Solid copper vs. CCA - which is better?

Solid copper - lower resistance, longer life. CCA is cheaper but runs hot; avoid for PoE or long runs.

Flat vs. round cable - any difference?

Flat is easier to route but less noise-resistant. Round has proper twisted pairs for stable performance - better for in-wall wiring.

Outdoor vs. indoor cable?

Outdoor has waterproof, UV-resistant PE jacket; indoor uses PVC. Outdoor lasts longer outside but is stiffer.

Does one RJ45 connector fit all cables?

Yes, but thicker Cat6/7/8 need special 3-piece connectors for secure crimping, or you may lose speed.

Which cable should I buy for home use?

Cat6 (10 Gbps @ 55 m) is plenty. For new wiring, go with Cat6a or Cat7 for future-proofing.

AI-Powered supplier vetting

SummaryFoshan Yangyang Optoelectronic Technology Co., Ltd. is identified as a Chinese trading company and manufacturer/factory operating in Guangdong. The supplier reports broad customization and ODM capabilities, new product development within the past year, and OEM service for well-known brands. Manufacturing resources include eight production lines, six to ten R&D engineers, and six to ten quality-control staff. Export activity is established, with exports representing 51%–70% of total sales and two years of export experience. CE and RoHS certifications are reported. Service processes show documented corrective/preventive actions and complaint handling, but no written service assessment procedure or approved supplier list. Financial information is limited to referenced years without substantive performance figures. No specific customer names or verifiable customer cases are provided.

Supplier typeThe supplier is classified as both a trading company and manufacturer/factory, with a combined company type. It is registered in China and operates in Guangdong, indicating a hybrid sourcing and manufacturing structure.

CertificationsThe supplier reports holding CE and RoHS product certifications. These certifications provide explicit evidence of conformity claims, although the slices do not specify product scope, certificate numbers, or validity dates.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and for handling customer complaints. However, its service-capability assessment has no written procedures or followed records, and it has no approved suppliers list, so the evidence supports specific service processes but not a fully mature service system.

R&D capabilityThe supplier reports new products within the past year, ODM availability, six to ten years of total R&D engineer experience, and customization from samples or designs. It also reports no available SDK, but this is a specific limitation rather than evidence that overall innovation capability is deficient.

Production capacityThe supplier operates eight production lines and reports six to ten quality-control staff, providing explicit evidence of established manufacturing resources. However, it does not continuously reconcile quantities for every batch or mass production, indicating a documented production-control weakness.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and design-service information.
