Cat 5e U/UTP Cable for Gigabit Ethernet Networks

Cat 5e U/UTP Cable provides cost-effective unshielded copper connectivity for Gigabit Ethernet, structured cabling, IP surveillance, VoIP, Wi-Fi access points and general LAN infrastructure. ETK Kablo manufactures Cat 5e U/UTP cables with solid copper conductors and PVC, LSOH or PE outer jackets for different indoor and outdoor-oriented network requirements.

The current ETK Kablo Cat 5e U/UTP range uses four unshielded twisted pairs with 0.51 mm solid copper conductors and solid polyethylene insulation. The cables provide Category 5e transmission performance through 100 MHz and can support 1000BASE-T Gigabit Ethernet when the complete installed structured-cabling channel meets the applicable requirements.

U/UTP contains no overall metallic screen and no individual pair screens. Instead, the balanced twisted-pair geometry controls crosstalk and electromagnetic interaction. This makes Cat 5e U/UTP a practical choice for networks where the electromagnetic environment does not require additional foil or braid screening.

What Is Cat 5e U/UTP Cable?

Cat 5e U/UTP is a four-pair balanced copper Ethernet cable with no metallic screen around the complete cable and no screens around the individual twisted pairs.

The designation means:

• U – no overall metallic screen
• UTP – unshielded twisted pairs

Buyers frequently use the simpler term UTP Cat 5e. U/UTP is the more precise structured-cabling notation because it identifies both the overall cable screen and the screening status of the individual pairs.

ETK Kablo Cat 5e U/UTP Cable Range

Product	Outer Jacket	Main Selection Direction
Cat 5e U/UTP PVC	PVC	General structured cabling where PVC materials are permitted
Cat 5e U/UTP LSOH	Halogen-free / low-smoke material	Projects requiring defined smoke and halogen characteristics
Cat 5e U/UTP PE	Polyethylene	Outdoor-oriented Ethernet routes

All three products share the same basic unshielded Category 5e electrical architecture. The outer-jacket material changes according to the intended installation environment.

Cat 5e U/UTP Cable Construction

Component	Current ETK Kablo Construction
Conductor	Electrolytic solid copper
Conductor Diameter	0.51 mm
Approximate AWG Equivalent	Approximately 24 AWG
Insulation	Solid polyethylene
Pair Construction	Four twisted pairs
Overall Metallic Screen	None
Individual Pair Screens	None

0.51 mm Solid Copper Cat 5e Cable

The current ETK Kablo Cat 5e U/UTP products use 0.51 mm solid copper conductors, which correspond closely to the commonly specified 24 AWG conductor size.

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

The current products publish a maximum conductor resistance of 94 Ω/km at 20°C.

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

Why Cat 5e Uses Twisted Pairs

Cat 5e transmits Ethernet signals over balanced pairs of copper conductors.

Each pair uses a controlled twist geometry that helps reduce electromagnetic coupling and crosstalk without requiring metallic screening.

The four pairs then form the complete Ethernet cable core.

This balanced architecture allows U/UTP cable to provide reliable transmission in offices, commercial buildings, residential networks and other environments where electromagnetic noise remains controlled.

Cat 5e U/UTP Has No Metallic Shield

U/UTP should not be described as shielded Ethernet cable.

The current ETK Kablo construction contains:

• Solid copper conductors
• Solid PE insulation
• Four twisted pairs
• Outer jacket

It does not contain an overall Al/PET foil, copper braid or individual pair screens.

Where a project requires additional electromagnetic protection, ETK Kablo offers F/UTP, S/UTP and SF/UTP alternatives within the Cat 5e family.

100 MHz Cat 5e U/UTP Performance

ETK Kablo publishes transmission characteristics for the current Cat 5e U/UTP products 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 current products publish a characteristic impedance of 100 Ω ±5% over the Category 5e frequency range.

Cat 5e U/UTP for Gigabit Ethernet

Cat 5e U/UTP can support 1000BASE-T Gigabit Ethernet when the complete installed channel meets the applicable structured-cabling requirements.

Typical applications include:

• Office LAN networks
• Commercial structured cabling
• Small and medium-sized business networks
• IP surveillance systems
• VoIP and IP telephony
• Wi-Fi access points
• Building automation networks
• General Ethernet infrastructure

The installed channel includes cable, connectors, patch panels, patch cords and field terminations. Each element contributes to the final network performance.

1000BASE-T Uses All Four Twisted Pairs

Gigabit Ethernet over Cat 5e uses all four twisted pairs in the Ethernet channel.

This makes consistent pair geometry, termination quality and conductor performance important throughout the installation.

A cable that meets Category 5e transmission requirements can provide Gigabit Ethernet connectivity without requiring the 250 MHz bandwidth associated with Cat 6.

Cat 5e Cable Length

Balanced copper Ethernet installations commonly use a maximum structured-cabling channel length of 100 meters.

A typical channel includes up to 90 meters of permanent-link cable together with patch cords and equipment cords.

The complete installation should follow the applicable structured-cabling standard rather than extending the cable solely because electrical continuity remains present.

Longer routes can require intermediate active network equipment or fiber optic cabling.

Cat 5e U/UTP vs F/UTP

Feature	Cat 5e U/UTP	Cat 5e F/UTP
Overall Metallic Screen	None	Overall foil
Individual Pair Screens	None	None
Category Frequency	100 MHz	100 MHz
Main Screening Principle	Balanced twisted pairs	Balanced pairs + overall foil
Screen Termination	No metallic screen to terminate	Requires appropriate screened installation

U/UTP provides a simple unshielded architecture for controlled electromagnetic environments. F/UTP adds an overall foil where the project requires additional protection against external electromagnetic interference.

Cat 5e U/UTP vs S/UTP

Cat 5e S/UTP uses an overall metallic braid around four individually unshielded twisted pairs.

U/UTP contains no metallic screen.

The correct construction depends on the electromagnetic conditions and project specification rather than the assumption that screened cable is required for every network.

Cat 5e U/UTP vs SF/UTP

Cat 5e SF/UTP combines an overall foil with an overall braid around four individually unshielded twisted pairs.

This creates a more extensive screen architecture than U/UTP.

However, U/UTP can remain appropriate for offices, commercial networks and other routes where electromagnetic conditions allow an unshielded channel.

Cat 5e U/UTP vs Cat 6 U/UTP

Characteristic	Cat 5e U/UTP	Cat 6 U/UTP
Category Frequency	100 MHz	250 MHz
Primary Ethernet Positioning	Gigabit Ethernet	Professional Gigabit Ethernet
Current ETK Conductor Diameter	0.51 mm	0.57 mm
Current ETK Separator	No star separator listed	Star-shaped separator
Metallic Screening	None	None

Both categories can support Gigabit Ethernet. Cat 6 provides higher standardized bandwidth and tighter transmission-performance requirements, while Cat 5e remains a practical option for networks that primarily require 1 Gigabit connectivity.

Cat 5e U/UTP vs Cat 6A U/UTP

Characteristic	Cat 5e U/UTP	Cat 6A U/UTP
Frequency	100 MHz	500 MHz
Primary Ethernet Positioning	1 Gigabit Ethernet	10GBASE-T
Metallic Screening	None	None
Typical Selection Driver	Cost-effective Gigabit connectivity	Higher-bandwidth 10 Gigabit infrastructure

Both products use an unshielded architecture, but Cat 6A targets substantially higher frequency and network-performance requirements.

Cat 5e U/UTP PVC Cable

Cat 5e U/UTP PVC Cable combines unshielded Category 5e transmission with a UV-resistant PVC outer jacket.

The current ETK Kablo PVC product uses 0.51 mm solid copper conductors, solid polyethylene insulation and four twisted pairs.

The published approximate cable diameter is 5.4 mm.

Current packing lengths are 100 m, 500 m and 1000 m.

PVC provides a conventional material option for fixed structured-cabling projects where PVC materials meet the project requirements.

Cat 5e U/UTP LSOH Cable

Cat 5e U/UTP LSOH Cable uses the same 100 MHz unshielded Ethernet architecture with a UV-resistant halogen-free outer jacket.

The current product uses 0.51 mm solid copper conductors and publishes an approximate cable diameter of 5.4 mm.

The current technical documentation publishes applicable testing for:

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

LSOH or LSZH describes cable-material behavior during combustion. It should not be interpreted as fire-resistant circuit integrity.

Cat 5e U/UTP PE Outdoor Cable

Cat 5e U/UTP PE Cable combines unshielded Category 5e performance with a UV-resistant polyethylene outer jacket.

The current ETK Kablo product uses 0.51 mm solid copper conductors and publishes an approximate overall diameter of 5.5 mm.

Potential applications include:

• Outdoor LAN extensions
• Building-to-building network routes
• Outdoor IP surveillance
• External Wi-Fi access points
• Campus Ethernet networks
• External automation infrastructure

The PE jacket provides an outdoor-oriented material system. It should not automatically be interpreted as steel armor, water blocking or universal direct-burial qualification.

PVC vs LSOH vs PE Cat 5e U/UTP

Jacket	Main Selection Consideration
PVC	General fixed installations where PVC is permitted
LSOH / LSZH	Projects requiring defined smoke and halogen-related material characteristics
PE	Outdoor-oriented routes requiring polyethylene jacket characteristics

The outer-jacket material changes environmental and reaction-to-fire characteristics but does not change the underlying 100 MHz Cat 5e U/UTP electrical architecture.

Cat 5e U/UTP for Office Networks

Cat 5e U/UTP remains a practical architecture for office networks that require reliable Gigabit Ethernet without additional metallic screening.

Potential connections include:

• Desktop computers
• Network printers
• IP telephones
• Access switches
• Wireless access points
• Building-management devices

Where the network environment has controlled electromagnetic conditions and does not require higher Category 6 or Cat 6A bandwidth, Cat 5e can provide an efficient structured-cabling solution.

Cat 5e U/UTP for IP CCTV

IP camera systems frequently use Ethernet for both network communication and remote powering.

Cat 5e U/UTP can support Gigabit-capable surveillance infrastructure and can serve many camera connections where 100 MHz Category 5e performance meets the project requirement.

PVC or LSOH products can serve applicable indoor routes, while PE provides an outdoor-oriented jacket option.

The exact network architecture should consider camera bandwidth, switch capacity, route length and Power over Ethernet requirements.

Cat 5e U/UTP for VoIP

Voice over IP systems transport voice traffic over standard Ethernet infrastructure.

Cat 5e U/UTP can connect compatible IP phones, switches and other voice-network equipment in structured-cabling systems.

Its 100 MHz Category 5e performance provides more than the bandwidth required by individual voice endpoints while also supporting normal LAN traffic.

Cat 5e U/UTP for Wi-Fi Access Points

Wireless access points require a wired Ethernet backhaul connection to the network.

Cat 5e U/UTP can support Gigabit connectivity for compatible access points where the required wired data rate does not exceed the network design.

Projects deploying higher-speed multi-gigabit wireless infrastructure should also evaluate Cat 6 or Cat 6A according to the access-point and switch requirements.

Cat 5e U/UTP for Building Automation

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

Cat 5e U/UTP can provide a cost-effective copper platform for compatible building-management, access-control and automation devices in controlled electromagnetic environments.

Where the route operates in a more electrically demanding industrial environment, a screened Cat 5e construction or a higher-category cable may deserve consideration.

Cat 5e U/UTP and Power over Ethernet

Cat 5e U/UTP can form part of compatible Power over Ethernet systems.

PoE can power devices such as:

• IP cameras
• VoIP telephones
• Wi-Fi access points
• Access-control devices
• Compatible building-network equipment

PoE performance depends on conductor resistance, route length, cable bundle size, ambient temperature and the required power level.

The use of solid copper conductors provides a useful basis for fixed PoE structured cabling, but the complete installation should still follow the applicable PoE design requirements.

Cat 5e U/UTP Electrical Characteristics

Parameter	Current 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	67–69%

Current product documentation publishes:

• Minimum bending radius: 8xD
• Operating temperature: -20°C to +60°C
• Packing lengths: 100 m, 500 m and 1000 m

The exact packing requirement should be confirmed during quotation.

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

The product data publishes transmission performance through 100 MHz.

Project specifications can require a different edition or additional documentation, so procurement teams should verify the requirements for the exact supplied construction.

Flame, Smoke and Halogen Requirements

Fire-related material characteristics vary according to the selected jacket.

The current PVC product publishes single-cable flame-retardancy testing according to IEC 60332-1-2 and equivalent referenced methods.

The current LSOH product additionally publishes smoke-density, corrosive-gas and halogen-related testing.

These tests describe reaction-to-fire and material characteristics. They should not be confused with fire-resistant circuit integrity.
