CAT7A Cable S/FTP Twisted Pair 

Overview: CAT7A Cable S/FTP (Shielded Foiled Twisted Pair) cable is an advanced network cable standard designed to support high-speed data transmission in demanding applications. It is a shielded cable that offers superior performance and enhanced protection against electromagnetic interference (EMI) and crosstalk, making it ideal for environments with high levels of electrical noise or where high data integrity is critical. The CAT7A standard supports frequencies up to 1000 MHz, surpassing the capabilities of CAT6A and even CAT7, and provides backward compatibility with earlier standards.

Cable Structure: The “S/FTP” designation refers to the shielding configuration of the cable:

• S (Shielded): The cable features an overall shield, usually made of braided copper, to protect the entire cable from external interference.
• F (Foiled): Each individual twisted pair within the cable is wrapped in its own foil shield to reduce internal crosstalk between the pairs.
• TP (Twisted Pair): The cable contains four pairs of twisted copper wires that are used for signal transmission. The twisting of the pairs helps reduce signal degradation over long distances.

Features and Benefits:

1. High Bandwidth: CAT7A supports transmission frequencies up to 1000 MHz, allowing for data rates up to 10 Gbps and beyond, which is suitable for future-proof installations.
2. Superior Shielding: The S/FTP design offers exceptional protection against EMI and crosstalk, making it suitable for industrial and high-interference environments.
3. Longer Cable Runs: With CAT7A cables, the effective distance for high-speed data transmission can extend up to 100 meters at 10 Gbps.
4. Durability and Longevity: CAT7A cables are robust and offer excellent durability, making them a reliable choice for permanent or semi-permanent installations.
5. Backward Compatibility: CAT7A cables are fully compatible with lower categories such as CAT6A, CAT6, and CAT5e, allowing for easy integration into existing networks without requiring upgrades to all network components.

Applications:

• Data centers and server farms
• High-speed LAN (Local Area Network) connections
• High-definition video transmission
• Industrial environments with high EMI
