Semi-Finished S/FTP CAT6 Lan Cable
1. LAN Cable Structure
| Component | Specification |
|---|---|
| Conductor | Solid bare copper, 23 AWG (0.57 mm nominal), Class 1 as per IEC 60228 |
| Insulation | High-density polyethylene (HDPE), precision-extruded, color-coded |
| Twisted Pairs | 4 balanced pairs (8 conductors) with optimized lay-length for NEXT control |
| Pair Shielding | Individually wrapped with Al/PET foil, ≥25μm, 100% coverage |
| Overall Shielding | Tinned copper braid (≥60–80% optical coverage), anti-static and EMI-resistant |
| Drain Wire | Tinned copper, 0.4–0.5 mm², ensures consistent grounding continuity |
| Filler (Optional) | PE cross-web spline or central separator (for enhanced crosstalk performance) |
| Jacket | Not included – intended for later extrusion (PVC, LSZH, PE) |
2. Electrical Performance – Category 6 / Class E
| Parameter | Typical Value @100 MHz |
|---|---|
| Characteristic Impedance | 100 ± 15 ohms |
| NEXT (Near-End Crosstalk) | ≥ 55 dB |
| PSNEXT | ≥ 52 dB |
| Return Loss | ≥ 20 dB |
| Attenuation | ≤ 20.9 dB/100m |
| DC Conductor Resistance | ≤ 9.38 ohms/100m |
| Resistance Unbalance | ≤ 5% |
| Propagation Delay | ≤ 535 ns/100m |
| Delay Skew | ≤ 45 ns/100m |
3. Outstanding Advantages
1. Dual-Layer Shielding
Foil on each pair + braided shield offers exceptional protection against EMI/RFI and alien crosstalk
Outperforms F/UTP and U/FTP in electrically noisy environments, such as near HVAC systems, generators, or power lines
2. Precision Crosstalk Suppression
Individually shielded pairs eliminate internal interference
Delivers consistent NEXT/PSNEXT margin even in high-bundle installations
3. Future-Proof Design for Advanced Networks
1000BASE-T and Gigabit applications with full support for PoE/PoE+ (IEEE 802.3af/at)
Compatible with digital video, VoIP, building automation, and AV over IP
4. OEM-Ready Flexibility
Accepts a wide range of outer sheaths:
PVC for general use
LSZH for indoor fire-safe zones (IEC 60332 / CPR Dca–B2ca)
PE for outdoor/underground direct burial
5. High Manufacturing Efficiency
Stable roundness and concentricity for high-speed jacketing
Uniform lay-lengths minimize jacket bulging and improve extrusion line yield
4. Packaging & Supply Format
| Item | Specification |
|---|---|
| Outer Diameter | ~6.3 – 6.7 mm (without jacket) |
| Standard Reel Lengths | 1000 m / 2000 m |
| Packaging | Wooden drums, PE film-wrapped |
| Core Marking | None – designed for post-extrusion branding |
| MOQ | Typically 5–10 km per specification |
5. Applications
OEM cable manufacturing (CAT6 S/FTP with custom branding)
Data center and telecom environments with strict EMI control
Industrial automation, machine-to-machine Ethernet, medical systems
Public buildings requiring CPR-compliant fire-rated LAN cables
