Cat 6 SWB Cable for Mechanically Protected Gigabit Ethernet Networks

Cat 6 SWB Cable combines Category 6 Ethernet transmission with Steel Wire Braid mechanical protection for industrial, infrastructure and physically demanding network routes. ETK Kablo currently manufactures Steel Wire Braided Cat 6 cables in U/UTP, F/UTP and SF/UTP architectures, allowing electromagnetic screening and mechanical protection to be specified separately.

The current ETK Kablo Cat 6 SWB range uses 23 AWG solid copper conductors and provides Category 6 transmission performance through 250 MHz. Each published product uses a halogen-free inner jacket, galvanized steel wire braiding and a halogen-free outer jacket. Depending on the selected construction, the Ethernet core can remain electrically unshielded or include overall foil and copper-braid screening.

Steel Wire Braid performs a mechanical function. It should not be confused with the tinned copper braid used for electromagnetic screening in SF/UTP cable. This distinction becomes especially important because one Cat 6 SF/UTP SWB cable contains both a copper braid and a steel braid for completely different engineering purposes.

What Is a Cat 6 SWB Cable?

A Cat 6 SWB cable is a Category 6 balanced copper Ethernet cable with a Steel Wire Braid around the inner-jacketed data-cable core.

The steel braid adds mechanical reinforcement for fixed network routes where conventional Ethernet cable can face greater physical exposure.

The Ethernet core retains Category 6 transmission performance through 250 MHz. Therefore, the SWB layer changes the mechanical construction without changing the cable into another Ethernet category.

What Does SWB Mean?

SWB means Steel Wire Braid.

ETK Kablo places the steel braid outside the inner halogen-free jacket and then applies a halogen-free outer jacket.

The SWB layer primarily provides mechanical protection. It does not define whether the Ethernet core uses electromagnetic shielding.

A complete specification should therefore state both:

• The Ethernet architecture: U/UTP, F/UTP or SF/UTP
• The mechanical protection: Steel Wire Braid (SWB)

ETK Kablo Cat 6 SWB Cable Range

Current Product	Ethernet Screening	Mechanical Protection
Cat 6 U/UTP LSOH SWB LSOH	No dedicated metallic data screen	Steel Wire Braid
Cat 6 F/UTP LSOH SWB LSOH	Overall Al/PET foil	Steel Wire Braid
Cat 6 SF/UTP LSOH SWB LSOH	Overall Al/PET foil + tinned copper braid	Steel Wire Braid

The current published range therefore provides three different electromagnetic architectures with the same basic SWB mechanical concept.

Cat 6 SWB Cable Construction

The exact internal construction changes according to the selected screening architecture. However, the current Cat 6 SWB products share the following key design elements:

• 23 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Star-shaped separator
• Halogen-free inner jacket
• Steel wire braiding
• Halogen-free outer jacket

F/UTP and SF/UTP versions add separate electromagnetic-screening components inside the inner jacket.

23 AWG Solid Copper Cat 6 SWB Cable

The current ETK Kablo SWB datasheets identify all three Cat 6 constructions as 23 AWG solid copper.

Solid copper provides predictable conductor resistance and stable transmission characteristics for fixed structured-cabling installations.

The current technical data publishes a maximum conductor resistance of 94 Ω/km at 20°C.

Professional buyers should distinguish solid-copper Cat 6 cable from copper-clad alternatives when network performance, Power over Ethernet and project specifications are important.

Steel Wire Braid for Mechanical Protection

Steel wire braiding surrounds the inner-jacketed Cat 6 cable core.

This braided steel layer can provide additional mechanical reinforcement where the Ethernet route faces increased physical exposure.

Potential routes include industrial facilities, infrastructure pathways, technical buildings, cable trays and other fixed installations where conventional LAN cable may require additional protection.

The exact installation conditions should still determine cable selection. Steel Wire Braid should not automatically be treated as proof of suitability for every buried, wet, chemically exposed or continuously moving application.

SWB Is Not the Same as Ethernet Shielding

Steel Wire Braid describes the mechanical construction outside the inner jacket.

Electromagnetic shielding sits within the Ethernet cable architecture and uses materials such as Al/PET foil or tinned copper braid.

This distinction explains why an SWB cable can still be U/UTP and electrically unshielded.

Cat 6 U/UTP SWB Cable

Cat 6 U/UTP SWB Cable combines an electrically unshielded Category 6 core with Steel Wire Braid mechanical protection.

The current ETK Kablo construction includes:

• 23 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Star-shaped separator
• Halogen-free inner jacket
• Galvanized steel wire braiding
• Halogen-free outer jacket

No dedicated Al/PET foil or tinned copper electromagnetic braid surrounds the data pairs.

This makes U/UTP SWB an important example of a cable that is mechanically protected but electrically unshielded.

Cat 6 F/UTP SWB Cable

Cat 6 F/UTP SWB Cable combines an overall foil-screened Category 6 core with Steel Wire Braid mechanical protection.

The current construction uses:

• 23 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Star-shaped separator
• Polyester wrapping
• Tinned copper earthing wire
• Overall Al/PET foil
• Halogen-free inner jacket
• Steel wire braiding
• Halogen-free outer jacket

The foil addresses electromagnetic interference, while the steel braid provides separate mechanical protection.

Cat 6 SF/UTP SWB Cable

Cat 6 SF/UTP SWB Cable combines overall foil and copper-braid electromagnetic screening with an additional Steel Wire Braid mechanical layer.

The current construction includes:

• 23 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Star-shaped separator
• Tinned copper earthing wire
• Overall Al/PET foil
• Overall tinned copper braid
• Halogen-free inner jacket
• Steel wire braiding
• Halogen-free outer jacket

The foil and tinned copper braid form the electromagnetic-screening architecture. The separate steel wire braid provides mechanical protection.

Two Different Braids in Cat 6 SF/UTP SWB

Cat 6 SF/UTP SWB contains two different braided metallic layers.

Braided Layer	Material	Main Function
SF/UTP Overall Screen	Tinned copper	Electromagnetic screening
SWB Layer	Steel wire	Mechanical protection

The two braids should never be treated as interchangeable.

The tinned copper braid sits within the Ethernet screening system. The steel wire braid sits outside the inner jacket as the mechanical layer.

U/UTP vs F/UTP vs SF/UTP Cat 6 SWB

Architecture	Overall Foil	Overall Copper Braid	Steel Wire Braid
U/UTP SWB	No	No	Yes
F/UTP SWB	Yes	No	Yes
SF/UTP SWB	Yes	Yes	Yes

The electromagnetic environment should determine the U/UTP, F/UTP or SF/UTP architecture. The physical route should determine the need for Steel Wire Braid.

Why Is There No S/UTP SWB Product in the Current Range?

ETK Kablo's standard Cat 6 family includes an S/UTP category, but the currently published Cat 6 SWB category lists only U/UTP, F/UTP and SF/UTP products.

A project requiring an S/UTP core together with Steel Wire Braid should therefore confirm availability with ETK Kablo instead of assuming that it belongs to the standard published range.

250 MHz Cat 6 SWB Performance

The current Cat 6 SWB products publish transmission characteristics through 250 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 Wire Braid does not increase the Category 6 bandwidth. It provides mechanical protection around a 250 MHz Ethernet core.

Cat 6 SWB Cable for Gigabit Ethernet

Cat 6 SWB cable can support 1000BASE-T Gigabit Ethernet when the complete installed structured-cabling channel meets the applicable Category 6 requirements.

Typical applications include:

• Industrial Ethernet
• Factory networks
• Industrial automation
• IP surveillance
• Building automation
• Energy and utility facilities
• Technical buildings
• Warehouses and logistics sites
• Transport infrastructure
• Mechanically exposed Ethernet routes

The steel braid changes the mechanical construction without increasing the standardized network distance or Category 6 frequency.

Cat 6 SWB Cable Length

The Steel Wire Braid does not extend the normal transmission distance of balanced copper Ethernet.

A structured Ethernet channel commonly uses a maximum total length of 100 meters, normally including up to 90 meters of permanent-link cable together with patch and equipment cords.

The SWB layer does not act as a signal amplifier or repeater.

For substantially longer infrastructure routes, fiber optic cable can provide an alternative transmission architecture.

Cat 6 SWB Cable for Industrial Ethernet

Industrial facilities can expose Ethernet cables to mechanical stresses that differ from protected office environments.

Steel Wire Braided Cat 6 cable can add mechanical protection for fixed network routes through factories, technical areas, warehouses and infrastructure pathways.

Electromagnetic screening should still be selected independently. U/UTP can suit controlled electromagnetic conditions, while F/UTP and SF/UTP add overall metallic screens where required.

Cat 6 SWB Cable for Industrial Automation

Industrial automation systems increasingly use Ethernet between controllers, switches, machines and supervisory equipment.

Cat 6 SWB can provide additional mechanical protection where the network route passes through physically demanding fixed installations.

However, Steel Wire Braid should not automatically be interpreted as continuous-flex, drag-chain or robotic-motion qualification. Those capabilities require separate product documentation.

Cat 6 SWB Cable for IP CCTV

IP surveillance systems can place Ethernet cable in industrial and physically exposed routes.

Cat 6 SWB can provide additional mechanical protection for network connections serving cameras, switches and related infrastructure.

The U/UTP, F/UTP or SF/UTP architecture should follow the electromagnetic conditions of the route, while PoE requirements should be evaluated separately.

Cat 6 SWB Cable for Cable Trays

Industrial cable trays can contain Ethernet, control, instrumentation and power infrastructure.

Where the Cat 6 route faces increased physical exposure, Steel Wire Braid can provide an additional mechanical layer.

F/UTP or SF/UTP versions can also add electromagnetic screening where required.

Applicable separation requirements from power circuits should still be followed.

Cat 6 SWB Cable for Outdoor and Infrastructure Routes

The current ETK Kablo Cat 6 SWB products use halogen-free inner jackets and UV-resistant halogen-free outer jackets.

This construction can be relevant to demanding fixed infrastructure routes where mechanical protection forms part of the project requirement.

However, outdoor, underground and buried installations can introduce moisture, water, chemical and environmental requirements beyond the mechanical steel braid itself.

Those conditions should be defined during cable selection.

Can Cat 6 SWB Cable Be Installed Underground?

Steel Wire Braid can provide mechanical reinforcement for underground duct and infrastructure routes where the project requires additional physical protection.

However, underground installations can also expose cables to moisture, standing water, pulling loads and other environmental conditions.

The complete route should therefore be specified rather than assuming that steel braiding alone qualifies the cable for every underground application.

Can Cat 6 SWB Cable Be Direct Buried?

Direct-burial suitability depends on the complete cable construction and the installation environment.

Steel Wire Braid provides mechanical protection, but buried routes can also require specific moisture, water-blocking, chemical, tensile or environmental characteristics.

Projects requiring direct burial should provide the installation conditions during the RFQ so that ETK Kablo can evaluate the appropriate construction.

Cat 6 SWB vs SWA Cable

Feature	SWB	SWA
Full Name	Steel Wire Braid	Steel Wire Armor
Mechanical Construction	Braided steel-wire layer	Steel wire armor layer
Main Function	Mechanical protection	Mechanical protection
Category Frequency	250 MHz	250 MHz
Current Core Options	U/UTP, F/UTP, SF/UTP	U/UTP, F/UTP, SF/UTP

The cable-route requirements should determine whether SWB or SWA is appropriate. Neither construction should automatically be described as universally preferable.

Cat 6 SWB vs Standard Cat 6 Cable

Feature	Cat 6 SWB	Standard Cat 6
Frequency	250 MHz	250 MHz
Gigabit Ethernet	Supported within compliant channel	Supported within compliant channel
Steel Mechanical Protection	Yes	No
Electrical Screening	Depends on U/UTP, F/UTP or SF/UTP	Depends on selected Cat 6 architecture
Main Selection Driver	Mechanical exposure + network requirement	Network and electromagnetic requirements

The Steel Wire Braid is therefore the defining additional feature. It does not create a higher network category than Cat 6.

Cat 6 SWB vs Cat 5e SWB Cable

Characteristic	Cat 5e SWB	Cat 6 SWB
Category Frequency	100 MHz	250 MHz
Primary Ethernet Positioning	Gigabit Ethernet	Higher-performance Gigabit Ethernet
Mechanical Protection	Steel Wire Braid	Steel Wire Braid

The SWB mechanical principle can remain similar while the Ethernet core changes according to the required network category.

Cat 6 SWB vs Cat 6A SWB Cable

Characteristic	Cat 6 SWB	Cat 6A SWB
Category Frequency	250 MHz	500 MHz
Primary Ethernet Positioning	Gigabit Ethernet	10GBASE-T
Mechanical Protection	Steel Wire Braid	Steel Wire Braid

Projects requiring full-distance 10 Gigabit copper infrastructure should evaluate Cat 6A rather than selecting Cat 6 solely because both families can use the same SWB mechanical concept.

Cat 6 SWB vs Aerial Ethernet Cable

SWB and aerial messenger constructions address different mechanical requirements.

Construction	Main Purpose
Steel Wire Braid	Provides mechanical protection around the cable core
Aerial Messenger	Supports an overhead cable span

An SWB cable should not automatically be treated as an aerial cable. Likewise, a messenger-supported Ethernet cable should not automatically be described as armored.

Cat 6 SWB Copper vs Armored Fiber Optic Cable

Mechanically protected copper Ethernet and armored fiber optic cable address different network requirements.

Cat 6 copper can provide conventional Ethernet connectivity and can form part of compatible Power over Ethernet systems.

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

For long building-to-building or industrial infrastructure links, project engineers should compare both technologies before final specification.

LSOH Inner and Outer Jackets

The three current Cat 6 SWB products use halogen-free inner and outer jackets.

The published documentation includes smoke-density, flame-propagation, corrosive-gas and halogen-content tests for the current constructions.

LSOH or LSZH describes material and reaction-to-fire characteristics. It does not establish defined fire-resistant circuit integrity such as FE180 or PH120.

Cat 6 SWB Electrical Characteristics

Parameter	Current Published Family 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	67–69%
Characteristic Impedance	Nominal 100 Ω
Operating Voltage	250 V DC
Test Voltage	1200 V DC for 1 minute

Current Cat 6 SWB Product Dimensions

Product	Conductor	Approx. Cable Diameter	Published Packing Lengths
U/UTP SWB	23 AWG solid copper	10.1 mm	305 / 500 / 1000 m
F/UTP SWB	23 AWG solid copper	10.4 mm	500 / 1000 m
SF/UTP SWB	23 AWG solid copper	10.9 mm	500 / 1000 m

The exact dimensions and packing requirements should be confirmed during quotation because they vary according to the screening architecture.

Cat 6 SWB Cable Standards

The current ETK Kablo Cat 6 SWB product documentation references:

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

The published transmission-performance tables extend through 250 MHz.

Project specifications can require different standard editions, CPR classifications or additional approvals, so procurement teams should verify the requirements for the exact supplied construction.

Cat 6 SWB Cable and Power over Ethernet

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

The steel braid does not determine PoE capability. Remote powering depends primarily on the electrical and thermal characteristics of the copper pairs.

Relevant design factors include:

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

Mechanical protection should therefore be evaluated separately from the PoE electrical and thermal design.
