Semi-Finished UTP CAT5e LAN Cable
Unjacketed CAT5e Core for High Volume LAN Cable Production
Product Overview
What This Product Is
The UTP CAT5e core is four HDPE-insulated pairs with controlled lay length and no outer jacket. It is bought by plants that jacket, print and package their own LAN cable, and it supports 100 MHz bandwidth and 1000BASE-T over 100 metres. Core OD runs about 4.6 to 5.2 mm, which is tight enough that a jacketing line can hold wall thickness at speed.

Key Benefits
What It Gives Your Production Line
Priced for Volume Cabling Work
CAT5e remains the cost-effective choice for standard office and residential links, and buying the core keeps the finished cable competitive.
Jacket Type Chosen per Market
PVC for general indoor use, LSZH for fire-rated buildings under IEC 60332 or CPR Dca/Cca, PE for outdoor and direct burial.
Dimensional Control for Fast Extrusion
Tight OD control and stable roundness keep concentricity high when the jacket line runs at speed.
Terminates Cleanly
Standard RJ45 plugs, keystone jacks and punch-down blocks all work with the finished cable.
Application Scenarios
Where It Is Used
- OEM LAN cable manufacturing for commercial and residential cabling
- Custom patch cable production lines
- Multi-core harnesses and communication panels
- Cost-sensitive structured cabling projects
Who It Is For
Who Buys It
- LAN cable plants running jacketing and printing only
- Patch cord assemblers who buy core by the drum
- Brands that need CPR labelling under their own name
Problems It Solves
The Reasons Buyers Move To This Product
Twisting Capacity Limits Output
Pair twisting and cabling is the slow stage in LAN production. Buying the core removes that bottleneck from your plant.
Jacket Rules Differ by Country
One core plus three jacket compounds covers general, fire-rated and outdoor markets without new cable designs.
Print Legend Belongs to the Brand
Cores are supplied unprinted so the legend, batch code and compliance marks are applied by you.

Manufacturing And Quality Control
How It Is Produced And Checked
Conductors are insulated in HDPE and colour-coded, twisted into pairs with lay length controlled pair by pair, then shielded with foil and where specified a braid. Electrical performance is verified against the published limits before the core is reeled. The jacket is not applied.
Conductor And Insulation
Solid bare copper to IEC 60228 Class 1 insulated in colour-coded HDPE.
Lay Length Control
Pair twist pitch controlled per pair, which is what decides NEXT and PSNEXT margin.
Shield Application
Foil coverage and drain wire contact checked where the construction is shielded.
Electrical Testing
NEXT, PSNEXT, return loss, attenuation and delay skew checked against the published limits.
Drum Packing
PE film-wrapped wooden drums, cores left unprinted for your own marking.
Customisation Options
What Can Be Changed
- Bare or tinned copper conductor
- With or without PE cross-filler
- Different insulation thicknesses for tuned OD control
- Low-torque twist pitches per pair
- Compatible with UL, ETL, CPR Dca/Cca, CE or custom compliance as needed
Use Guide
Working With It On Your Line
- Run a pair-map and impedance check on a sample from each drum before jacketing a long order.
- Hold pay-off tension steady — over-tension opens the lay length and degrades NEXT.
- Keep drums dry; HDPE insulation is stable but surface moisture disturbs jacket adhesion.
- Print the compliance legend only after the jacket cools, so the mark does not distort.

FAQ
Semi-Finished UTP CAT5e LAN Cable FAQ
What conductor size is used?
Solid bare copper, 24 AWG with a 0.51 mm nominal diameter, to IEC 60228 Class 1.
Does the core come printed?
No. Cores are supplied unmarked so your own print legend and compliance marking are applied at the jacketing stage.
What is the minimum order quantity?
Typically 3,000 to 5,000 metres per type.
Which jacket materials suit this core?
PVC for general indoor use, LSZH for fire-safe buildings under IEC 60332 or CPR Dca/Cca, and PE for outdoor duct or direct burial.
Can the conductor be tinned?
Yes. Bare or tinned copper is available, along with optional PE cross-filler and adjusted twist pitches.
