What is Cat7 cable?

Category 7 Cat7 cable, which can achieve higher transmission performance than previous Ethernet standards. This twisted pair is fully shielded, so it can also be called shielded twisted pair (SSTP) or shielded twisted pair (SFTP) wiring. Alien crosstalk interference is completely eliminated, improving noise immunity. The seven-category Cat7 standard was established by the International Organization for Standardization (ISO) in 2002 and is also known as Class F cabling, which has a longer lifespan than Cat5e and Cat6 cables, providing users with a higher overall return on investment.

Category 7 cabling is the latest cable standard for Ethernet and other interconnect technologies, developed with stringent crosstalk and electromagnetic interference protection specifications. Category 7 cable features four individually shielded pairs and overall cable shielding, providing a copper solution for 100m 10 Gigabit Ethernet transmission.

Application of Cat7 cable in data center: Its cabling standard is mainly suitable for the backbone connection between servers in the data center, and can provide high-speed interconnection for data transmission in the network.

The introduction of Category 7 cables will inevitably have an impact on fiber optic cabling, and Cat7 cables are an alternative to using optical fibers in data centers. In terms of investment, the overall cost of copper cabling equipment is lower than equipment supporting fiber optic cabling. In addition, copper wire is easy to operate and more reliable in wiring, and fiber optic cable is relatively fragile and easily damaged.

Is there a big difference between Cat7 and Cat5e/6 in practical application? Cat7 cables support higher frequency signals than Cat5e and Cat6, and allow for the transmission of larger volumes of information. Cat7 cable is more protective and reliable for the signal transmitted by the cable, which helps to reduce the impact of crosstalk and electromagnetic interference.

The use of Cat7 has not yet been widely adopted, and in terms of short-term network form, Cat5e and Cat6 solutions can meet the bandwidth needs of today's data centers, networks and end users. But as technology advances and demand increases, Cat7 cables will be the future of data center and desktop connectivity.
