SummaryThe supplier is identified as a Shenzhen-based trading company serving fiber and UTP transmission products. It reports CE, FCC, RoHS, CB, and NOM certifications, but no supplier-management-system certification. The supplier has one R&D engineer, documented design-development records, 3D design and broad customization capabilities, and offers ODM and OEM services. Reported production includes Industrial Ethernet Switches, Industrial PoE Switches, HDMI Fiber Extenders, and PoE Injectors, with stated annual capacities for each product. Service processes include written procedures, supplier assessment records, corrective and preventive actions, complaint handling, and an off-season lead time within 15 workdays. It has in-stock capability but no overseas warehouse, showroom, agent, or branch. Quality-assurance status, traceability, and the quantity of quality-control testing equipment are unknown; the stated equipment count is zero. Export markets are broad, and 41%–50% of sales are exports. Financial...
CertificationsThe company description explicitly lists CE, FCC, RoHS, CB, and NOM certifications. However, supplier-management-system certification is recorded as NIL, so the evidence supports product or market certifications but not certified management systems.
After-Sales capabilityTechnology engineers provide technical support for after-sales service, and the supplier reports written service procedures, followed records, corrective and preventive action procedures, complaint-handling procedures, and in-stock capability. The absence of overseas warehouses, showrooms, agents, and branches limits demonstrated local overseas support.
R&D capabilityThe supplier has one R&D engineer, reports new products within the past year, provides 3D software design, maintains design input/output, review, verification, and validation documentation, and offers ODM services. However, it lacks an available SDK and has limited stated R&D staffing.
Production capacityThe supplier reports annual capacities of 200,000 Industrial PoE Switches, 100,000 HDMI Fiber Extenders, 500,000 Industrial Ethernet Switches, and 1,000,000 PoE Injectors, with an off-season lead time within 15 workdays. It also reports 15 qualified service-capability suppliers and documented supplier-management procedures, although its classification as a trade company means direct manufacturing capability is not fully established.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides 3D design services and ODM/OEM services, directly supporting broad customization capability.
