Cat 6A Armored Cable for Mechanically Protected 10 Gigabit Ethernet Networks

Cat 6A Armored Cable combines Category 6A Ethernet performance with additional steel mechanical protection for industrial, infrastructure and physically demanding network routes. ETK Kablo manufactures armored Cat 6A cables with Steel Wire Armor (SWA) or Steel Wire Braid (SWB) and with U/UTP, U/FTP or S/FTP electrical architectures.

The current ETK Kablo armored Cat 6A portfolio provides transmission performance through 500 MHz for 10GBASE-T networks. These constructions use solid copper conductors, polyethylene insulation, halogen-free inner and outer jackets and either SWA or SWB mechanical protection. Depending on the selected product, the Ethernet core can remain unshielded or include individual pair foils and an overall electromagnetic screen.

Mechanical armor and electromagnetic shielding perform different functions. SWA and SWB protect the cable mechanically, while U/UTP, U/FTP and S/FTP describe how the Ethernet core manages electromagnetic interference. Project engineers should specify these requirements separately.

What Is Cat 6A Armored Cable?

A Cat 6A armored cable is a Category 6A balanced copper Ethernet cable that includes a steel protection layer around the network cable core.

The steel layer adds mechanical protection for fixed installations where a conventional Ethernet cable could face greater physical exposure.

ETK Kablo currently uses two armored constructions:

• Steel Wire Armor (SWA)
• Steel Wire Braid (SWB)

Both mechanical families support Cat 6A transmission through 500 MHz and can form part of 10 Gigabit Ethernet systems when the complete installed channel meets the applicable requirements.

ETK Kablo Cat 6A Armored Cable Range

Mechanical Protection	Current Ethernet Architectures	Current Jacket System
Steel Wire Braid (SWB)	U/UTP, U/FTP, S/FTP	LSOH inner jacket + SWB + LSOH outer jacket
Steel Wire Armor (SWA)	U/UTP, U/FTP, S/FTP	LSOH inner jacket + SWA + LSOH outer jacket

The current portfolio therefore allows buyers to select the required mechanical protection and electromagnetic-screening architecture independently.

Steel Wire Armored Cat 6A Cable

Steel Wire Armored Cat 6A Cable places a steel wire armor layer around the inner-jacketed Ethernet cable core.

In the current ETK Kablo construction, the Ethernet core receives a UV-resistant halogen-free inner jacket. Steel wire armor then surrounds the inner cable, followed by a UV-resistant halogen-free outer jacket.

SWA primarily provides mechanical protection. It should not be confused with Al/PET foil or tinned copper braid used for electromagnetic shielding inside screened Ethernet constructions.

The current SWA family contains U/UTP, U/FTP and S/FTP Cat 6A versions.

Steel Wire Braided Cat 6A Cable

Steel Wire Braided Cat 6A Cable uses braided steel wire around the inner-jacketed Ethernet cable core.

The current ETK Kablo construction places the steel wire braid between UV-resistant halogen-free inner and outer jackets.

SWB provides mechanical reinforcement around the network cable. It should not be confused with the tinned copper braid used as the electromagnetic overall screen in an S/FTP construction.

The current SWB family also contains U/UTP, U/FTP and S/FTP Cat 6A versions.

SWA vs SWB Cat 6A Cable

Feature	SWA	SWB
Full Name	Steel Wire Armor	Steel Wire Braid
Construction Principle	Steel wire armor layer	Braided steel-wire layer
Main Function	Mechanical protection	Mechanical reinforcement
Current Cat 6A Core Options	U/UTP, U/FTP, S/FTP	U/UTP, U/FTP, S/FTP
Current Jacket System	LSOH / SWA / LSOH	LSOH / SWB / LSOH

The correct mechanical construction should follow the cable route and project requirements. One armor type should not automatically be treated as universally preferable.

Mechanical Armor vs Electromagnetic Shielding

Cat 6A armored cables can contain several metallic elements, but these components serve different engineering purposes.

Component	Main Purpose
Individual Al/PET Pair Foils	Electromagnetic screening around individual twisted pairs
Tinned Copper Braid	Overall electromagnetic screening in S/FTP constructions
Tinned Copper Earthing Wire	Supports continuity and termination of applicable screen systems
Steel Wire Braid	Mechanical reinforcement
Steel Wire Armor	Mechanical protection

This distinction matters during procurement. A mechanically armored cable can still have an electrically unshielded U/UTP core. Conversely, an S/FTP cable can contain extensive electromagnetic screening without steel mechanical armor.

Cat 6A U/UTP Armored Cable

Cat 6A U/UTP Armored Cable combines an electrically unshielded Category 6A Ethernet core with SWA or SWB mechanical protection.

The current ETK Kablo U/UTP armored construction uses solid copper conductors, solid polyethylene insulation, four twisted pairs and a star-shaped separator.

A halogen-free inner jacket surrounds the data-cable core before the steel mechanical layer. A halogen-free outer jacket then completes the construction.

U/UTP contains no dedicated foil or copper-braid electromagnetic screen around the Ethernet pairs.

Cat 6A U/FTP Armored Cable

Cat 6A U/FTP Armored Cable combines individually foil-screened twisted pairs with SWA or SWB mechanical protection.

The current ETK Kablo construction uses foamed polyethylene insulation cladded with solid polyethylene. Every twisted pair receives an individual Al/PET foil screen.

A tinned copper earthing wire supports the screened-pair system. The cable then receives a halogen-free inner jacket, the selected SWA or SWB layer and a halogen-free outer jacket.

The pair foils address electromagnetic behavior. The steel layer addresses mechanical exposure.

Cat 6A S/FTP Armored Cable

Cat 6A S/FTP Armored Cable combines individually foil-screened pairs, an overall tinned copper braid and an additional steel mechanical-protection layer.

The current ETK Kablo S/FTP armored construction includes:

• Solid copper conductors
• Foamed PE insulation with solid PE skin
• Al/PET foil around each twisted pair
• Tinned copper earthing wire
• Overall tinned copper braid
• Halogen-free inner jacket
• Steel wire armor or steel wire braid
• Halogen-free outer jacket

The individual foil screens and tinned copper braid provide electromagnetic screening. The separate SWA or SWB layer provides mechanical protection.

U/UTP vs U/FTP vs S/FTP Armored Cat 6A

Architecture	Individual Pair Foils	Overall Copper Braid	Steel Mechanical Protection
U/UTP Armored	No	No	Yes
U/FTP Armored	Yes	No	Yes
S/FTP Armored	Yes	Yes	Yes

The electromagnetic environment should determine the Ethernet-screening architecture. The physical route should determine whether SWA or SWB mechanical protection is appropriate.

500 MHz Cat 6A Armored Ethernet Performance

The current Cat 6A armored product documentation specifies transmission characteristics through 500 MHz.

Relevant parameters include:

• Insertion loss
• Near-end crosstalk (NEXT)
• Power-sum NEXT
• Equal-level far-end crosstalk
• Power-sum equal-level far-end crosstalk
• Return loss
• Characteristic impedance
• Propagation velocity

The steel mechanical layer does not change the underlying Category 6A frequency classification.

Cat 6A Armored Cable for 10 Gigabit Ethernet

Cat 6A armored cable can support 10GBASE-T 10 Gigabit Ethernet when the complete installed structured-cabling channel meets the applicable Category 6A requirements.

Potential applications include:

• Industrial Ethernet
• Factory networks
• Energy and utility infrastructure
• Outdoor technical routes
• IP surveillance networks
• Industrial automation
• Transport infrastructure
• Telecommunications facilities
• Technical buildings
• Mechanically exposed data-network routes

The armor changes the mechanical protection of the cable but does not increase the standardized Ethernet data rate or transmission distance.

10GBASE-T up to 100 Meters

Category 6A is designed to support 10GBASE-T over a full balanced-copper structured-cabling channel when the complete installed system meets the applicable requirements.

A typical channel can extend to 100 meters, normally including up to 90 meters of permanent-link cable together with patch and equipment cords.

SWA or SWB protection does not extend the standardized copper Ethernet channel distance.

Cat 6A Armored Cable for Industrial Ethernet

Industrial environments can expose data cables to physical stresses that are uncommon in standard office structured cabling.

Cat 6A armored cable provides an additional mechanical layer for fixed routes through manufacturing facilities, technical areas, utility infrastructure and industrial pathways.

Electrical screening should be selected separately. U/UTP can suit controlled electromagnetic environments, while U/FTP or S/FTP can provide additional pair-level or overall screening where required.

Cat 6A Armored Cable for Data Centers and Technical Facilities

Some data centers and technical facilities require network cabling outside conventional protected indoor pathways.

Where a Cat 6A route faces increased mechanical exposure, SWA or SWB can provide additional protection while maintaining 500 MHz Category 6A transmission capability.

For conventional rack, raised-floor and tray installations without unusual mechanical exposure, a standard non-armored Cat 6A construction can remain more appropriate.

Armor should therefore follow a genuine mechanical requirement rather than being selected simply because the network carries 10 Gigabit Ethernet.

Cat 6A Armored Cable for Outdoor Networks

The current Cat 6A armored products use UV-resistant halogen-free inner and outer jackets.

This construction can be relevant to demanding fixed routes where environmental and mechanical requirements form part of the project.

However, outdoor suitability should still be evaluated according to the exact installation conditions. The presence of steel armor alone does not automatically confirm every moisture, chemical or buried-installation requirement.

Cat 6A Armored Cable for Cable Trays

Industrial cable trays can contain data, instrumentation, control and power infrastructure within the same facility.

Where an Ethernet route faces increased risk of accidental mechanical damage, an armored Cat 6A construction can provide additional protection.

U/FTP or S/FTP versions can also address electromagnetic requirements where the installation specification calls for screened 10 Gigabit Ethernet cabling.

Applicable separation requirements from power circuits should still be followed.

Cat 6A Armored Cable for Underground Ducts

Armored Cat 6A can be relevant to underground duct routes where additional mechanical protection is required.

However, underground pathways can also introduce moisture, standing water, pulling tension and other environmental conditions.

These requirements should be specified separately. SWA or SWB should not automatically be treated as proof that a cable suits every underground or flooded duct installation.

Can Cat 6A Armored Cable Be Direct Buried?

Direct-burial suitability should be determined from the complete cable construction and the conditions of the installation.

Steel mechanical protection can improve resistance to physical exposure, but direct-burial routes can also require specific moisture, water-blocking, chemical, crush, tensile or environmental characteristics.

For a direct-burial project, buyers should provide the installation conditions during the RFQ so that ETK Kablo can confirm the appropriate cable construction.

Armored Cat 6A vs Standard Cat 6A Cable

Feature	Armored Cat 6A	Standard Cat 6A
Category Frequency	500 MHz	500 MHz
10GBASE-T	Supported within compliant channel	Supported within compliant channel
Steel Mechanical Protection	Yes	No
Electrical Screening	Depends on U/UTP, U/FTP or S/FTP	Depends on selected Cat 6A construction
Main Selection Driver	Mechanical exposure + network requirement	Network and electromagnetic requirements

The steel protection layer is therefore the defining difference. Armor does not create a higher Ethernet category than Cat 6A.

Armored Cat 6A vs Cat 6 Armored Cable

Characteristic	Cat 6 Armored	Cat 6A Armored
Category Frequency	250 MHz	500 MHz
Primary Ethernet Application	Gigabit Ethernet	10GBASE-T
Mechanical Protection	SWA or SWB	SWA or SWB
Main Difference	Cat 6 transmission architecture	Cat 6A transmission architecture

The armor concept can remain similar while the Ethernet core changes substantially in bandwidth and transmission requirements.

Armored Cat 6A vs Shielded Cat 6A

The words armored and shielded describe different functions.

Shielding addresses electromagnetic interference and crosstalk.

Armor addresses mechanical protection.

For example, Cat 6A U/UTP SWA is mechanically armored but has no dedicated foil or copper-braid screen around the Ethernet pairs.

By contrast, standard Cat 6A S/FTP contains extensive electromagnetic screening but does not contain SWA or SWB mechanical armor.

Armored Cat 6A vs Aerial Ethernet Cable

Armored and aerial constructions should not be treated as interchangeable.

Construction	Main Mechanical Function
Armored Cable	Protects the cable against mechanical exposure
Aerial Cable with Messenger	Provides structural support for an overhead span

A route requiring an overhead span should use an aerial design intended for that purpose. A route requiring protection against mechanical damage can require an armored design.

Armored Cat 6A vs Fiber Optic Cable

Armored copper Cat 6A and armored fiber optic cable serve different network requirements.

Cat 6A provides familiar copper Ethernet connectivity and can form part of compatible Power over Ethernet systems.

Fiber optic cable provides electrical isolation, immunity to electromagnetic interference and much longer transmission distances.

For long building-to-building links, industrial infrastructure or electrically complex routes, project engineers should evaluate both architectures before final specification.

LSOH Cat 6A Armored Cable

The six Cat 6A SWA and SWB products use halogen-free inner and outer jackets.

The exact product documentation includes applicable tests for:

• Smoke density
• Single-cable flame retardancy
• Corrosive-gas characteristics
• Halogen content

LSOH or LSZH describes material and reaction-to-fire characteristics. It should not be confused with fire-resistant circuit integrity such as FE180 or PH120.

Cat 6A Armored Cable Electrical Characteristics

Parameter	Published Value
Conductor Resistance at 20°C	Max. 94 Ω/km
Insulation Resistance at 20°C	5000 MΩ/km
Mutual Capacitance	Max. 56 nF/km
Resistance Unbalance	2%
Propagation Velocity	78–80%
Characteristic Impedance	100 Ω ±5%
Operating Voltage	125 V DC
Test Voltage	1200 V DC for 1 minute

Cat 6A Armored Cable Mechanical Characteristics

The current Cat 6A armored product documentation specifies:

• Minimum bending radius: 8xD
• Operating temperature: -20°C to +60°C
• SWA or SWB steel mechanical protection
• UV-resistant halogen-free inner jacket
• UV-resistant halogen-free outer jacket

Exact cable diameter, weight and packing requirements should be confirmed from the selected product documentation during quotation.

Cat 6A Armored Cable Standards

The current ETK Kablo Cat 6A armored product documentation references:

• ANSI/TIA-568-C.2
• IEC 61156-5
• IEC 11801

The product documentation also includes Category 6A electrical-performance data through 500 MHz.

Project specifications can require different editions or additional approvals, so procurement teams should verify the required documentation for the exact supplied product.

Cat 6A Armored Cable and Power over Ethernet

Cat 6A armored cable can form part of compatible Power over Ethernet systems.

The SWA or SWB layer does not determine PoE capability. Remote powering depends primarily on the copper-pair electrical characteristics and the thermal conditions of the installed cable system.

Important factors include:

• Conductor resistance
• Resistance unbalance
• Network distance
• Cable bundle size
• Ambient temperature
• Installation pathway
• Required PoE level

Mechanical armor should therefore be considered separately from the PoE electrical and thermal design.
