Semi-Finished S/FTP CAT5e LAN Cable

Double Shielded CAT5e Core for Electrically Noisy Sites

Product Overview

What This Product Is

S/FTP CAT5e is the most heavily shielded CAT5e construction we supply: every pair is wrapped in aluminium-polyester foil and the whole core sits inside a tinned copper braid, with the jacket left for your line. It is specified where motors, fluorescent lighting or HVAC equipment sit close to the cable route, and it is the core behind CPR-compliant shielded patch cable for airports, hospitals and rail projects.

Key Benefits

What It Gives Your Production Line

Two Shield Layers Doing Different Jobs

Foil on each pair separates the pairs internally, while the braid deflects interference arriving from outside.

Performance Held in Noisy Plant

NEXT, return loss and attenuation stay within CAT5e limits near motors, lighting ballasts and HVAC gear.

Braid Coverage Specified by You

60, 70 or 80 percent and above, so shielding cost matches the installation rather than a fixed catalogue figure.

Built for PoE and Industrial Ethernet

Suits 1000BASE-T, PoE, VoIP and industrial Ethernet runs where downtime is expensive.

Application Scenarios

Where It Is Used

  • S/FTP CAT5e patch cable for EMI-sensitive installations
  • Industrial automation and machine Ethernet
  • Medical equipment and broadcast rooms
  • Data rooms and telecom cabinets
  • Structured cabling in airports, hospitals, smart buildings and rail infrastructure
Who It Is For

Who Buys It

  • Manufacturers of CPR-compliant shielded LAN cable
  • OEM patch cord producers serving industrial customers
  • Cable brands supplying infrastructure and transport projects
Problems It Solves

The Reasons Buyers Move To This Product

Interference Only Shows Up On Site

A cable that passes on the bench can fail beside a variable-speed drive. Double shielding removes that risk before it reaches the installer.

Braiding Capacity Is Scarce

Braiding LAN cores is slow and machine-hungry. Buying the braided core keeps your jacketing line the only thing you schedule.

Fire Rules on Public Buildings

LSZH jacketing on this core produces cable classified for enclosed public spaces without redesigning the core.

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.

  1. Conductor And Insulation

    Solid bare copper to IEC 60228 Class 1 insulated in colour-coded HDPE.

  2. Lay Length Control

    Pair twist pitch controlled per pair, which is what decides NEXT and PSNEXT margin.

  3. Shield Application

    Foil coverage and drain wire contact checked where the construction is shielded.

  4. Electrical Testing

    NEXT, PSNEXT, return loss, attenuation and delay skew checked against the published limits.

  5. Drum Packing

    PE film-wrapped wooden drums, cores left unprinted for your own marking.

Customisation Options

What Can Be Changed

  • Braid coverage 60, 70 or 80 percent and above
  • Single or double-sided Al/PET foil, ≥ 25 μm
  • Drain wire gauge 0.4 mm² or customised
  • Bare or tinned copper conductor
Use Guide

Working With It On Your Line

  • Cut braid ends square and fold back over the jacket during termination so the shield contacts the connector body.
  • Do not crush the core in the haul-off; a flattened braid raises attenuation.
  • Verify braid coverage on a sample rather than trusting appearance — coverage differences are hard to see.
  • Keep the drain wire accessible when you set the jacket stripping length in your finishing instructions.

FAQ

Semi-Finished S/FTP CAT5e LAN Cable FAQ

What does S/FTP mean on this core?

S is the overall tinned copper braid screen and FTP is the foil around each individual twisted pair. Both are present.

What braid coverage is standard?

60 to 80 percent optical coverage, and the exact figure can be specified at 60, 70 or 80 percent and above.

Which directives does the core suit?

It is compatible with RoHS, REACH, UL, CPR and CE requirements; the finished classification depends on the jacket you apply.

How large is the core before jacketing?

Approximately 5.4 to 6.2 mm outer diameter.

Is it suitable for PoE?

Yes. The construction is used for 1000BASE-T, PoE, VoIP and industrial Ethernet applications.
