Semi-Finished LAN Cable S/FTP CAT5e
1. Cable Structure
| Component | Description |
|---|---|
| Conductor | Solid bare copper, 24 AWG (0.51 mm nominal), IEC 60228 Class 1 |
| Insulation | High-density polyethylene (HDPE), color-coded to TIA/EIA-568-B |
| Twisted Pairs | 4 pairs (8 wires total), precision lay-length for NEXT control |
| Pair Shielding | Each pair individually wrapped with Aluminum-Polyester Foil (Al/PET) |
| Overall Shielding | Tinned copper braid shield, ≥60–80% optical coverage |
| Drain Wire | Tinned copper wire for effective grounding continuity |
| Separator (Optional) | Central PE cross-web (spline) for additional mechanical/electrical stability |
| Outer Jacket | Not included – core-only cable for downstream processing |
2. Electrical & Performance Characteristics
| Parameter | Typical Value (@100 MHz) |
|---|---|
| Characteristic Impedance | 100 ± 15 ohms |
| NEXT (Near-End Crosstalk) | ≥ 45 dB |
| PSNEXT | ≥ 43 dB |
| Return Loss | ≥ 16 dB |
| Attenuation | ≤ 22.0 dB/100m |
| DC Conductor Resistance | ≤ 9.5 ohms/100m |
| Propagation Delay | ≤ 538 ns/100m |
| Delay Skew | ≤ 45 ns/100m |
Conforms to TIA/EIA-568.2-D, ISO/IEC 11801 Class D, and EN 50173
3. Outstanding Advantages
1. Full Shielded Architecture for EMI Immunity
Foil on each pair ensures strong internal signal separation
Braided shield deflects external interference from motors, fluorescent lights, HVAC, etc.
2. Superior Signal Integrity in Noisy Environments
Maintains excellent NEXT, return loss, and attenuation performance
Reliable for 1000BASE-T, PoE, VoIP, and industrial Ethernet systems
3. High Adaptability for OEM Production
Compatible with all outer jacket materials:
PVC for commercial LAN cables
LSZH for CPR-compliant fire-safe environments (Dca–B2ca)
PE for outdoor or duct applications
Supports custom printing, color-coding, and regional compliance marking
4. Engineered for Manufacturing Efficiency
Smooth OD control and stable concentricity optimize extrusion performance
Tight twist pitch control ensures high-quality electrical matching per batch
VI. Packaging & Supply Format
| Item | Specification |
|---|---|
| Core OD (no jacket) | Approx. 5.4 – 6.2 mm |
| Reel Lengths | 1,000m / 2,000m wooden drums |
| Packaging | PE-wrapped wooden reels or palletized rolls |
| Core Marking | Unprinted core – for post-jacketing marking |
| MOQ | 3,000 – 5,000 meters/order |
