Semi-Finished S/FTP CAT7 LAN Cable
1. Network cable structure
| Component | Specification |
|---|---|
| Conductor | Solid bare copper, 23 AWG (0.57 mm), Class 1 (IEC 60228) |
| Insulation | Foamed polyethylene (FPE) or solid HDPE, color-coded |
| Twisted Pairs | 4 pairs (8 conductors), optimized lay-length for low crosstalk |
| Pair Shielding | Each pair wrapped in Aluminum-Polyester Foil (Al/PET) |
| Overall Shielding | Tinned copper braid, ≥ 70% optical coverage |
| Drain Wire | Tinned copper wire for electrical continuity (optional per jacket design) |
| Separator | Optional PE central filler or non-woven wrapping |
| Outer Jacket | Not included – for OEM-controlled extrusion process |
2. Electrical & Transmission Performance
| Parameter | Typical Value (@600 MHz) |
|---|---|
| Characteristic Impedance | 100 ± 10 ohms |
| NEXT (Near-End Crosstalk) | ≥ 60 dB |
| PSNEXT | ≥ 57 dB |
| Return Loss | ≥ 20 dB |
| Attenuation | ≤ 44 dB/100m |
| DC Resistance | ≤ 9.5 ohms/100m |
| Delay Skew | ≤ 40 ns/100m |
| Propagation Delay | ≤ 530 ns/100m |
Conforms to:
ISO/IEC 11801 Class F
EN 50173-1
TIA-607-C (optional for grounding design)
RoHS, REACH, and CPR-compliant (when jacketed accordingly)
3.Outstanding Advantages
1. Full Shielding for Maximum Noise Immunity
Each pair is individually shielded to eliminate internal pair-to-pair crosstalk
Overall braid shield resists external EMI, making it ideal for data centers, broadcast, and industrial control environments
2. Future-Ready Bandwidth & Speed
Supports 10GBASE-T Ethernet up to 100 meters
Delivers high integrity for data, video, and power (PoE++) simultaneously across demanding backbone or trunking systems
3. OEM Customization Flexibility
Compatible with outer jackets for indoor (PVC/LSZH) or outdoor (PE) environments
Ideal for manufacturing B2ca or Cca CPR-rated cables for the European market
Can be customized with specific twist ratios, drain wires, or enhanced flame-retardant fillers
4. Robust Mechanical Integrity
Thick core structure ensures crush resistance, durability, and stable geometry for high-speed extrusion
Suitable for patch cable production, structured cabling links, or pre-terminated trunk systems
4. Supply Format
| Item | Specification |
|---|---|
| Core Outer Diameter | Approx. 7.5 – 8.0 mm (without jacket) |
| Standard Lengths | 1,000m / 2,000m per wooden reel |
| Packaging | PE-wrapped wooden drums or palletized |
| Print Marking | None – intended for post-extrusion labeling |
| MOQ | 3,000 – 5,000 meters per type |
