Product Overview

What This Product Is

The UTP CAT6 core carries four 23 AWG pairs in HDPE insulation, with an optional PE cross-web spline and no outer jacket. It is specified to 250 MHz under TIA/EIA-568.2-D and ISO/IEC 11801 Class E, and conductor diameter tolerance is held to within 0.01 mm so the geometry stays stable through jacketing. Buyers are LAN cable plants that finish, print and box the cable themselves.

Key Benefits

What It Gives Your Production Line

250 MHz Headroom Over CAT5e

NEXT of 55 dB or better and attenuation of 20.9 dB/100m give margin that survives bundled installations.

Spline Option for Crosstalk Control

An optional PE cross-web separates the pairs where NEXT margin has to be maximised.

Tight Conductor Tolerance

Conductor diameter tolerance within 0.01 mm keeps electrical matching consistent from drum to drum.

Every Jacket Type Supported

PVC, LSZH or PE, with colour, striping, printing and branding applied during jacketing.

Application Scenarios

Where It Is Used

OEM manufacture of UTP CAT6 LAN cable
Structured cabling for homes, offices, campuses, retail and hospitality
1G Ethernet, VoIP and IPTV networks
Smart lighting and building data transmission

Who It Is For

Who Buys It

LAN cable manufacturers with jacketing capacity only
Brands selling CAT6 under their own label
Assembly shops producing patch cords and keystone-terminated leads

Problems It Solves

The Reasons Buyers Move To This Product

Twisting Quality Decides CAT6 Pass Rates

Lay length and tension control are where CAT6 cores fail. The core is produced with lay length managed pair by pair.

Bundled Runs Lose Margin

Crosstalk rises when cables are bundled tightly. Optional spline construction protects NEXT and PSNEXT margin.

Compliance Marking Differs by Country

Unprinted cores let one purchase serve several regional labelling requirements.

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
Conductor diameter tolerance ≤ ± 0.01 mm
Specific lay lengths per pair to tune NEXT and PSNEXT
Adapted to your extrusion line compatibility

Use Guide

Working With It On Your Line

Feed the spline straight into the jacket head; a twisted spline pushes the core out of round.
Test NEXT and return loss on a jacketed sample, not on the bare core, because the jacket shifts impedance slightly.
Keep drum-to-drum changeovers marked in your production log so field test failures can be traced.
Store reels flat-wound and upright to protect the pair geometry.
