At SH LINK, quality is the foundation of our business. We believe that consistent quality builds customer trust and long-term partnerships. Our quality system is designed to ensure every product we manufacture meets industry standards, from optical components to complete transceiver modules and network equipment.

We operate under a certified ISO 9001 Quality Management System, which covers every stage of production – from raw material inspection to final product testing. This ensures our customers receive products with reliable performance and long operational life. Our team strictly follows standardized procedures and quality protocols to minimize defects and maintain production efficiency.

• Strict supplier evaluation and raw material inspection
• Standardized production processes with clearly defined quality checkpoints
• In-process quality control for each manufacturing stage
• End-to-end testing and final inspection before shipment
• Continuous improvement based on customer feedback and data analysis

To strengthen our quality control, we have developed a customized MES (Manufacturing Execution System) that integrates every step of the production process. This system provides real-time data on production status, component traceability, and performance metrics, ensuring process transparency. With MES, we can quickly identify and resolve issues, reduce waste, and optimize production efficiency.

• Real-time production monitoring
• Automated quality control checkpoints
• Full traceability from raw materials to finished products
• Detailed production analytics and reporting
• Efficient defect tracking and resolution

Our commitment to quality is reinforced by our compliance with international standards. In addition to ISO 9001, our products are tested and certified to meet industry-specific requirements, including CE, ROHS, and FCC certifications, ensuring compatibility, safety, and environmental responsibility across various applications. This dedication to quality allows us to support the needs of data centers, industrial automation, telecommunications, and other critical industries.

From optical sub-assemblies (OSA) to complete transceivers and network devices and cabling, every product we manufacture and provide undergoes strict quality checks and performance testing. We utilize advanced inspection technologies and stringent testing protocols to ensure our products consistently meet customer expectations.
