Semi-Finished S/FTP CAT6 LAN Cable
Individually Screened Pairs Plus Braid for High Interference Sites
Product Overview
What This Product Is
S/FTP CAT6 is the double-shielded core: each pair individually wrapped in aluminium-polyester foil of 25 μm or more, and the whole assembly inside a tinned copper braid at 60 to 80 percent coverage. It outperforms F/UTP and U/FTP where HVAC plant, generators or power runs share the route, and it is the core behind CPR fire-rated LAN cable for data centres and public buildings. Jacketing, printing and classification stay on your side.

Key Benefits
What It Gives Your Production Line
Alien Crosstalk Controlled
Individually screened pairs plus an overall braid protect NEXT and PSNEXT margin even in dense bundles.
Designed for PoE and AV Over IP
Supports 1000BASE-T with PoE and PoE+ under IEEE 802.3af and 802.3at, digital video, VoIP and building automation.
Concentric and Round for Fast Jacketing
Stable roundness and uniform lay lengths reduce jacket bulging and improve extrusion line yield.
Any Outer Sheath Accepted
PVC, LSZH under IEC 60332 and CPR Dca to B2ca, or PE for outdoor and direct-burial finishing.

Problems It Solves
The Reasons Buyers Move To This Product
Electrically Hostile Installations
Generators, drives and HVAC plant break unshielded links. Two shield layers keep the channel inside specification.
Braiding and Taping Together Are Slow
Running foil taping and braiding in one plant is machine-intensive. The finished core removes both steps.
Grounding Must Be Consistent
A tinned copper drain wire of 0.4 to 0.5 mm² is built in, so grounding continuity does not depend on assembly practice.

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
- Braid coverage within the 60 to 80 percent range
- Foil thickness from 25 μm
- Drain wire 0.4 or 0.5 mm²
- Optional PE cross-web spline
- Jacket compound chosen at your finishing stage
Use Guide
Working With It On Your Line
- Terminate the braid to the connector shell and the drain wire to the same ground point to avoid a shield loop.
- Do not exceed the bend radius during jacketing; crushed pair foils show up as NEXT failures.
- Check pair foil overlap on a cut sample from every drum.
- Keep the braid clean and dry at storage so solderability is preserved for assembly work.

FAQ
Semi-Finished S/FTP CAT6 LAN Cable FAQ
How does S/FTP compare with F/UTP and U/FTP?
S/FTP has foil on each pair and a braid over the whole core. It outperforms F/UTP and U/FTP in electrically noisy environments such as areas near HVAC systems, generators or power lines.
What is the minimum order?
Typically 5 to 10 km per specification.
What braid coverage is supplied?
Tinned copper braid at 60 to 80 percent optical coverage.
Which jackets can be applied to this core?
PVC for general use, LSZH for indoor fire-safe zones under IEC 60332 or CPR Dca to B2ca, and PE for outdoor or direct-burial cable.
What drain wire size is used?
Tinned copper at 0.4 to 0.5 mm², which keeps grounding continuity consistent.
