Chapter 1016 Hand-signed Opinion

Ignoring the slaps Lou Xiaoe gave him on the back, Gao Zhendong happily decided in his heart that this kid needs to be trained hard when he grows up! !

After having breakfast and saying goodbye to his family, Gao Zhendong got in the car and rushed to Beijing University of Technology. Today was Tuesday and he had classes.

As soon as he entered the office, a stack of new journals on the table caught his eye. There were domestic as well as foreign translations, but the foreign ones were usually published one or two months later.

Gao Zhendong was holding a copy of Laser, and he saw the article on laser gyroscope that was related to him. But he did not read it. He had read the article before it was published, and to be honest, it was not very informative. This was intentional by our comrades.

He continued to flip through it casually and said, "Huh?"

—— "Study on the feasibility of transmitting data using fully reflective optical fiber media."

Gao Zhendong is even very familiar with the author's unit, who is a comrade from the Northeast Institute of Optics.

At this time, the core + cladding structure of optical fiber has been determined, but its application in communication is still a long way off. The reason is very simple: the attenuation is too great.

With an attenuation of up to 1dB per meter, it is nothing short of a pipe dream to use optical fiber for long-distance communications.

Comrades from the Northeastern Institute of Optics still haven't solved this problem. They just discussed the feasibility of optical fiber data transmission and conducted data transmission tests using the lasers they had and optical fibers made according to foreign optical fiber technology.

The conclusion is - it can be transmitted, but the distance is limited and the bandwidth does not show any advantages for the time being, so it belongs to future technology.

However, at the end of the paper, they clearly proposed to invest more in this direction. After all, optical transmission has many advantages, such as large bandwidth, low interference, difficulty in stealing information, and the raw materials may be very cheap, etc.

This paper looks like a water paper, but it is not. Our comrades are now conducting research in this area at the highest level, and Northeast Institute of Optics is at the forefront in this regard.

Gao Zhendong thought about it and decided that since there were comrades willing to do this and suggested doing it, it would be easy to handle.

He picked up the magazine and wrote two lines on the heading of the article.

"This paper is forward-looking and practical in the fields of communications and laser applications, and its technology has broad application prospects. It is recommended to increase resources and conduct in-depth research."

"Gao Zhendong.1963.2.6"

Gao Zhendong called the staff assigned to him by Beijing University of Technology and asked them to send the magazine to the ministry in charge of science and technology.

"By the way, please get me another copy of this issue of Laser." Gao Zhendong reminded him. Firstly, he needed to read it, and secondly, his wife wanted to keep it. Lou Xiao'e attached great importance to all the results published by Gao Zhendong.

Now that gallium is about to be stably supplied from Qianshan, gallium arsenide semiconductor lasers have the possibility of practical application. With the addition of optical fiber, the information highway can be brought up. Even if it is not deployed on a large scale, at least the backbone network and military network can be used. Compared with other networks, this thing has obvious advantages.

"Fiber optic cables have no copper, so theft is useless"

"National defense optical cables, excavation is strictly prohibited"

"Boss, I dug up some military optical cables. Hurry up and get your passport and book a flight."

Gao Zhendong laughed out loud when he thought of the various optical cable jokes he had seen in his previous life.

When Gao Zhendong's hand-signed journal was delivered to the Academy of Science and Technology, the comrades there were delighted when they received it.

One comrade laughed and said, "We didn't have time to send him the surprises here, but he had already done the work."

Gao Zhendong’s spot is easy to secure, but the others will require a long period of discussion and communication.

Another person looked at what Gao Zhendong wrote in the journal, the name of the journal, and the content of the paper, and laughed: "He has such a high status in this area. Our surprises cannot reach him. He has a say in both fields."

Laser and communication, when these two are added together, there is really no one in the country who has more say than him.

"He has profound attainments in the application of lasers, and the theory and practice of communication technology. His judgments in this regard should be scientific and worthy of attention."

"I think so too. So, take a photo of his handwritten opinion, make a copy, and send it to the Northeast Optics Institute. The comrade from the Northeast Optics Institute will go to him and carry out further work."

Things that are hand-signed are effective, and signatures must be signed in person. When the comrades from the Northeast Institute of Optics received the opinions forwarded by the Academy of Science and Technology, they were completely confused.

That is, I just do some research and write a paper after work. How come I was noticed by the top domestic laser expert?
This comrade did not have much dealings with Gao Zhendong and was not responsible for the optical system of the lithography machine, but he had heard of Gao Zhendong and had seen him from afar.

Taking the photocopy, he went to the director to report his work with joy and confusion.

When the director heard what he said, he immediately stretched out his hand with some excitement.

"Hey, Lao Chai, that's great! You have good luck, skills and vision. Give it here, let me see it!" The director had dealt with Gao Zhendong before, and the fused quartz optical glass here was made with the technology provided by Gao Zhendong.

"Wow, Chief Engineer Gao's handwriting is so vigorous and powerful!" The director was very excited after reading the forwarded photocopy and the opinions of the Academy of Science and Technology and the science and technology authorities.

"Hey, I told you to do more research and publish more articles. Look, here comes the research topic! And I think this is not a simple thing, and it has a wide range of application prospects."

Although Gao Zhendong came here before to ask Dongguan Institute to help make the optical system of the lithography machine, the technology they have is top-notch, and their status in the field of lasers is needless to say.

With him personally endorsing the technology and specifically requiring in-depth research, what else could be wrong?
"Do you have any important projects on hand? Even if you do, hand them over to other comrades first. Hurry up and pack up and go to the capital to visit Comrade Gao Zhendong as quickly as possible."

"This..." Chai Gong hesitated.

"Don't worry, I won't cheat you. No matter what projects you have on hand, none of them are as promising as this one. It's an opportunity that others can't even ask for, so don't hesitate. If you don't go, I'll find someone else. Hahaha." The director laughed, with an expression that said, "If you're not good enough, I'll find someone else if I give you a chance."

Chai Gong finally reacted. Yes, it is better to be the head of a chicken than the tail of a phoenix. What's the point of following others? Wouldn't it be great to have your own project?
Besides, a topic that Comrade Gao Zhendong, the Academy of Science and Technology, and the competent authorities all valued so much, couldn't it be a small chicken? It must be a big phoenix!

"No, no, no, I'll go and take over and prepare right away."
-
During the time when the firewood workers were handing over and cleaning up, Gao Zhendong received an invitation from the Defense Working Committee. The troops had already compiled and sorted out the experience and expectations of intelligence distribution and even the command system in the battle against Zang-San, and hoped that the relevant professional and technical personnel could discuss this matter with their comrades in the army.

Gao Zhendong gladly attended the meeting. In fact, both he and the Defense Work Committee had been considering and planning this matter for a long time, but the initial conditions had not been mature.

The means of communication is one aspect, and the ideas of the troops are another.

For the troops, they have no relevant experience and have never truly experienced command and combat under network and information conditions. Many of their own requirements are simply unclear, and they cannot express what kind of command system they want.

Through the battle against Zang San, they had initially tasted the sweetness of integrated command, and naturally had more ideas and expectations. In addition, with the efforts of the Military Communications Institute, the Postal Communications Committee, Gao Zhendong and other parties, the military digital communication system also made initial progress.

In this case, there is a basis for discussion on this matter.

Almost everyone sitting in the meeting room was an acquaintance. As Gao Zhendong continued to work hard in this area, more and more people in the military system knew him. Especially the comrades from the Military Communications Institute, when they saw him, they would first call him Teacher Gao before sitting down.

At the beginning of the meeting, the first question raised by the comrades in the army, which is also the first question that the comrades in the Military Communications Institute are racking their brains over now, is the issue of the communications network.

"…Based on our current experience, our biggest problem is the lack of a communication network that can effectively self-organize and self-manage, which is particularly evident in combat…"

The leader of the Defense Work Committee was a little confused: "Communication network? Your current communication equipment can communicate with each other, right? Is there any obstacle in the middle?"

The comrade from the Military Communications Institute nodded and said, "Yes, point-to-point communication, when both parties can connect directly, the problem is not prominent at this time. We only need to deal with channel conflicts and blockages. However, this also has hidden dangers. When a large number of communication terminals communicate in the same channel, such conflicts and blockages will almost deteriorate to the point where communication is impossible. A large number of communication terminals may fall into endless reconnection and waiting."

To give a simple example, when two people call the same person at the same time, they can also complete the waiting and calling through tacit understanding, convention, random delay, channel occupancy monitoring, etc., and finally complete the communication.

However, when ten or even a hundred people call the same person at the same time, the situation worsens. It is possible that all terminals initiating calls will fill up the communication resources of the called terminal just during the calling process.

This does not take into account the situation where everyone is on the same channel, directly blocking the channel.

"Comrade Zhendong, what do you think about this matter?" The chief engineer of the Defense Work Committee directly called out Gao Zhendong.

Gao Zhendong looked up from his notebook. "I have an idea, but it involves a lot of things. It's not very meaningful to talk about it in bits and pieces now. And I guess channel blocking is not the biggest problem they encountered. I'll talk about it later."

The comrades at the Military Communications Institute were impressed by Gao Zhendong's guess: "Chief Engineer Gao is right. The biggest problem is still the routing and forwarding of information."
