超六类局域网电缆 SFTP

Cat6A SFTP Double Shielded Twisted Pair Cable. AL-foil plus tinned copper braid double shield, blue PVC jacket, O.D. 7.8mm, 23AWG solid 4N OFC, cross-filler spline, -20 to +70C. 1Gbps/250MHz. From LBS Catalog 2026.

Cat6A SFTP for Demanding 10Gbps and AV-over-IP Runs

This Cat6A SFTP cable uses double shielding — aluminium foil plus an overall tinned-copper braid — over the 23AWG solid 4N OFC Cat6A core. The double shield gives the highest noise immunity in the LBS Cat6A family, which makes it the choice for 10Gbps and AV-over-IP runs that share a riser or cable tray with power feeders, dimmer packs, motors or lighting circuits.

Compare the shielding levels in the LBS Cat6A family: Cat6A UTP (unshielded), Cat6A FTP (foil), and this SFTP (foil plus braid). See UTP vs FTP vs SFTP Ethernet Cable for the full comparison, and the LBS6ASSTP-C6A Cat6A S/FTP 10G cable for the double-shielded backbone option with the same construction.

Applications / 应用

10Gbps backbones, AV-over-IP (Dante, AVB, NDI), broadcast and production networks, industrial environments with electrical noise, and any run where the customer wants maximum shielding margin.

Cat6A SFTP FAQ

Q: When should I choose Cat6A SFTP instead of FTP?
A: Choose SFTP when the cable runs in electrically noisy environments — near power feeders, dimmers, motors or high-voltage risers — or when the specification demands double shielding for maximum noise margin.

Q: Does Cat6A SFTP support 10Gbps?
A: The LBS 2026 catalog lists this double-shielded Cat6A construction as Gigabit Ethernet (1000 Mbps / 1 Gbps) with transmission bandwidth up to 250 MHz. The double shield provides the highest noise immunity in the family. Where a 10 Gbps / 500 MHz backbone is specified, LBS supplies the Cat6A S/FTP 10G construction (LBS6ASSTP-C6A).

Q: Can LBS supply Cat6A SFTP in custom lengths?
A: Standard 305 m boxes are available, and custom lengths, jacket printing, colour and packaging can be reviewed as part of an OEM / ODM project — send the requirement through the contact page or WhatsApp.

Cat6A Family Comparison: UTP / FTP / SFTP / S-FTP 10G

Every Cat6A construction in the LBS range shares the same 23 AWG solid 4N OFC conductor and an internal cross-filler spline that keeps the four pairs separated. The buyer choice is the shielding level — and, for the 10G backbone item, the insulation and bandwidth rating. The table uses the values published in the LBS 2026 product catalog, Cat6A series:

All four constructions: blue PVC jacket, applicable temperature -20°C to +70°C. Source: LBS 2026 product catalog, Cat6A series. Confirm the exact SKU and construction for your project before ordering.

Selection rule: pick the lowest shielding level the installation actually needs — UTP for clean dedicated data/AV runs, FTP where the run passes near power feeders or lighting circuits, SFTP on stage floors, touring racks and high-EMI routes, and the Cat6A S/FTP 10G item where a 10 Gbps / 500 MHz backbone is specified. For the shielding comparison in detail, see the UTP vs FTP vs SFTP Ethernet Cable guide.
