresh_interval | 900 seconds | Adapts to the 15-minute update cycle of optical module real-time market data. Slightly shorter than the refresh cycle to ensure data timeliness |
field_mapping_rule | Map the third-party interface's trade_price to the system's trade_price, retain the yuan per unit unit | Optical module transaction unit price uses per unit as the standard unit. Strict mapping avoids unit conversion errors |
retry_max_times | 3 times | Optical module data sources may have temporary fluctuations. Multiple retries reduces the impact of single request failures |
filter_condition | Only pull valid yield rate records | Only optical module yield rate data that meets business requirements needs to be counted. Invalid records are filtered out |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: The interface returns a
400 Bad Requesterror. Cause: The exactmodelfield parameter was not passed as required. There are multiple detailed identifiers for optical module models, and fuzzy matching triggers the interface verification rule interception. - Symptom: The
yield_ratefield in pulled data is empty. Cause: Thefield_mapping_rulewas not configured. The third-party interface's yield rate field name does not match the system's preset fields, causing data to fail correct mapping to the target field. - Symptom: Interface requests frequently time out. Cause: The set
api_request_timeoutvalue is less than the actual interface response time. Single requests for multi-source optical module data take a long time, and insufficient timeout settings cause requests to be interrupted.
How to Verify Successful Configuration
- Call the configured HTTP interface, check if the returned results include preset fields such as
model,trade_price,yield_rate, and that field units match the configuration rules. - Check system operation logs, confirm that the number of interface request retries does not exceed the
retry_max_timesconfiguration value, and there are no consecutive failure records. - Compare the update time of third-party data sources with the system pull time, confirm that the pull interval meets the
refresh_intervalconfiguration requirements. - Apply the configured
filter_condition, check if the returned results only include optical module yield rate data that meets business requirements.
