There are many ways to make a network cable. A brief introduction is to make the most commonly used RJ45 8-pin network cable:
1. Use the stripping function of the network cable pliers to peel off the skin of the network cable.
At this time you will see eight metal wires intertwined with color and white, four color systems of orange, green, blue, and brown. The intertwined ones are white orange, white green, white blue, white brown, and some It is a little orange, and some are only white. If it is a solid color, be careful not to confuse the four whites! We removed their entanglements separately, paying attention to the order of placement: orange, green, blue and brown, white first, and blue and green interchanged. In other words, the final result is: white orange, orange, white green, blue, white blue, green, white brown, brown (suitable for computers and routers, dial-up modems, and switches).
2. After placing the position, set the network cable flat and straight, and cut it straight with a thread cutter. Wire cutters are usually equipped with network cable pliers. Make sure to cut neatly, and then put the crystal head flat and push it forward. When the lines are neatly arranged from the front of the crystal head, use the crystal of the network cable pliers. The head pressing module squeezes it. This completes the production of one end, and the other end is also the same, you must pay attention to the same order as the front end!
The order of making this kind of network cable is the general B-type network cable making method.
If it is a type A network cable, the order of production is orange-green interchange, and it becomes: white-green, green, white-orange, blue, white-blue, orange, white-brown, and brown. The straight connection is that the crystal heads at both ends of the network cable are A or B. If it is a cross line, one end is A and the other is B.
Direct connection (suitable for computers and routers, dial-up modems, switches) Both ends are white orange, orange, white green, blue, white blue, green, white brown, brown
Cross-connect one end 568A and one end 568B (suitable for computers and computers)
Two current network cable standards:
(1) 568A standard: green and white, green, orange and white, blue, blue and white, orange, brown and white, brown
(2) 568B standard: orange white, orange, green white, blue, blue white, green, brown white, brown (usually use this)
We often need to connect directly in the following situations, such as: computer and switch interconnection, switch and router interconnection. If it is a computer and computing interconnection, a crossover cable is required.
Of course, these network cable production methods are not necessarily used by everyone. Because many network designers usually do not strictly abide by this rule, but if they do not follow this rule, the anti-interference performance and anti-attenuation performance of the network cable will be very poor. It is recommended that the designer strictly follow this order to ensure the best operating state of the network. Therefore, if we are going to repair the network, we must take a good look at how the original old crystal head was made. We just do it in the order, because we are only making a crystal head, so we have to "go the same way in the countryside." Otherwise, it must be operated on both ends and made again in accordance with the standards. In addition, the length of the network cable should not be greater than 100 meters, because the longer the model, the greater the attenuation.
Here are some tips for making network cables: because when building a house, one or more of the cables are often pulled off accidentally, so those substandard manufacturing methods can help us. If we find that one or several of the network cables are broken through multiple tests, we can exchange them. For example, if the white orange and orange are broken, we can’t connect, and the others are connected. Replace white-blue, blue, or white-brown and brown. But be careful, it must be the same on both ends, that is, not according to the standard. Usually, as long as 1, 2, 3, and 6 in the sequence are open, the numbers are A, B or the order of the network cables in the replacement rule of the non-standard mode.

How far(long) the transmitter cover?
The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:
I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).
I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).
I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).
Below are the approximate range of different power FM Transmitters. ( The range is diameter )
0.1W ~ 5W FM Transmitter ：100M ~1KM
5W ~15W FM Ttransmitter : 1KM ~ 3KM
15W ~ 80W FM Transmitter : 3KM ~10KM
80W ~500W FM Transmitter : 10KM ~30KM
500W ~1000W FM Transmitter : 30KM ~ 50KM
1KW ~ 2KW FM Transmitter : 50KM ~100KM
2KW ~5KW FM Transmitter : 100KM ~150KM
5KW ~10KW FM Transmitter : 150KM ~200KM
