Data LAN structured cabling
CAT 7 S/FTP Cable is a shielded data LAN cable built for Class F structured cabling, using 23 AWG bare copper conductors, individually foil-screened pairs and an overall tinned copper braid for installations where signal integrity and EMI control matter.
The UPCOM range is available with PVC, HFFR and PE sheath options, so the same CAT 7 shielded LAN cable family can be aligned with indoor building routes, fire-performance targets and project-specific installation conditions.

This CAT 7 S/FTP cable is intended for structured cabling environments that need a more protected copper transmission path than standard unshielded constructions. The combination of pair-level foil shielding and an overall tinned copper braid helps reduce external interference and supports cleaner signal behavior in electrically noisy routes, equipment rooms and dense cable bundles.
On the current UPCOM product data, the cable is presented for Ethernet, Fast Ethernet, Gigabit Ethernet, 10GBase-T and PoE / PoE+ applications, making it relevant for projects that still require robust copper distribution in enterprise, industrial and data-room environments.
The core structure follows the logic expected from a shielded high-performance LAN cable: solid copper conductors, foam-skin insulation, foil around each pair and an overall braid outside the laid-up pairs. That build makes this CAT 7 Ethernet cable a better fit for routes where alien noise, switching equipment, power proximity or dense infrastructure can challenge signal stability.
For technical buyers, the important point is not only category naming but the actual construction stack. Pair screening reduces pair-to-pair disturbance, while the external braid adds another layer of protection and helps the cable behave more predictably in demanding installations.
CAT 7 S/FTP cable is suitable where equipment rooms, backbone transitions, floor distributors and horizontal routes need a more shielded copper medium than lower-category or unshielded options.
In production facilities, utility corridors and machine-adjacent paths, extra shielding can help keep copper links more stable when surrounding electromagnetic conditions are less forgiving.
This CAT 7 shielded LAN cable is also relevant for data-room and cabinet infrastructure where cable density, thermal load and environmental control are managed more tightly than in standard office routes.

| CAT 7 S/FTP HFFR | HFFR | Dca | 69 kg/km |

PVC is typically the practical starting point for standard indoor routes. HFFR is the stronger candidate when you want lower smoke and halogen-free behavior aligned with stricter fire-performance expectations. PE fits projects that need a sheath more aligned with tougher outdoor or environmental exposure conditions.
If Euroclass and sheath selection are part of the specification process, it is worth checking your project’s fire-performance requirements against the broader guidance in the CPR compliant cables guide.

The current UPCOM product data references EIA/TIA-568-C.2, ISO/IEC 11801 2nd edition, IEC 61156-5, EN 50173-1 and EN 50288-4-1. That mix places the cable inside a structured-cabling context that technical teams can align with broader project documentation and tender language.
For many buyers, the real decision is not simply “Which category?” but “Which construction, sheath and compliance package fits this exact route?” That is why this page now ties the CAT 7 S/FTP cable more clearly to sheath selection, shielding logic, application fit and adjacent-category comparison instead of repeating generic Ethernet text.
S/FTP means the cable uses individual foil shielding around each twisted pair plus an overall braided screen. That combination is used to improve shielding performance against electromagnetic interference and internal crosstalk.
The current UPCOM page lists 10GBase-T among the supported applications, together with Ethernet, Fast Ethernet, Gigabit Ethernet and PoE / PoE+ use cases.
PVC is the usual starting point for standard indoor routes, HFFR is the better fit when low-smoke and halogen-free behavior is part of the project requirement, and PE is the more route-specific option for tougher environmental conditions.
If the project brief is already moving beyond a CAT 7-level specification or you want to review a higher-category family before freezing the bill of materials, compare this page with the CAT 7A S/FTP product page.
In practical network planning, CAT 7 S/FTP cable is often considered alongside lower-category systems, but the real benefit comes when the full channel design, shielding approach and termination path are planned coherently.
If your team is comparing CAT 5e, CAT 6, CAT 7 and CAT 7A options, start from route conditions, shielding needs, fire-performance requirements and equipment density rather than category labels alone. That approach leads to a cleaner, more defensible cable selection.
