Category 8 Blue-compiled Network Cables: Core Parameters and Application Guide
Cat8 Blue Braided Ethernet Cable is a high-performance shielded network cable of CAT8 standard. It features a blue braided outer sheath and has a transmission rate of 40Gbps and a bandwidth of 2000MHz. It is specially designed for high-demand scenarios.
I. Core Specifications and Performance
Explanation of standard values for parameter items
The maximum transmission rate is 40Gbps, supporting 40GBASE-T Ethernet, and is downward compatible with 10G/1G/100M standards
The bandwidth of 2000MHz far exceeds that of Category 6 (500MHz), Super Category 6 (500MHz) and Category 7 (600 MHZ).
The structure type is S/FTP (double shielded). Each pair of twisted wires has independent aluminum foil shielding and overall braided shielding, which has extremely strong anti-interference ability
The core specifications of 24AWG/26AWG are mostly high-purity oxygen-free copper conductors, which reduce signal loss
The connector RJ45 (50μm gold-plated) metal shielding housing reduces electromagnetic leakage and enhances stability
The maximum transmission distance is 30 meters, and the standard transmission distance at a rate of 40Gbps
The outer material is woven mesh + PVC/TPE blue woven to enhance durability, while also balancing softness and tensile strength
Ii. Core Advantages of Blue Weaving
Anti-interference capability: The braided shielding layer (usually tin-plated copper mesh) provides more comprehensive electromagnetic protection than ordinary aluminum foil shielding and is suitable for strong interference environments (such as computer rooms, beside industrial equipment).
Enhanced durability: The braided structure strengthens the cable's tensile and bending resistance, extending its service life
Visual recognition: The blue appearance makes it easy to quickly distinguish cables of different uses in the wiring system, improving management efficiency
Heat dissipation performance: The braided structure has better heat dissipation than solid sheaths and is suitable for long-term high-load operation
Iii. Typical Application Scenarios
Data center/server room: High-density server connection, storage area network (SAN), 40G switch interconnection
E-sports and gaming equipment: Professional e-sports consoles, gaming routers, high-speed NAS devices, ensuring low-latency and stable transmission
Industrial automation: PLC control systems, industrial robots, machine vision equipment, resistant to electromagnetic interference in factory environments
High-end home network: 8K video transmission, VR/AR devices, smart home hub connection
Business office: multimedia conference rooms, video conferencing systems, high-speed printer clusters
Iv. Key Points and Precautions for Selection
Certification standards: Select products that comply with ISO/IEC 11801 and ANSI/TIA-568.2-D standards to ensure performance meets the standards
Shielding integrity: Check whether the connector is equipped with a metal shielding housing and whether the shielding layers at both ends of the cable are reliably grounded
Core quality: Prioritize high-purity oxygen-free copper (above 99.95%) conductors to avoid the impact of copper-clad aluminum materials on transmission
Length selection: It is recommended not to exceed 30 meters at a speed of 40Gbps. If it exceeds this limit, the speed may drop to 25Gbps
Compatibility: Ensure that the device supports the CAT8 standard or is backward compatible with CAT6A/CAT7 devices
Brand selection: We recommend well-known brands such as UGREEN, Akihabara, and AMP to avoid substandard performance caused by inferior products
V. Comparison with Other Types of network Cables
Network cable category, maximum bandwidth, maximum rate, shielding type, typical uses
CAT5e 100 MHZ 1Gbps UTP is a basic network for ordinary homes and offices
CAT6 250MHz 10Gbps(≤55m) UTP/STP home gigabit, small and medium-sized enterprise network
CAT6A 500MHz 10Gbps(≤100m) UTP/STP high-definition video, enterprise gigabit backbone
CAT7 600MHz 10Gbps(≤100m) S/FTP data center, medical equipment
CAT8 2000MHz 40Gbps(≤30m) S/FTP 40G network, high-density computing environment
Summary
Category 8 blue braided network cables are currently the top solution for copper cable Ethernet. The blue braided design not only enhances the appearance recognition but also improves the anti-interference ability and durability. It is suitable for professional scenarios with extremely high requirements for network speed and stability, and also provides a reliable guarantee for future network upgrades. When making a purchase, one should pay close attention to the certification standards, shielding quality and core material to ensure that the performance meets expectations.
