Some people may scoff at it, saying that the information superhighway not only refers to an optical transmission network distributed throughout the country, but also includes countless functional networks, business networks, and enterprise networks, and it is also necessary to realize that network users can transmit information to each other at any time and anywhere in the form of sound, data, images or videos.

This is true, but the problem is that Huaxia does not have a strong demand for this now. Even in 2020, the United States, which has the most advanced information, will not be able to transfer information to each other at any time and anywhere. There are also many remote places where they don't even have a cell phone signal. How can this day and age demand such fast and convenient information transfer?

It can be said that the information superhighway is a concept that keeps pace with the times, as long as this system can ensure that the information connected to the network can be transmitted quickly, it can be called the information superhighway.

Based on the current situation in Huaxia, Jiang Xinwei and they can completely expand and improve while building. At the beginning, lay one or two fiber optic cables, and then increase the number of fiber optic cables when the amount of information is large. Start with low-rate asynchronous optical transmission (PDH) equipment or systems to carry the transmission task, and wait for high-speed synchronous optical transmission (SDH) equipment and systems to be developed before topping.

As long as the carrying capacity of the information superhighway is ensured, it exceeds the information flow generated by society.

Although there is no urgency to develop high-speed and high-bandwidth synchronous optical transmission (SDH) equipment and systems, Jiang Xinwei still takes this matter very seriously, after all, this is his main business.

He is best at developing telecommunications equipment.

In order to develop high-speed and high-bandwidth synchronous optical transmission (SDH) equipment and systems, Jiang Xinwei put aside all other miscellaneous matters, and even ignored the inquiries of relevant departments about his other things. He worked with the scientific researchers of Feixun Group to formulate plans, draw schematic diagrams, and draw design drawings......

At the beginning, he proposed that the optical transmission rate must be above 10G, and multispectral multiplexing technology should be adopted.

Generally speaking, the optical fibers in long-distance optical cables transmit a single frequency of laser, and the transmission distance can be hundreds of kilometers. The so-called multispectral multiplexing is the transmission of multiple lasers of different frequencies in the same optical fiber, and the information transmission speed naturally multiplies. However, the laser transmitting sensor and the laser receiving sensor are correspondingly much more complex.

Jiang Xinwei developed this in his last life, and he is naturally familiar with the theory and principle, which makes the surrounding scientific researchers impressed.

However, the processing capacity of sensors and other electronic components was not good, and he had to work with everyone to modify the design from time to time to adapt to the microelectronics production capacity that could not keep up with his design level.

After a month of hard work with everyone, Jiang Xinwei had to leave his design post to deal with other things that had to be dealt with.

The first thing to deal with is Zheng Zitong's Chuncheng Automobile Co., Ltd., and he must understand and urge the company to design a good new car as soon as possible.

This is the order given to Jiang Xinwei by the big leader conveyed by Zhang Shuxian. The automotive sector is also an important part of the current WTO negotiations.

Jiang Xinwei felt a heavy responsibility and had to put down the research and development of SDH optical transmission and went to the northeast.

On the plane, he looked at the white clouds outside the porthole and sighed helplessly: "I'm just a small boss, and I'm being caught up in negotiations between countries? ”

I have to say that Zheng Zitong and others have done a lot of things, in just over a month, they have designed several sets of car style drawings, and also drew the corresponding engine compartment, as well as gearbox, clutch, air conditioning system, interior and so on design drawings and renderings.

They even made three sets of clay models.

However, after Jiang Xinwei looked at their drawings and clay models, he was a little disappointed, several sets of drawings did not have their own characteristics, and they basically referred to the old models before, which looked dull and did not have any aura.

However, the design of the mechanical part inside is not bad, after all, it is based on the engine provided by Shuangzhou Machinery Factory.

As a last resort, Jiang Xinwei took out the outline drawings of two sets of cars drawn on the plane last night and today.

When Zheng Zitong saw it, his eyes immediately lit up, and he said, "Jiang Dong, look at you, you are deliberately making me ugly." If you had come earlier, we would have designed according to your drawings. The shape of this car you designed is so beautiful, I want to buy it myself. Jiang Dong, let's not discuss it, just look at your drawings to design. ”

The design of a piece is not just a contour drawing, it must go through many steps, such as the most basic draft drawing, appearance rendering, body proportion calculation, interior space layout planning, and then re-drawing the design exterior drawing, drawing the design drawing, or making a clay model, and some also carry out wind tunnel simulation experiments.

Once these are all in order, start the data modeling, start calculating the structural strength of the main components, and start designing the structure of the main body parts. A prototype car is then made and embedded with chassis powertrain and interior modules.

After waiting for the prototype to be able to run and drive, various tests are carried out, test data is obtained, and modification and improvement are made according to the test data.

Jiang Xinwei asked a few designers around Zheng Zitong: "You look at the drawings I drew to see if it works, if it works, we will use this as a basis and start to enter the formal design." ”

He said this very conceitedly, and when he first heard it, he was a little domineering. But there is no way, he knows that now is not the time for himself to be modest and hypocritical, and if it drags on like this, he doesn't know how long it will take.

In fact, he knew that the drawings he drew were not rigorous and not beautiful, and Zheng Zitong and they should discuss and demonstrate. Even if a large international automobile company wants to design a new car, it is not something that can be decided in a month or two, and it needs to be demonstrated and discussed, but he really doesn't have time now, so he has to be overbearing and force them to accept it.

Besides, the drawings he drew were borrowed from the situation of several cars he bought in his previous life, and they were all borrowed from models that have not yet appeared, such as Ford Focus and Renault Symbol, which sold well in the previous life. At least it's a little better looking than the few cars on the market today, with more pop and modern elements.

It also makes sense to force them to accept.

Sure enough, after reading Jiang Xinwei's drawings, those technicians also expressed their approval.

Everyone started to get busy, and some people even took out their laptops and started designing with the special software for car design installed inside.

Jiang Xinwei was stunned for a moment and asked him, "How can you have such advanced design software?"
