Ethernet cable category comparison
Twisted-pair LAN cables are grouped by performance category. The table below provides a practical starting point for project selection.
| Category | Typical conductor | Typical insulation | Maximum supported speed | Bandwidth |
|---|---|---|---|---|
| Cat5e | 0.50 mm / 24AWG copper | HDPE or FEP | 1 Gbps | 100 MHz |
| Cat6 | 0.57 mm / 23AWG copper | HDPE or FEP | Up to 10 Gbps* | 250 MHz |
| Cat6A | 0.57 mm / 23AWG copper | U/UTP: HDPE; shielded: skin-foam-skin PE; FEP options | 10 Gbps | 500 MHz |
| Cat7 | 0.57 mm / 23AWG copper | Skin-foam-skin PE or FEP | 10 Gbps | 600 MHz |
| Cat7A | 0.57 mm / 23AWG copper | Skin-foam-skin PE or FEP | 10 Gbps | 1000 MHz |
| Cat8 | 0.63 mm / 22AWG copper | Skin-foam-skin PE or FEP | 25 / 40 Gbps | 2000 MHz |
*Cat6 can support 10GBASE-T over shorter channel lengths. Cat6A is the normal starting point for 10GBASE-T channels up to 100 metres. Final performance depends on the complete compliant channel.
Start with speed and distance
Choose the category that supports the required data rate across the planned channel length.
Then review PoE and EMI
Power delivery, bundle size and interference affect conductor and shielding decisions.
Finish with pathway requirements
Indoor, riser, plenum and outdoor routes require different jacket and fire-performance choices.
Common nomenclature for cable construction
ISO/IEC designations separate the overall cable shield from shielding around each twisted pair. U means unshielded, F means foil, S means braid or screen, and TP means twisted pair.
| Common abbreviations | ISO/IEC 11801 designation | Overall cable shielding | Pair shielding |
|---|---|---|---|
| UTP, TP | U/UTP | None | None |
| STP, ScTP, PiMF | U/FTP | None | Foil |
| FTP, STP, ScTP | F/UTP | Foil | None |
| STP, ScTP | S/UTP | Braid | None |
| SFTP, S-FTP, STP | SF/UTP | Braid and foil | None |
| FFTP, STP | F/FTP | Foil | Foil |
| SSTP, SFTP, STP, PiMF | S/FTP | Braid | Foil |
| SSTP, SFTP, STP | SF/FTP | Braid and foil | Foil |
Unshielded twisted pair
No overall shield and no individual pair shield. It is widely used for Cat5e and Cat6 office networks where the EMI environment and grounding strategy support unshielded cabling.
Overall foil shield
Four unshielded pairs are wrapped in an overall foil screen. This construction improves EMI and crosstalk control while remaining simpler than individually shielded-pair designs.
Braid plus pair foil
Each pair is foil-shielded and the cable core has an overall braid. It provides high shielding effectiveness and is commonly used for Cat7, Cat7A and Cat8 constructions.
Standard and customized cable range
ZION supports common global constructions, CMP-rated options and project-specific designs. Availability, certification scope and minimum order quantity should be confirmed against the requested construction.

Reference standards and production flow
Applicable production and fire-performance references may include UL 444, UL 1581, UL 1666, IEC 60332-1, IEC 60332-3-24 and EN 50399. The exact standard set depends on cable marking, jacket rating and target market.
Ethernet cable testing and quality control
Reference test standards include ISO/IEC 11801 and ANSI/TIA-568-C.2. Testing may evaluate insertion loss, return loss, crosstalk, attenuation and other electrical performance parameters.
Link and channel verification
Fluke DSX-series and DTX equipment can be used to verify installed links or channels. Link testing evaluates the installed permanent link, while channel testing includes applicable connection components and patch cords.
Cable-length performance testing
Network analyzers can evaluate cable at controlled lengths such as 100 m and 305 m, supporting factory inspection of transmission parameters before packing.
Packing formats for network cable orders
Select packing according to cable length, conductor size, cable outside diameter, installation method and handling requirements.
Copper cabling infrastructure
Complete the network cable channel with compatible patching, termination, outlet and installation accessories from HELLOSIGNAL.
Cabinet and racks
Organize patch panels, switches, cable management and related network equipment with rack and cabinet options for equipment rooms and distributed installations.

Frequently asked questions
What is the practical difference between Cat6 and Cat6A?
Cat6 supports 250 MHz and can support 10 Gigabit Ethernet over shorter channel lengths. Cat6A supports 500 MHz and is designed for 10GBASE-T channels up to 100 metres when installed as a compliant system.
When should a shielded Ethernet cable be selected?
Shielded cable is commonly selected for high-EMI routes, industrial environments and performance-sensitive links. The bonding and grounding design should be reviewed with the complete cabling system.
Which jacket should be used for outdoor or plenum installation?
Outdoor pathways normally require a UV- and moisture-resistant construction such as PE, while applicable air-handling spaces may require CMP-rated cable. The final choice must follow project documents and local code.
Can ZION customize cable construction and packing?
Available project options include messenger wire, double jackets, armor, fire-performance constructions, cable marking, pull boxes, plastic spools and wooden spools, subject to technical and commercial confirmation.
