Semi-Finished UTP CAT5e LAN Cable
1. LAN Cable Structure
| Component | Description |
|---|---|
| Conductor | Solid bare copper, 24 AWG (0.51 mm nominal), IEC 60228 Class 1 |
| Insulation | HDPE (High-Density Polyethylene), precision color-coded per TIA/EIA-568-B |
| Twisted Pairs | 4 pairs (8 conductors), with tightly controlled lay lengths |
| Shielding | None – UTP (Unshielded Twisted Pair) |
| Separator | Optional PE cross-web (filler) for mechanical integrity |
| Jacket | Not included – ready for downstream jacketing (PVC, LSZH, PE) |
2. Electrical & Transmission Performance
| 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 Resistance | ≤ 9.5 ohms/100m |
| Delay Skew | ≤ 45 ns/100m |
| Propagation Delay | ≤ 538 ns/100m |
Standards:
TIA/EIA-568.2-D | ISO/IEC 11801 Class D | EN 50173 | RoHS / REACH Compliant
3.Outstanding Advantages
1. Proven Performance, Competitive Cost
Fully supports 100BASE-T and 1000BASE-T applications
Lower cost alternative to CAT6 while still meeting most modern performance needs
2. Manufacturing Flexibility
Compatible with all jacket types for different installations:
PVC for standard indoor use
LSZH for fire-rated environments (CPR Dca/Cca)
PE for outdoor/direct burial applications
3. High Production Efficiency
Tight dimensional control ensures smooth extrusion, stable roundness, and high cable concentricity
Designed for use on high-speed jacket extrusion lines
4. Easy Termination
Suitable for standard RJ45 connectors, keystone jacks, and punch-down blocks
Reliable electrical performance in home networks, SOHO, CCTV, and basic automation systems
4. Supply Format & Packaging
| Specification | Description |
|---|---|
| Outer Diameter (core) | Approx. 4.6 – 5.2 mm (without jacket) |
| Reel Lengths | 1,000m or 2,000m wooden drums |
| Packaging | Wooden reel, PE film-wrapped |
| Marking | None – ready for OEM jacket printing |
| MOQ | 3,000 – 5,000 meters per type |
