AI-Powered supplier vetting

SummaryThe supplier operates in optical communication, electronic, network equipment, fiber, cable, and related product sales, with three production lines and stated outputs for connectors and PLC splitters. It exports through agents and self-operated import/export rights, serving markets across multiple regions, and has four years of export experience. Customization is available from samples, designs, and minor or flexible requirements. Service procedures, corrective actions, complaint handling, and ERP-based process management are documented. However, the supplier has no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, no ODM, SDK, 3D design, or recent new-product development capability, and does not provide OEM services for popular brands. The evidence does not establish certifications, financial strength, or customer cases.

Supplier typeThe supplier’s stated business scope covers optical communication equipment, optoelectronic devices, optical fiber, electronic and network equipment, metal products, and wire and cable. It operates three production lines and reports production of connectors and PLC splitters, supporting classification as a manufacturer and supplier in the communications-related product sector.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and customer complaint handling. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service processes but not comprehensive overseas service infrastructure.

R&D capabilityThe supplier has no available SDK, no 3D software design service, no ODM service, and reported no new products in the past year. ERP integration is established, but the sustainable-development and technical-transformation entries are recorded as zero, indicating limited demonstrated innovation capability.

Production capacityThe supplier operates three production lines, reports output for connectors and PLC splitters, has inventory capacity, and states a one-month average lead time in both peak and off-season periods. Capability controls have weaknesses: there is no valid contract with related subcontractors, no continuous batch quantity reconciliation, and no outsourcing SOP.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, and flexible customization. These capabilities are supported by design services, although the supplier does not provide 3D software design or ODM services.

Product Q&A

Q:What is the tensile strength of B3 bare fiber compared to A1 and A2?

All three types, B3, A1, and A2 optical fibers, are designed with a tensile strength of 60N, ensuring robust performance.

Q:What are the packaging specifications per spool of B3 bare fiber?

Each spool of B3 bare fiber is packaged with dimensions of 40*35*30cm and a weight of 4.5KG, ensuring convenient handling and storage.

Q:What are the application scenarios for B3 series optical fibers?

B3 series optical fibers excel in scenarios demanding deployment in compact spaces and conditions requiring extensive bending. They are ideal for high-density data center cabling, invisible optical cables, drone cables, and other unique applications.

Q:Is the 60.4km specification in stock? Are there other specifications?

Certainly, we stock the 60.4km specification, alongside standard options of 40.8km and 50.4km. Additionally, we offer customization for a 100km specification tailored to your specific needs.

Q:What is your monthly production capacity?
