Heizka’s CAT7A cable is the highest-performance copper solution in our portfolio — an individually shielded twisted-pair (S/FTP) design qualified to Class FA, 1000MHz. Each of the four pairs is wrapped in its own foil shield, then enclosed by an overall braid, giving outstanding isolation against alien crosstalk and external electromagnetic interference. With 23 AWG solid bare copper conductors and a skin-foam-skin insulation design, it delivers stable 10GBASE-T performance with significant headroom for next-generation short-reach applications and heavy-duty Power over Ethernet (PoE/PoE+/PoE++).
This makes it the preferred choice for high-density data centers, financial trading floors, hospitals, and industrial environments where electromagnetic noise or future bandwidth growth are concerns. It is available with PE, CM, PVC, or LSZH jackets to match indoor, riser, or fire-safety requirements. Every reel is manufactured and tested to ISO/IEC 11801, TIA 568C.2, and IEC 61156 standards, and backed by Heizka’s multi-year warranty for long-term field performance.

Frequently Asked Questions
Yes. The individually shielded pairs and 23 AWG solid bare copper conductors let this cable safely carry IEEE 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++) power alongside high-speed data.
CAT7A (Class FA) is qualified to 1000MHz versus CAT6A’s 500MHz, and every pair is individually foil-shielded (S/FTP) plus wrapped in an overall braid, giving much better isolation against alien crosstalk and external EMI. Choose CAT7A for high-EMI environments, maximum bandwidth headroom, or dense data-center risers; choose CAT6A when 10GBASE-T over unshielded cable is sufficient and full-shield grounding isn’t practical.
Yes. Because CAT7A is a shielded (S/FTP) cable, the shield must be properly bonded and grounded at both ends through shielded patch panels and connectors for the shielding to be effective — improper grounding can create ground loops and actually degrade performance.
LSZH (Low Smoke Zero Halogen) jacketing limits flame spread and emits minimal toxic smoke and no halogen gases when burned. It’s typically required in high-occupancy buildings such as hospitals, data centers, and transit stations, per IEC 60332-1-2 / 60332-3.
Standard packaging is 305m per pull-box for all four jacket/color variants (HEC7ASF3PE, HEC7ASF1CM, HEC7ASF1PC, HEC7ASF5LZ).
