Engineered for extreme data throughput and industrial reliability across enterprise server and visual arrays.
Corexis Memory Technology Co., Ltd. is a professional DDR5 memory and high-frequency hardware manufacturer dedicated to delivering high-performance DRAM solutions and precision cable/interconnect assemblies for global OEM, ODM, and brand customers. Since our establishment in 2016, we have focused on memory technology innovation, advanced packaging, high-speed circuit design, and strict signal-integrity quality management. Our products are widely integrated into desktop PCs, laptops, enterprise servers, industrial computers, embedded automation systems, and high-bandwidth AI applications.
With a state-of-the-art modern manufacturing facility covering 21,800 m², Corexis integrates R&D, SMT assembly, multi-layered high-frequency testing, encapsulation, and advanced quality assurance under one roof. Our experienced engineering team continuously pioneers reliable, high-speed storage and interconnect transmission interfaces that meet stringent international regulatory demands.
Demonstrated operational scale powering high-speed interconnect and semiconductor hardware globally.
As transmission standards evolve, the barrier between chip engineering and cable interconnect manufacturing dissolves. At gigabit thresholds—such as DDR5 memory channels (up to 6400 MT/s) and HDMI 2.1b ultra-high-speed pipelines (up to 48 Gbps)—signal integrity faces identical physical threats: electromagnetic interference (EMI), capacitive crosstalk, and high-frequency attenuation. Corexis addresses these challenges by merging advanced SMT board layout capability, high-frequency FR4/Rogers substrate layering, and premium copper shielding lines into our cable and module manufacturing lines. By keeping processing and interconnect pathways strictly regulated, we guarantee zero packets dropped at terminal hardware.
An authoritative breakdown of bandwidth, processing materials, and protocol standards in industrial AV applications.
HDMI 2.1b relies on Fixed Rate Link (FRL) technology rather than TMDS. This changes how data packages are packets, allowing 48 Gbps pathways over four channels to drive native 8K at 60Hz and 4K at 120Hz resolutions without compression loss.
To eliminate external RF pollution in dense environments, our premium assemblies employ 100% overlap Mylar foil wrapping coupled with high-density tinned copper wire braiding, guaranteeing protection from crosstalk and attenuation.
For installations spanning beyond 7 meters, active optoelectronic chips are integrated into the connector shells. They convert digital electrical signals into light rays, enabling lossless transmissions across lengths up to 100 meters.

Why sourcing from advanced Chinese industrial parks drives structural business advantages.
Sourcing high-performance HDMI components from China provides enterprises with access to an unmatched, localized industrial cluster. The materials required for an HDMI cable—oxygen-free copper (OFC) coils, PVC/TPE outer compounding polymers, high-density metal shields, precision gold-plated terminals, and active chipsets—are sourced within a 50-kilometer radius of our manufacturing plant. This proximity lowers transport costs, minimizes raw material storage requirements, and buffers production timelines against unpredictable logistical delays.
Additionally, our factory integrates SMT and chip-on-board (COB) technologies natively. For Active Optical Cables (AOC) requiring laser-to-fiber alignment, our 128 R&D engineers refine automated optical alignment procedures directly within our cleanroom lines, bypassing third-party sub-contractors and lowering final assembly costs.
To eliminate manual variations in wire stripping, crimping, and soldering, our facility employs automated multi-core soldering lines and precision injection overmolding stations. Each cable assembly goes through continuous automated checks:
Navigating global import regulations, certifications, and tailored design requirements.
Exporting to Europe, North America, and high-barrier markets demands total adherence to global directives. Every product exported by Corexis complies with standard safety frameworks:
We work with enterprise purchasers, system integrators, and international brands to deliver highly customized solutions:
Adapting high-frequency connectivity to specific industrial, healthcare, and enterprise environments.
For smart grid systems and transit control rooms, our active optical HDMI systems deliver 4K feed streams across 50 meters with zero latency, ensuring real-time monitoring and fast decision-making.
Operating rooms require artifact-free visual feeds. Our copper-free optical HDMI lines provide complete immunity against electromagnetic noise from nearby MRI and electrocautery machinery.
Designed for in-wall installation, our plenum-rated active cables link boardrooms with central server cabinets, supporting clear audio-visual feeds without signal degradation.
Technical clarifications on HDMI production, importing, and manufacturing standards.
Passive copper cables rely entirely on the electrical signal strength generated by the source device, typically limiting runs to 5–7 meters before signal drop-off occurs. Active Optical Cables (AOC) utilize optical transceiver chips within the connectors to convert the electrical signal into an optical wave, allowing lossless transmission up to 100 meters without external power injectors.
Our testing team uses state-of-the-art Network Analyzers and digital sampling oscilloscopes. We run Time Domain Reflectometry (TDR) measurements to confirm 100Ω impedance tolerances. We also perform Bit Error Rate (BER) tests and generate eye diagrams under full 48 Gbps data rates to guarantee complete stability prior to packaging.
We manufacture cables utilizing certified LSZH (Low Smoke Zero Halogen) compounds as well as UL-rated CMP (Plenum) and CL2/CL3 jackets. These structures are specifically designed for commercial vertical shafts and ceiling air ducts, limiting hazardous gas emissions during fire hazards.
Yes, we provide customizable conductor diameters ranging from 30 AWG down to 24 AWG, depending on length requirements and mechanical flexibility needs. Larger wire cross-sections minimize voltage drop, ensuring consistent power for the built-in active circuits.
Broadening operational reliability through high-frequency PCB manufacturing, server thermal management, and power modules.
