Cat6A FTP Shielded Twisted Pair Cable. AL-foil shield, tinned-copper drain wire, blue PVC jacket, O.D. 7.2mm, 23AWG solid 4N OFC, cross-filler spline, -20 to +70C. 1Gbps/250MHz. From LBS Catalog 2026.

Cat6A FTP for Shielded 10Gbps Runs

This Cat6A FTP cable adds an aluminium-foil shield and tinned-copper drain wire over the 23AWG solid 4N OFC Cat6A core. The foil shield provides protection against external interference while the drain wire gives a clean termination point for the shield. Cat6A FTP is a practical middle option for 10Gbps horizontal runs where the cable passes near power feeders or lighting circuits but a full double-shielded SFTP cable is not required.

Compare the shielding levels in the LBS Cat6A family: Cat6A UTP (unshielded), this FTP (foil), and Cat6A 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.

Applications / 应用

10Gbps data backbones, AV-over-IP (Dante, AVB, NDI), building network risers, PoE+ cameras and general commercial network installation where foil shielding is specified.

Cat6A FTP FAQ

Q: What is the difference between Cat6A FTP and Cat6A SFTP?
A: FTP uses one aluminium-foil shield over the core. SFTP uses foil plus an overall tinned-copper braid for double shielding, giving more noise immunity in electrically noisy environments.

Q: Does Cat6A FTP support 10Gbps?
A: The LBS 2026 catalog lists this foil-shielded Cat6A construction as Gigabit Ethernet (1000 Mbps / 1 Gbps) with transmission bandwidth up to 250 MHz. The shield type affects noise immunity, not the Gigabit rating. Where a 10 Gbps / 500 MHz backbone is specified, LBS supplies the Cat6A S/FTP 10G construction (LBS6ASSTP-C6A).

Q: Can the drain wire be terminated in standard RJ45?
A: The drain wire is intended to be connected to the shield at the patch panel or equipment end. Your installer should follow the connector manufacturer’s shielded termination instructions.

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.

AV over IP Network Cable Selection

In an AV-over-IP project — Dante audio, NDI video, SDVoE or control networks — the Cat6A FTP construction is often the practical choice for links that run through equipment racks, cable trays and corridors where some electrical noise exists but a full double-shielded cable is not required. Three selection rules apply:

• Shielding level follows the environment. Clean dedicated AV network runs can use Cat6A UTP; runs near dimmers, lighting racks or power feeders should use at least FTP; stage floors, touring racks and high-EMI locations should use Cat6A SFTP.
• Category follows the protocol. Gigabit audio control systems run comfortably on Cat6A at 250 MHz; video-heavy systems (4K over NDI or SDVoE) benefit from the 10 Gbps / 500 MHz Cat6A S/FTP backbone.
• Keep one construction per link. Mixing UTP and FTP sections on the same run creates grounding and performance questions — standardise the family on one shielding level per zone.

The LBS Cat6A family covers all three shielding levels with the same 23 AWG solid OFC core and cross-filler spline: Cat6A UTP, this Cat6A FTP, Cat6A SFTP and the Cat6A S/FTP 10G. For a full AV-over-IP specification walkthrough, see the AV over IP network cable guide.
