AI-Powered supplier vetting

SummaryThe supplier is a limited company offering fiber optic cable, optical fiber, and related cable products. It demonstrates documented quality and service procedures, ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, and employs 10 R&D engineers and 25 quality-control staff. Customization, ODM, and OEM services are available, supported by multiple production lines and documented design records. However, the supplier reported no new products in the past year, no 3D design service, no SDK, no overseas warehouse, showroom, agent, or branch, and no factory environmental impact assessment report. Customer-case evidence is limited to OEM work for well-known brands; no Fortune 500 cooperation was reported.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications. Product compliance certification is recorded only as “Others,” and the supplier lacks a factory environmental impact assessment report, so product-specific and environmental documentation is incomplete.

After-Sales capabilityThe supplier has 10 R&D engineers whose responsibilities include production and after-sales service, plus written and followed procedures for complaints, corrective/preventive actions, and service-capability assessment. It offers lead times within 15 working days in both peak and off-season, but has no overseas warehouse, showroom, agent, or branch.

Production capacityProduction resources include fiber drawing, screening and rewinding, coloring and rewinding, parallel tape, optical fiber extrusion, cable production, and sheath production lines. Finished-product inspection instructions are available and uniformly followed, supported by 25 quality-control staff and two listed test-equipment units.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, flexible customization, ODM, and OEM services. These capabilities are supported by 10 R&D engineers and documented design-process records, although 3D software design and SDK services are unavailable.
