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:
| Item / construction | Shielding | Jacket O.D. | Main conductor | Catalogued speed / bandwidth |
|---|---|---|---|---|
| Cat6A UTP (LBSUTP-C6A) Unshielded twisted pair |
None | 6.2 / 6.4 / 7.2 mm | 23 AWG / 0.25 | Gigabit Ethernet (1000 Mbps / 1 Gbps), up to 250 MHz |
| Cat6A FTP (LBSFTP-C6A) Foil shield + tinned-copper drain wire |
AL-foil + drain wire | 7.2 mm | 23 AWG / 0.25 | Gigabit Ethernet (1000 Mbps / 1 Gbps), up to 250 MHz |
| Cat6A SFTP (LBSSFTP-C6A) (this page) AL-foil plus overall tinned-copper braid |
Foil + braid (double) | 7.8 mm | 23 AWG / 0.26 | Gigabit Ethernet (1000 Mbps / 1 Gbps), up to 250 MHz |
| Cat6A S/FTP 10G (LBS6ASSTP-C6A) Individually foil-shielded pairs + overall tinned-copper braid, Foam-PE insulation |
Foil per pair + braid | 8 mm | 23 AWG / 0.26 | 10 Gigabit (10 Gbps), up to 500 MHz |
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.
