Semi-Finished F/FTP CAT6a LAN Cable
1. LANCable Construction (Core Only – No Outer Jacket)
| Component | Description |
|---|---|
| Conductor | Solid bare copper, 23 AWG (0.57 mm nominal), IEC 60228 Class 1 |
| Insulation | HDPE (High-Density Polyethylene), color-coded to TIA/EIA-568-B |
| Twisted Pairs | 4 pairs (8 conductors total), tightly twisted for crosstalk mitigation |
| Pair Shielding | Each pair wrapped in individual aluminum foil (Al/PET) |
| Overall Shielding | Full-size aluminum-polyester foil wrap enclosing all four pairs |
| Drain Wire | Tinned copper wire, in contact with overall foil, for effective grounding |
| Separator | Optional PE cross-web or spline to enhance NEXT/PSNEXT performance |
| Outer Jacket | Not included (core supplied for jacket extrusion) |
2. Electrical & Performance Characteristics
| Parameter | Typical Value (@100 MHz) |
|---|---|
| Impedance | 100 ± 15 ohms |
| Attenuation | ≤ 21.9 dB/100m |
| NEXT | ≥ 65 dB |
| PSNEXT | ≥ 62 dB |
| Return Loss | ≥ 20 dB |
| DC Resistance | ≤ 9.38 ohms/100m |
| Propagation Delay | ≤ 534 ns/100m |
| Delay Skew | ≤ 44 ns/100m |
Meets or exceeds the requirements of TIA-568.2-D and ISO/IEC 11801 Class EA.
3.Key Advantages
Dual shielding (foil on each pair + overall foil) for enhanced EMI/RFI protection
Improved alien crosstalk suppression, especially important for dense installation environments
Ideal core cable for PoE, PoE+, and 10GBASE-T systems
Enables customized jacket materials and CPR classes (B2ca / Cca / Dca) based on downstream production needs
4.Supply Format
| Specification | Description |
|---|---|
| Core OD | Approx. 6.3 – 6.7 mm (without jacket) |
| Standard Length | 1,000m / 2,000m wooden drums |
| Packaging | Wooden reel with PE film wrapping |
| Marking | Bare core – no printing (for OEM branding) |
| Outer Jacket | Not included (PVC/LSZH/PE to be added) |
5.Application Scenarios
Final assembly into CAT6a LAN cables with LSZH, PE, or PVC sheaths
High-performance data cables for enterprise networks, data centers, and EMI-prone environments
Used in custom shielded LAN harnesses, industrial Ethernet, and PoE deployments
Suitable for CPR-certified cable manufacturing when combined with compliant outer jackets
6. Optional Customizations
Drain wire size (e.g., 0.4–0.5 mm² tinned copper)
Foil material type and thickness (standard 0.025–0.05 mm Al/PET)
Conductor coating (bare or tinned copper)
Optimized twist lay lengths for enhanced NEXT/PSANEXT control
X-shaped central separator (for mechanical structure & electrical isolation)
