AI-Powered supplier vetting

SummaryThe supplier is explicitly identified as a professional technical supplier offering 3D software design and broad customization services. Its stated business scope covers software, electronic products and equipment, optical communication products, fiber and cable, rubber and plastic products, and related import/export activities. However, operational controls appear limited: finished products are checked by packing staff, only one quality-control employee and one R&D engineer are reported, and no quality-control test equipment was found. There are no written corrective-action or complaint-handling procedures, no raw-material traceability, and no warehouse-control evidence. Financial records are referenced for 2021–2023, but no substantive financial results are provided. No certification, customer case, or environmental and fire-compliance evidence is available in the provided slices.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its listed scope includes software and auxiliary equipment, electronic products and equipment, optical communication equipment, optical fiber and cable, and related product sales and technology import/export activities.

After-Sales capabilityThe supplier has no written procedures or records for handling customer complaints, and its service-capability assessment procedure also lacks written procedures or followed records. These findings indicate weak documented after-sales/service processes.

R&D capabilityThe supplier is identified as having R&D capability and providing 3D software design services, with one R&D engineer responsible for producing samples according to customer requirements. However, no SDK is available, and the limited staffing evidence does not establish broader innovation strength.

Production capacityProduction and fulfillment evidence is limited: finished products are checked by packing staff, quality-control staffing is one person, no quality-control test equipment was found, and the supplier reports no in-stock capacity. Peak- and off-season lead times are each stated as one month, but the overall evidence does not demonstrate robust production capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. Its R&D engineer is also responsible for providing samples according to customer requirements, directly supporting customized development.

Product Q&A

Q:What is the available wavelength range?

The coupler supports special wavelengths ranging from 445 nm to 2100 nm, including options like 488, 532, 635, 780, 830, 980, 1064, 1700, and 2000 nm.

Q:What are the maximum optical power limits?

The maximum continuous wave optical power is 4W. For visible wavelengths, the limit is 50 mW when only one connector is added.

Q:Can the coupling ratio be customized?

Yes, the coupling ratio is available from 1/99 to 50/50, including options like 2/98, 5/95, 10/90, 20/80, 30/70, and 40/60.

Q:What connector types are supported?

Supported connector types include FC/UPC, FC/APC, SC/UPC, and SC/APC. None (N) or specified types (S) are also available.

Q:What fiber types are available?

Available fiber types include Nufern 460-HP, Nufern 630-HP, Corning HI 780C, Corning HI 1060, Corning HI 1060 Flex, Corning SMF-28, and Nufern SM 1950.
