## What is Copper Network Cabling?
4
5
Copper cabling is the **traditional medium for Ethernet networks**, using electrical signals to transmit data. It is widely used due to its **affordability, ease of installation**, and suitability for **short- to medium-distance connections**. Common types include **twisted pair cables** such as Cat5e, Cat6, Cat6a, Cat7 and Cat8.

## Why Use Copper Cables?
10
11
### **Cost-Effective and Readily Available**
12
- Lower material and installation costs compared to fibre.
13
- Easier to terminate and test with standard tools.
14
15
### **Power over Ethernet (PoE) Capable**
16
- Copper cables can deliver **both data and power** (up to 90W with PoE++).
17
- Ideal for powering **IP cameras, VoIP phones, and wireless access points**.
18
19
### **Flexible Installation**
20
- Can be installed and maintained by general IT staff.
21
- Works well in both horizontal and vertical cabling runs within 100 meters.

30
| **Distance** | Up to 100m | 500m to 40km+ |
31
| **PoE Support** | Yes | No |
32
| **EMI Resistance** | Moderate (STP) to low (UTP) | Immune |
33
| **Installation** | Easy | Requires skilled installer |
34
| **Durability** | Physically robust | Fragile to bend/tension |
35
| **Cost** | Lower | Higher |
36
| **Bandwidth** | Lower | Extremely high |
37
| **Security** | Easier to tap | Harder to tap |

## Types of Copper Ethernet Cables
42
43
| Cable Type | Max Speed | Max Distance | Shielding | Common Use |
44
|------------|-----------|--------------|-----------|-------------|
45
| Cat5e | 1 Gbps | 100m | UTP/STP | Home & small business |
46
| Cat6 | 10 Gbps (up to 55m) | 100m | UTP/STP | General business use |
47
| Cat6a | 10 Gbps | 100m | Shielded (STP) | Enterprise networks |
48
| Cat7 | 10 Gbps | 100m | Fully shielded | High-interference areas |
49
| Cat8 | 25–40 Gbps | 30m | Fully shielded | Data centres |
50
51
- **UTP (Unshielded Twisted Pair):** Cost-effective, flexible, best for clean environments.
52
- **STP/FTP (Shielded/Foiled Twisted Pair):** Mitigates **EMI**, used in industrial or high-noise environments.

## UK Standards for Copper Cabling
75
76
### **Structured Cabling Standards**
77
- **BS EN 50173-1** → Covers both copper and fibre structured cabling.
78
- **ISO/IEC 11801** → International structured cabling specification.
79
- **BS EN 50310** → Grounding and bonding of ICT cabling.
80
- **BS 6701:2016+A1:2017** → Cabling practices including PoE considerations.
81
82
### **Fire Safety Requirements**
83
- **Low Smoke Zero Halogen (LSZH)** jackets are mandatory for indoor installations.
84
- Cables must comply with the **Construction Products Regulation (CPR)** for fire classification.

## Best Practices for Copper Cable Installation
89
90
### **1. Follow Cable Category Limits**
91
- Do not exceed the specified **maximum run lengths** (typically 90m + 10m patching).
92
- Use the **appropriate category** for the required bandwidth.
93
94
### **2. Proper Cable Management**
95
- Avoid tight bends, kinks, or crushing.
96
- Use **trays, conduits, and velcro ties** to manage cables cleanly.
97
98
### **3. Avoid Electromagnetic Interference (EMI)**
99
- Keep away from electrical sources like lighting circuits and motors.
100
- Use **STP or foil-shielded cables** in high-interference areas.
101
102
### **4. Label and Document**
103
- Label all endpoints and patch panels for quick identification.
104
- Maintain diagrams and spreadsheets for cable routes and IDs.
105
106
### **5. Test and Certify**
107
- Use a cable tester to check for **continuity, wire map, and length**.
108
- Certify using **Fluke or equivalent tools** for compliance with category standards.
