Complete Guide to SFTP Cable

The use of proper cables plays a crucial role in ensuring data integrity and protection. In this comprehensive guide, we will explore the world of SFTP cables, also known as Shielded Foiled Twisted Pair cables, and unravel the mysteries behind their functionality, applications, advantages, and where to find them.

What is an SFTP Cable?

SFTP cable is a type of twisted pair cable that provides enhanced protection against electromagnetic interference (EMI) and radio frequency interference (RFI). It consists of multiple twisted pairs of copper conductors, each pair individually shielded with a metallic foil, and an overall braided shield surrounding all the pairs. This layered shielding design sets SFTP cables apart from other cable types and makes them highly effective in maintaining signal quality and integrity.

How Does SFTP Cable Work?

SFTP cables utilize a combination of shielding mechanisms to mitigate interference. The individual pair shielding prevents crosstalk between adjacent pairs, while the overall braided shield acts as a barrier against external interference. This dual-shielding design significantly reduces signal degradation and ensures reliable data transmission, even in environments with high levels of electromagnetic noise.

What Is an SFTP Cable Used for?

SFTP cables are widely used in various applications that demand secure and high-speed data transfer. Some common applications include:

●Local Area Networks (LANs)

SFTP cables are commonly employed in LAN installations where data security and reliability are critical, such as government organizations, financial institutions, and healthcare facilities.

●Industrial Environments

SFTP cables find utility in industrial settings prone to electrical noise, such as factories and manufacturing plants, where they help maintain uninterrupted communication between control systems and equipment.

●Telecommunication Systems

SFTP cables are used in telecommunications infrastructure, such as backbone cabling, to ensure stable and interference-free transmission of voice, data, and video signals.

●Data Centers

SFTP cables are employed for interconnecting servers, switches, and storage systems within data centers, ensuring efficient and secure data transfer.

●CCTV and Security Systems

SFTP cables provide reliable connections for surveillance cameras, enabling the transmission of high-quality video feeds without interference.

What Are the Advantages of Using SFTP Cables?

SFTP cables offer several advantages over other cable types, making them an ideal choice for critical applications:
Enhanced Data Security: The multiple layers of shielding protect against external electromagnetic interference, preventing data loss or corruption, and reducing the risk of unauthorized access.

●Improved Signal Quality

The individual pair shielding minimizes crosstalk, ensuring high-quality signal transmission, even over long distances.

●Resistance to Noise

The overall braided shield provides excellent resistance to electromagnetic and radio frequency interference, ensuring reliable data transfer in noisy environments.


SFTP cables meet stringent industry standards and are designed to support high-speed data rates, making them suitable for future network upgrades and advancements in technology.

Where Can I Purchase SFTP Cables?

SFTP cables are available from various reputable suppliers and retailers, both online and offline. VRGHT is one of the well-known and trusted manufacturers in China. VRGHT has an independent production line and a stable supply chain, so you can always trust the SFTP cables from VRGHT.
