Ethernet cables can be summarized and translated into English as follows:
Main Trunk Wiring Due to the length limitation of 30 meters for both Class I and II channels of CAT8 Ethernet cables, they are primarily used in data centers without the need for traditional 100-meter complete wiring. Backbone and access point wiring may also become common in regular enterprise buildings. Many buildings have backbones shorter than 30 meters, and many indoor access points do not require long cables. It is foreseeable that the speed of access points will exceed 10Gbit/s in the future, necessitating better cabling than CAT6A.
| Type | Cat 8 | Cat 7 | Cat 6A | Cat 6 | Cat 5e |
| Rate | 40Gbps | 10Gbps | 10Gbps | 1000Mbps | 100Mbps |
| Bandwidth | 2000MHz | 600MHz | 500MHz | 250MHz | 100MHz |
| Max Distance | 30 meters | 100 meters | 100 meters | 100 meters | 100 meters |
| Conductors | 4 pairs | 4 pairs | 4 pairs | 4 pairs | 4 pairs |
| Cable Type | Shielded | Shielded | Shielded/Unshielded | Shielded/Unshielded | Shielded/Unshielded |
| Application | Industrial Equipment & Data Centers | High-Speed Broadband & Data Centers | Large Enterprises & High-Speed Applications | Large Enterprises & High-Speed Applications | Small Offices & Home Use |
Home Applications For homes, certain applications may also catalyze the need for high-speed structured cabling. The typical length of home wiring is roughly the same as that in data centers, making CAT8 Ethernet cables a potential future-proof choice for home wiring. Especially in terms of sustainability, home wiring is long-term or permanent, and pre-embedded installation of CAT8 cables is an excellent choice.
Ethernet Speeds The most common application is 40GBase-T. The IEEE has a relatively new initiative, 25GBase-T Ethernet speed. It turns out that 25GBase-T is finding more supporters than 40GBase-T. On the one hand, the cost is lower because the transceivers for 25GBase-T are less expensive to produce than those for 40GBbase-T. On the other hand, in terms of speed aggregation, the next higher speed in data centers is 100Gbit/s Ethernet, usually on fiber optic cabling. Aggregating 4x 25Gbit/s into a 100Gbit/s line is easier than aggregating 40Gbit/s lines into a 100Gbit/s line.
Market Prospects Currently, CAT8 Ethernet cables have begun to receive significant attention from major operators and manufacturers. They provide a high-cost-performance transmission medium for network construction. With the rapid changes in the network information era, they have a promising market outlook.
Public Demand CAT8 Ethernet cables can meet the public's demand for efficient and stable signal transmission. As the general public's requirements for transmission performance increase, CAT8 cables will gradually become the main equipment wiring for short-distance transmission.
