Semi-Finished U/FTP CAT6a LAN Cable
1. U/FTP CAT6a LAN Cable Structure (Semi-Finished Core)
| Component | Description |
|---|---|
| Conductor | Solid bare copper, 23 AWG (0.57 mm), per IEC 60228 Class 1 standard |
| Insulation | High-density polyethylene (HDPE), color-coded according to TIA/EIA-568-B |
| Twisted Pairs | 4 pairs (8 wires) – tightly twisted to reduce internal crosstalk |
| Pair Shielding | Each pair individually wrapped with Aluminum-Polyester Foil (Al/PET) |
| Separator | Central X-shaped PE cross filler (optional, depending on design) |
| Drain Wire | Tinned copper drain wire runs parallel to shield (optional) |
| Outer Jacket | Not included (This is a bare cable core for jacketed cable manufacturing) |
2. Electrical Performance (Core Compliance with CAT6a)
| Test Parameter | Typical Value @100 MHz |
|---|---|
| Characteristic Impedance | 100 ± 15 ohms |
| NEXT (Near-End Crosstalk) | ≥ 65 dB |
| PSNEXT (Power Sum NEXT) | ≥ 62 dB |
| Return Loss | ≥ 20 dB |
| Attenuation | ≤ 21.9 dB/100m |
| DC Resistance | ≤ 9.38 ohms/100m |
| Propagation Delay | ≤ 534 ns/100m |
| Skew | ≤ 44 ns/100m |
3.Application Scenarios
Used as core material in LAN cable manufacturing lines
Final product integration for PVC, LSZH, or PE jacketed CAT6a cables
Assembly into structured cabling systems, patch cords, or OEM LAN harnesses
Ideal for EMI-sensitive environments and high-speed structured networks
4.Supply Format
| Specification | Details |
|---|---|
| Core OD | ~6.0 – 6.3 mm (without outer jacket) |
| Standard Lengths | 1,000m or 2,000m reels (custom available) |
| Packaging | Wooden drum, shrink-wrapped |
| Print Marking | Usually without (can be added during final jacketing) |
| Jacket | Not included – core only |
5.Optional Customizations
Cross-filler or cross-web design for better crosstalk control
Pre-attached drain wire for grounding continuity
Bare or tinned copper drain wire
Pair twist pitch adjustment for optimized NEXT/PSNEXT
Optional pull rope for jacket extrusion processes
