| Cat6a | 10 Gigabit Ethernet (10GBase-T) | 100 meters (328 feet) |
| Cat7 | 10 Gigabit Ethernet (10GBase-T) | 100 meters (328 feet) for shielded versions |
Consider the following factors when selecting a cable type:
- Network speed requirements
- Distance between devices
- Budget
- Shielding requirements (for environments with electrical noise)
Stripping the Cable Sheath
Once you have your Ethernet cable and tools, you can begin stripping the cable sheath. This is the outer layer of the cable that protects the inner wires.
Step 1: Measure and mark the cable
Before you start stripping the cable sheath, you need to measure and mark where you want to make the cut. This will help you ensure that you cut the sheath at the correct length.
To measure the cable, use a tape measure or ruler to determine the length of the cable that you need. Then, mark the spot on the cable where you want to make the cut using a pen or marker.
Step 2: Score the cable sheath
Once you have marked the spot where you want to make the cut, you need to score the cable sheath. This will help you to cut the sheath cleanly and easily.
To score the cable sheath, use a utility knife or a cable stripper to make a small cut around the circumference of the cable. Be careful not to cut the inner wires.
Step 3: Strip the cable sheath
Once you have scored the cable sheath, you can strip it off the cable. To do this, simply pull on the sheath until it comes off. You may need to use a pair of pliers to help you pull the sheath off.
Once the sheath is removed, you will be left with the inner wires of the Ethernet cable. These wires are color-coded to help you identify them.
Here is a table summarizing the steps for stripping the cable sheath:
| Step | Description |
|---|---|
| 1 | Measure and mark the cable. |
| 2 | Score the cable sheath. |
| 3 | Strip the cable sheath. |
Preparing the Conductors
Preparing the conductors is a crucial step in Ethernet cable making, as it ensures the proper transmission and reception of data signals. Follow these steps to prepare the conductors:
1. Straighten the Conductors
Uncoil the Ethernet cable and straighten any kinks or bends in the conductors. Straight conductors will facilitate easier handling and ensure a clean crimp connection later.
2. Cut the Conductors
Determine the desired length of the Ethernet cable and cut the conductors to that length using a sharp wire cutter. Ensure that the cuts are clean and perpendicular to the conductor’s axis.
3. Strip the Insulation
Using a wire stripper, carefully remove approximately 1 inch of insulation from the ends of the conductors. Avoid nicking or cutting the conductors during this process.
4. Tin the Conductors (Optional)
Tinning the conductors involves coating the exposed ends with a thin layer of solder. This step is optional but recommended, as it reduces oxidation, improves solderability, and ensures a more secure connection.

Inserting the Conductors into the RJ-45 Connector
1. Strip the Outer Jacket
Carefully strip approximately 1 inch (2.5 cm) of the outer jacket off the end of the cable. Avoid cutting into the inner conductors.
2. Untwist the Pairs
Gently untwist the four twisted pairs of conductors for about 1 inch (2.5 cm). Do not pull too hard, as you may break the wires.
3. Straighten the Conductors
Using your fingers, straighten the individual conductors, ensuring they are neatly aligned and free of kinks.
4. Determine the Wiring Scheme
Select the desired wiring scheme (T568A or T568B) and refer to the following table for the correct conductor order:
| Conductor | T568A | T568B |
|---|---|---|
| Orange-White | Pin 2 | Pin 1 |
| Orange | Pin 1 | Pin 2 |
| Green-White | Pin 3 | Pin 6 |
| Blue | Pin 6 | Pin 5 |
| Blue-White | Pin 5 | Pin 4 |
| Green | Pin 4 | Pin 3 |
| Brown-White | Pin 7 | Pin 8 |
| Brown | Pin 8 | Pin 7 |
5. Insert the Conductors into the RJ-45 Connector
Carefully insert the conductors into the RJ-45 connector, following the correct order for the chosen wiring scheme. Push the conductors all the way until they reach the end of the connector. Ensure that each conductor is fully seated and there are no gaps or loose connections.
