Transceiver Empowering Industrial 4.0 Factory Networking

In the construction of Industry 4.0 factory networks, optical modules serve as core optoelectronic conversion devices. Their selection and deployment span the entire network construction process, primarily addressing the limitations of traditional copper cabling networks—such as insufficient bandwidth and poor interference resistance—to provide highly reliable optoelectronic interconnectivity for real-time control, big data acquisition, and AI analysis in smart manufacturing. Their implementation must adhere to the core process of ‘requirements matching – tiered deployment – validation and optimisation – operational maintenance assurance’. Each stage relies on the industrial-grade characteristics of optical modules (electromagnetic compatibility (EMC), extended temperature range of -40°C to +85°C, and long-distance transmission) to achieve technical realisation.


Phase One: Requirements Research and Solution Design, with the core objective being precise alignment with scenario requirements. Optical module selection must be determined based on factory scale, equipment types (robots/sensors/AGVs, etc), transmission distances and other factors: - Device Layer: For terminal interconnection needs, 10G SFP+/25G SFP28 optical module are selected, compatible with the IEEE 802.3ba protocol to ensure nanosecond-level synchronisation, supporting robot collaboration and high-precision control; For the network layer addressing cross-area aggregation, 100G QSFP28 LR4 optical module paired with standard single-mode fibre enable multi-facility data interconnection within 10km. The core layer, catering to big data processing, deploys 400G QSFP-DD/800G OSFP optical module to fulfil real-time analysis of petabyte-scale data.

Phase Two: Deployment Implementation and Technology Convergence, primarily ensuring end-to-end network connectivity and value enhancement. Implementation requires scenario-specific convergence solutions: - Mobile terminal scenarios deploy ‘5G private networks + optical networks’, with 25G optical module supporting 5G fronthaul BBU-RRU interconnectivity for flexible AGV access; For small-to-medium factory scenarios, adopt an F5G all-optical network OLT+ONU passive architecture, minimising cabling costs and energy consumption through simplified optical module deployment; For critical control scenarios (precision manufacturing/smart grids), enable optical module Frame Replication Elimination (FRER) technology to prevent production interruptions.

Phase Three: Validation, Optimisation and Operational Assurance, primarily focused on ensuring long-term network stability. Industrial practice validates construction outcomes: networks built with optical modules deliver enhanced production efficiency, reduced equipment failure rates and lower operational costs. Subsequent maintenance leverages the Digital Diagnostic Monitoring (DDM) capabilities of optical module to monitor parameters such as power and temperature in real time. Combined with AI algorithms for predictive fault detection, this further reduces operational complexity, establishing a robust and reliable network infrastructure foundation for industrial digital transformation.
