Understanding Standards A and B
- Standard A, also known as RJ-45 JACK TIA/EIA 568A STANDARD, is used when connecting different devices such as PC, Switch, or Switch to Router.
T568A consists of: 1. White green 2. Green 3. White orange 4. Blue 5. White blue 6. Orange 7. White brown 8. Brown.
- Standard B, also known as RJ-45 JACK TIA/EIA 568B STANDARD, is used when connecting similar devices like PC to PC, PC to Router, or PC to hub.
T568B includes: 1. White orange 2. Orange 3. White green 4. Blue 5. White blue 6. Green 7. White brown 8. Brown.
In reality, crimping network cables in any order that matches at both ends can establish a connection. However, why bother crimping network cables in standard A or B? Simply because crimping cables according to your preference, in a random manner, may result in interference and, of course, poor network quality.
Moreover, crimping network cables in standard A or B is not difficult and provides us with the best quality. For IT Support, Network, or HelpDesk professionals, it takes no more than 5 minutes to understand and master crimping network cables in standard A or B.
Guide to Crimp Network Cables in A or B Standard
Tools Needed:
- RJ45 standard crimping tool, a popular type with a cost of around 80,000 Vietnamese dong.
- Specialized wire cutting tool, the blade of the crimping tool can be used as a substitute.
- Most common RJ45 network crimping plugs, available at any computer accessory store.
- Naturally, black eight-strand network cable.
- Network cable connection testing tool (may not be necessary).
In this tutorial on crimping network cables in standard A or B, Mytour will guide you through crimping in the T568B standard, the most popular type widely used in modern offices. The T568A type is similar, differing only in the position of the wires.
Step 1: The initial task when crimping A or B standard network cables is to peel off the outer insulation. Mytour suggests cutting approximately 2 - 3 cm if you're not yet proficient.
Step 2: Untwist the 8 strands and arrange their colors according to the T568B standard as you learned earlier.
Step 3: Then gather the strands in the correct color order we discussed earlier. Here, use scissors to cut so that all wire ends are equal.
Step 4: Next, insert the network cable into the RJ45 connector according to the standard we analyzed earlier, then use pliers to crimp and secure it into the cable.
At this point, we have successfully crimped A or B standard network cables. The method described can be applied to any system you are operating.
So now you have the answer to why crimp network cables in A or B standard, as well as the best current crimping practices. Nowadays, devices like Routers and Switches have the ability to detect and provide the best features to reduce interference. Therefore, whether you crimp T568B or T568A is not as crucial as before. However, IT Support professionals or readers researching this field should be aware of these nuances.
In case you only have 4 wires instead of the usual 8, you may wonder how to crimp them. Is there a difference between crimping 4 wires and 8 wires? Learn about the crimping of 4-core standard network cables here and follow the instructions provided in the article.
