About Guangzhou Dtech Electronics Technology Co., Ltd. - Electronic Components Supplier in China

Guangzhou Dtech Electronics Technology Co., Ltd. operates from Guangzhou, China and currently lists 24 active products across its catalogue. The catalogue is organised under categories that include Agriculture, Wires & Cables, Computer Hardware & Peripherals, Converters & Switches, and Electric Components. The electronic‑hardware segment contains HDMI extenders up to 120 m over IP, multiple HDMI splitters supporting 4K×2K resolution, BNC and SDI splitters, VGA splitters and matrix switches, as well as KVM switchers ranging from 4 × 1 to 8 × 1 with optional app control. Cable offerings include HDMI 2.0 copper‑core cables, fiber HDMI cables, USB 2.0 extenders, Type‑C to VGA converters, and industrial RS232 to RS485 converters. All items are listed with product names that identify their functional class and typical technical parameters such as transmission distance, resolution support, or connector type.

The product set reflects standard video‑signal distribution equipment that is classified under HS chapter 85, for example HS 8544 for video display devices and HS 8543 for electronic integrated circuits. No additional HS codes are provided in the catalogue, so buyers should confirm the exact code during customs filing. The supplier’s trust tier is listed as “harbor”, indicating a moderate level of verification on the platform. The catalogue does not disclose any specific certifications held by the supplier, therefore buyers are advised to request compliance documents such as CE, RoHS, or FCC test reports where applicable.

Product Range and Specialties of Guangzhou Dtech Electronics Technology Co., Ltd.

The listed products cover three main functional families: signal extension (HDMI and USB extenders up to 120 m over Cat5e/6 or fiber), signal distribution (HDMI, VGA, BNC, SDI splitters ranging from 1 × 2 to 1 × 16 outputs and matrix switches with audio embedding), and control interfaces (KVM switchers, RS232‑to‑RS485 converters, Type‑C to VGA+PD adapters). Typical specifications for HDMI extenders include support for HDMI 2.0, 4K@60 Hz, HDCP 2.2, and Ethernet‑based PoE power where noted. Splitters usually retain full 4K resolution on each output and may incorporate EDID management. Cables are offered with pure copper conductors, AWG 24 for HDMI, and shielding to meet EMI standards for video applications.

In the broader industry, HDMI distribution gear is commonly graded by resolution (1080p, 4K, 8K), distance capability (30 m, 60 m, 120 m), and compliance with HDMI 2.0/2.1 standards. VGA products are rated by bandwidth (250 MHz, 500 MHz) and support for analog video over 15‑pin D‑sub connectors. RS232‑to‑RS485 converters are evaluated on baud rate support (up to 115 200 bps) and isolation voltage. Buyers typically request CE, RoHS, and FCC test reports, as well as third‑party compliance certificates such as UL for safety when the equipment is destined for North American or European markets.

Trade and Export Information - Guangzhou Dtech Electronics Technology Co., Ltd.

China ranks among the top global exporters of video‑distribution hardware and cable assemblies, with major outbound flows to the United States, Europe, and Southeast Asian manufacturing hubs. Products such as HDMI extenders, splitters and KVM switches fall under HS chapter 85 and are usually shipped in standard 20‑ft or 40‑ft containers, packed in anti‑static foam and double‑wall cartons to protect against mechanical shock. Common Incoterms used by Chinese electronic component exporters include FOB Guangzhou Port and CIF destination ports in Europe or North America. Importers often require CE marking for EU markets, RoHS compliance for hazardous substance limits, and FCC Part 15 certification for electromagnetic compatibility in the United States. Export documentation typically includes a commercial invoice, packing list, certificate of origin, and any requested test reports.

Sourcing from Guangzhou Dtech Electronics Technology Co., Ltd. - Buyer Guidance

When evaluating Guangzhou Dtech Electronics Technology Co., Ltd. as a source, buyers should request detailed datasheets that list supported HDMI version, maximum cable length, power consumption (for PoE extenders), and shielding class for each product. Third‑party test reports confirming HDMI compliance, video latency, and EMI performance help verify that the equipment meets industry standards. Because the supplier’s catalogue does not list specific certifications, buyers are advised to ask for CE, RoHS, FCC or UL certificates before finalising a purchase. Standard minimum order quantities for electronic distribution kits range from 50 to 200 units, and lead times for assembled cable sets are typically 15 - 30 days after order confirmation, subject to component availability.

What video resolutions are supported by the HDMI splitters listed in the catalogue?

The splitters are described as 4K*2K models, which indicates support for HDMI 2.0 video up to 3840 × 2160 pixels at 60 Hz. Buyers should verify HDCP 2.2 compliance for protected content.

Are the HDMI extenders capable of delivering power over Ethernet (PoE)?

One product is named “POE HDMI Extender over IP 120m”, which suggests PoE support for both data and power. Confirmation of PoE class and power budget should be obtained from the supplier.

Which certifications should a buyer request for these video distribution products?

Typical certifications include CE for EU market entry, RoHS for restriction of hazardous substances, FCC Part 15 for US electromagnetic compatibility, and UL safety listing where applicable.

What is the typical HS code range for the listed HDMI and VGA accessories?

Video transmission equipment and related accessories are generally classified under HS chapter 85, such as HS 8544 for video display devices and HS 8543 for electronic integrated circuits. Exact codes depend on product specifics and should be confirmed during customs filing.

What are common packaging practices for HDMI cables and extenders exported from China?

Exporters usually pack cables in anti‑static poly bags, then place them in double‑wall cartons with cushioning. Larger units like extenders or matrix switches are often palletised with shrink‑wrap for container loading.

What lead time and MOQ are typical for the HDMI and VGA cable products?

Standard lead times for cable assemblies from Chinese manufacturers range from 15 to 30 days after order confirmation. Minimum order quantities are commonly set between 50 and 200 units, depending on length and connector configuration.

How can a buyer verify the quality of the HDMI fiber cable (type D‑A 444 100m)?

Buyers should request an optical loss measurement (dB/km) report, bend‑radius specifications, and compliance with IEC 60793‑1‑19 for multimode fiber. A sample test for signal integrity at 4K resolution is advisable before bulk purchase.

Is there support for custom cable lengths or connector configurations?

Many Chinese cable manufacturers offer OEM services for custom lengths and connector types. The buyer should inquire about tooling fees, minimum order quantities for custom runs, and lead time extensions associated with bespoke specifications.
