Cat 5e SWB Cable for Mechanically Protected Gigabit Ethernet Networks

Cat 5e SWB Cable combines Category 5e Ethernet transmission with Steel Wire Braid mechanical protection for industrial, infrastructure and physically demanding network routes. ETK Kablo currently manufactures Steel Wire Braided Cat 5e cables in U/UTP, F/UTP, S/UTP and SF/UTP architectures, allowing electromagnetic screening and mechanical protection to be specified separately.

The current ETK Kablo Cat 5e SWB range uses 24 AWG solid copper conductors and provides Category 5e transmission performance through 100 MHz. Each published construction includes a halogen-free inner jacket, galvanized steel wire braiding and a halogen-free outer jacket. Depending on the selected product, the Ethernet core can remain electrically unshielded or include overall foil, copper braid or combined foil-and-braid screening.

Steel Wire Braid performs a mechanical function. It should not be confused with the tinned copper braid used for electromagnetic screening in S/UTP and SF/UTP cables. This distinction is especially important because some Cat 5e SWB constructions contain both a copper braid and a steel braid for completely different engineering purposes.

What Is a Cat 5e SWB Cable?

A Cat 5e SWB cable is a Category 5e balanced copper Ethernet cable with a Steel Wire Braid around the inner-jacketed data-cable core.

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

The underlying data core retains Category 5e performance through 100 MHz. Therefore, the SWB layer changes the mechanical construction without changing the Ethernet category.

What Does SWB Mean?

SWB means Steel Wire Braid.

ETK Kablo places galvanized steel wire braiding outside the halogen-free inner jacket. A UV-resistant halogen-free outer jacket then surrounds the complete construction.

The SWB layer primarily addresses mechanical protection. It does not define whether the Ethernet pairs use electromagnetic screening.

A complete specification should therefore define both:

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

ETK Kablo Cat 5e SWB Cable Range

Current Product	Ethernet Screening	Mechanical Protection
Cat 5e U/UTP LSOH SWB LSOH	No dedicated metallic data screen	Steel Wire Braid
Cat 5e F/UTP LSOH SWB LSOH	Overall Al/PET foil	Steel Wire Braid
Cat 5e S/UTP LSOH SWB LSOH	Overall tinned copper braid	Steel Wire Braid
Cat 5e SF/UTP LSOH SWB LSOH	Overall Al/PET foil + tinned copper braid	Steel Wire Braid

The current Cat 5e SWB family therefore provides four different electromagnetic-screening architectures with the same basic steel-braided mechanical concept.

Cat 5e SWB Cable Construction

The internal construction changes according to the selected Ethernet screening system. However, all four current products share several important design elements:

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

The F/UTP, S/UTP and SF/UTP versions add different electromagnetic-screening components before the inner jacket.

24 AWG Solid Copper Cat 5e SWB Cable

The current ETK Kablo Cat 5e SWB datasheets specify 24 AWG solid copper conductors across all four published constructions.

Solid copper provides predictable conductor resistance and stable electrical characteristics for fixed Ethernet infrastructure.

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

Professional buyers should distinguish solid-copper Ethernet cables from copper-clad alternatives where network performance, Power over Ethernet and project requirements are important.

Steel Wire Braid for Mechanical Protection

Galvanized steel wire braiding surrounds the inner-jacketed Category 5e core.

The braid provides additional mechanical reinforcement for fixed routes where conventional Ethernet cable can face increased physical exposure.

Potential environments include industrial facilities, technical buildings, infrastructure pathways, cable trays and other fixed installations where additional mechanical protection forms part of the project requirement.

However, Steel Wire Braid should not automatically be interpreted as qualification for every buried, flooded, chemically exposed or continuously moving application. Those conditions should be evaluated separately.

SWB Is Not the Same as Ethernet Shielding

Steel Wire Braid and electromagnetic screening solve different engineering problems.

Component	Main Function
Al/PET foil	Electromagnetic screening
Tinned copper braid	Electromagnetic screening
Tinned copper earthing wire	Supports screen continuity and termination
Galvanized Steel Wire Braid	Mechanical protection

A Cat 5e cable can therefore contain Steel Wire Braid while its Ethernet core remains electrically unshielded.

Likewise, a standard screened Cat 5e cable can contain foil or copper braid without containing a steel mechanical braid.

Cat 5e U/UTP SWB Cable

Cat 5e U/UTP SWB Cable combines an electrically unshielded Category 5e core with Steel Wire Braid mechanical protection.

The current ETK Kablo construction includes:

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

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

This construction demonstrates clearly that Steel Wire Braid does not automatically make an Ethernet cable electrically shielded.

Cat 5e F/UTP SWB Cable

Cat 5e F/UTP SWB Cable combines an overall foil-screened Category 5e core with a separate Steel Wire Braid mechanical layer.

The current construction includes:

• 24 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Polyester wrapping
• Tinned copper earthing wire
• Overall Al/PET foil
• Halogen-free inner jacket
• Galvanized steel wire braiding
• Halogen-free outer jacket

The Al/PET foil addresses electromagnetic interference. The galvanized steel braid provides separate mechanical protection.

The individual twisted pairs remain unshielded in an F/UTP construction.

Cat 5e S/UTP SWB Cable

Cat 5e S/UTP SWB Cable contains two different braid systems.

The current construction includes:

• 24 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Polyester wrapping
• Overall tinned copper braid
• Halogen-free inner jacket
• Galvanized steel wire braiding
• Halogen-free outer jacket

The tinned copper braid forms the electromagnetic screen around the Ethernet core.

The galvanized steel wire braid sits outside the inner jacket and provides mechanical protection.

Two Different Braids in Cat 5e S/UTP SWB

Braided Layer	Material	Main Function
S/UTP Screen	Tinned copper	Electromagnetic screening
SWB Layer	Galvanized steel wire	Mechanical protection

The two braid systems should never be treated as interchangeable simply because both use a braided construction.

Cat 5e SF/UTP SWB Cable

Cat 5e SF/UTP SWB Cable combines overall foil and overall copper-braid screening with a separate Steel Wire Braid mechanical layer.

The current construction includes:

• 24 AWG solid copper conductors
• Solid polyethylene insulation
• Four twisted pairs
• Polyester wrapping
• Tinned copper earthing wire
• Overall Al/PET foil
• Overall tinned copper braid
• Halogen-free inner jacket
• Galvanized steel wire braiding
• Halogen-free outer jacket

The foil and tinned copper braid form the electromagnetic-screening system. The galvanized steel wire braid remains a separate mechanical-protection layer.

Three Metallic Functions in Cat 5e SF/UTP SWB

Metallic Component	Material	Main Purpose
Overall Foil	Al/PET	Electromagnetic screening
Overall Screen Braid	Tinned copper	Electromagnetic screening
Mechanical Braid	Galvanized steel wire	Mechanical protection

Precise terminology is therefore essential. The cable contains both electromagnetic shielding and mechanical reinforcement, but those functions come from different metallic elements.

U/UTP vs F/UTP vs S/UTP vs SF/UTP Cat 5e SWB

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

The electromagnetic environment should determine whether the Ethernet core uses U/UTP, F/UTP, S/UTP or SF/UTP. The mechanical conditions of the route should determine the need for Steel Wire Braid.

100 MHz Cat 5e SWB Performance

The current Cat 5e SWB products publish Category 5e transmission characteristics through 100 MHz.

Relevant electrical 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 5e frequency range. It provides mechanical protection around a 100 MHz Ethernet core.

Cat 5e SWB Cable for Gigabit Ethernet

Cat 5e SWB cable can support 1000BASE-T Gigabit Ethernet when the complete installed structured-cabling channel meets the applicable Category 5e requirements.

Potential applications include:

• Industrial Ethernet
• Factory networks
• IP surveillance
• Building automation
• Utility infrastructure
• Technical buildings
• Warehouses and logistics facilities
• Transport infrastructure
• Commercial infrastructure
• Mechanically exposed Gigabit Ethernet routes

The Steel Wire Braid changes the mechanical construction without increasing the standardized network bandwidth or transmission distance.

Cat 5e SWB Cable Length

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 steel braid does not act as a signal amplifier or repeater.

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

Cat 5e SWB Cable for Industrial Ethernet

Industrial facilities can expose data cables to mechanical risks that differ from protected office pathways.

Steel Wire Braided Cat 5e cable can provide additional protection for fixed Ethernet routes through factories, technical areas, warehouses and infrastructure pathways.

Electromagnetic screening should still be selected independently. U/UTP can suit controlled electromagnetic environments, while F/UTP, S/UTP and SF/UTP provide different screen architectures where required.

Cat 5e SWB Cable for Industrial Automation

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

Cat 5e SWB can provide additional mechanical protection where those fixed network routes pass through physically exposed technical environments.

However, Steel Wire Braid should not automatically be interpreted as continuous-flex, drag-chain or robotic-motion qualification. Those applications require separate cable-design evidence.

Cat 5e SWB Cable for IP CCTV

IP surveillance systems can place Ethernet infrastructure in industrial, utility or mechanically exposed routes.

Cat 5e SWB can provide additional physical protection for network connections serving compatible cameras and switches.

F/UTP, S/UTP or SF/UTP versions can add electromagnetic screening where required, while PoE conditions should be evaluated separately from the mechanical braid.

Cat 5e SWB Cable for Building Automation

IP-based building systems can use Ethernet for monitoring, control and communication.

Where network routes pass through technical areas with increased physical exposure, Steel Wire Braided Cat 5e cable can add mechanical reinforcement.

The electromagnetic-screening architecture should still follow the actual project environment rather than being selected solely because the cable includes SWB.

Cat 5e SWB Cable for Cable Trays

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

Where the data route faces greater physical exposure, Steel Wire Braid can provide an additional mechanical layer.

F/UTP, S/UTP or SF/UTP constructions can also add electromagnetic screening where required.

Applicable separation requirements from power circuits should still be followed.

Cat 5e SWB Cable for Infrastructure Routes

The current Cat 5e SWB constructions 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 specification.

However, outdoor, underground and buried routes can introduce moisture, water, chemical and environmental requirements that exist independently from the Steel Wire Braid.

Those conditions should be defined separately during cable selection.

Can Cat 5e SWB Cable Be Installed Underground?

Steel Wire Braided Cat 5e can be relevant to underground ducts and infrastructure routes where additional mechanical protection is required.

Underground pathways can also expose cables to moisture, standing water, pulling loads and other environmental conditions.

The complete route should therefore be evaluated rather than treating Steel Wire Braid alone as confirmation of suitability for every underground installation.

Can Cat 5e SWB Cable Be Direct Buried?

Direct-burial suitability depends on the complete cable construction and the environmental conditions of the route.

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

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

Cat 5e 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	100 MHz	100 MHz
Current Core Options	U/UTP, F/UTP, S/UTP, SF/UTP	U/UTP, F/UTP, S/UTP, SF/UTP

The route conditions should determine whether SWB or SWA is appropriate. Neither construction should automatically be described as universally superior.

Cat 5e SWB vs Standard Cat 5e Cable

Feature	Cat 5e SWB	Standard Cat 5e
Frequency	100 MHz	100 MHz
Gigabit Ethernet	Supported within compliant channel	Supported within compliant channel
Steel Mechanical Protection	Yes	No
Electrical Screening	Depends on U/UTP, F/UTP, S/UTP or SF/UTP	Depends on selected Cat 5e 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 network category above Cat 5e.

Cat 5e SWB vs Cat 6 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 5e SWB vs Cat 6A SWB Cable

Characteristic	Cat 5e SWB	Cat 6A SWB
Category Frequency	100 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 5e solely because both cable families can use Steel Wire Braid.

Cat 5e SWB vs Aerial Ethernet Cable

Steel Wire Braid and an aerial messenger solve different mechanical requirements.

Construction	Main Purpose
Steel Wire Braid	Provides mechanical reinforcement 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 5e SWB Copper vs Armored Fiber Optic Cable

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

Cat 5e copper provides conventional Gigabit-capable 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 links or electrically complex infrastructure routes, project engineers should compare copper and fiber architectures before final specification.

LSOH Inner and Outer Jackets

The four currently published Cat 5e SWB products use halogen-free inner and outer jackets.

The current technical documentation provides smoke-density, flame-propagation, corrosive-gas and halogen-content test information for these 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 5e 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 5e SWB Product Dimensions

Product	Conductor	Approx. Cable Diameter	Published Packing Lengths
U/UTP SWB	24 AWG solid copper	8.8 mm	500 / 1000 m
F/UTP SWB	24 AWG solid copper	9.8 mm	500 / 1000 m
S/UTP SWB	24 AWG solid copper	8.5 mm	500 / 1000 m
SF/UTP SWB	24 AWG solid copper	8.5 mm	500 / 1000 m

The published dimensions vary according to the exact construction. Buyers should confirm the selected product datasheet and dimensional requirements during quotation.

Cat 5e SWB Mechanical Characteristics

The current downloadable Cat 5e SWB datasheets publish an 8xD minimum bending radius for all four constructions.

The public HTML product pages and downloadable PDFs currently show different operating-temperature ranges. The exact approved temperature requirement should therefore be confirmed from the source documentation before project specification.

Cat 5e SWB Cable Standards

The current ETK Kablo Cat 5e SWB product documentation references:

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

The published transmission-performance data extends through 100 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 5e SWB Cable and Power over Ethernet

Cat 5e SWB cable can form part of compatible Power over Ethernet systems.

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

Relevant design factors include:

• 24 AWG 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.
