Chapter 1065 Preparation and Testing

Then he saw a number that stunned him: "Information capacity 1GHz?"

1GHz and 1Gbps are not the same, but for Chai Gong, this is the most intuitive idea. If 1Gbps is the speed of Gigabit Internet in a few decades, which will be available everywhere in every household, then for him now, it is a bit like Bill Gate's evaluation of 640kB memory.

It can't be used up, it can't be used up at all.

The shock this intuitive number gave him was just like 1000 million cash placed in front of an ordinary person, with a strong impact.

Now he understood why Chief Engineer Gao was personally concerned about optical fiber, and even appointed him as the general because of his immature paper.

The temptation is too great!

Gao Zhendong smiled and shook his head when he heard his words: "It may not be possible now, but the potential in the future is far more than this. You can just digest and absorb this, and don't worry about having to do it now. The key is to first solve the problem of mode stability, dispersion and power control."

Only then did Engineer Chai understand why Chief Engineer Gao said last time that things were not that simple and that there were still many problems to be solved. If Chief Engineer Gao was not involved in this matter, it would be full of pitfalls.

"Okay, okay, Chief Engineer Gao, we will start studying and digesting this information when we get back." Engineer Chai did not feel depressed at all. Instead, he felt excited as if he had seen a new world.

"Do you need a teacher?"

"No, no, we will go back and ask our comrades from Northeast Polytechnic University to explain it to us. If there is still something we don't understand, we will ask you again. Otherwise, it will waste too much of your time." Chai Gong was very methodical in arranging his work.

Gao Zhendong nodded. This arrangement was not bad.

He reached out and began to rummage in the drawer again. The rustling sound made the woodcutter itchy and he really wanted to see what was in the drawer.

Chai Gong didn't have any extraordinary ideas. He was just a technician and was curious about technology.

His torture soon ended as Gao Zhendong took out another set of materials.

"That one is for you to learn the theory, but you can't just learn the theory. You still have to go hand in hand with the actual implementation. This is the practical work you will do next."

Mr. Chai took the materials from Gao Zhendong with surprise. There were only two chapters on it.

The first one is "Optical Fiber Preparation".

This made Chai Gong feel surprised but also disappointed. Since this thing had already been done, there was nothing else for us to do.

But after a closer look, he felt a mixture of worry and happiness. He almost wanted to slap himself in the face, what's wrong with you?

This part of the material does not mention any specific details about optical fiber manufacturing, but only theoretically analyzes some manufacturing boundary conditions, such as the ratio of the outer and inner dimensions of the cladding and the inner core, possible tensile strength, etc.

But what made him most happy was that this part, through calculations, revealed the problem he was most worried about: dimensional tolerance.

The diameter of optical fiber is very small. At this scale, it becomes very difficult to control the dimensional tolerance. However, this part of the research solves a problem.

——Through theoretical analysis and calculation, as the fiber diameter decreases, the dimensional tolerance becomes less critical.

Just this one sentence can save a lot of hair on the heads of comrades in charge of optical fiber manufacturing technology!
There is no need to deliberately control the tolerance within a strict range, but anyone who is engaged in manufacturing technology knows what this means.

What is guidance? What is leading the way? This is it!

"Chief Engineer Gao, is the conclusion of this dimensional tolerance true?" It's not that he didn't believe Gao Zhendong, but he didn't believe his own eyes and had to verify it.

Gao Zhendong nodded and smiled. Comrade is still very rigorous and does not blindly follow authority, so he also leaves room for maneuver in what he says: "This is the theoretical calculation. You will know if you try it in your work, hahahaha."

He hopes that his comrades will maintain the necessary vigilance against the sources of technology.

"Okay, okay, we'll pay attention to this." Chai Gong agreed excitedly and turned his attention to the last part.

——“Experimental research”.

This part is the design of some experiments, including electromagnetic experiments and optical experiments.

It is not complicated, but it directly points out what test to do and what materials or equipment can be used. There are no details, but it is instructive enough.

This thing, like the optical fiber preparation just now, is a treasure to Chai Gong, as it can greatly reduce their experimental workload.

Those who study physics know that experimental design was very important in the early stages of the development of physics. A flash of inspiration in an experimental design could solve a major problem - such as how to measure the speed of light.

He quickly glanced through it and assured Gao Zhendong: "Chief Engineer Gao, with these things, I am more confident. I will go back and start the relevant work!" Whether the iron impurities are removed or not has no effect on the research on optical fiber preparation. More or less iron will affect the transmission quality, but it has almost no effect on the physical properties of the optical fiber itself.

Now he has completed the research on inherent transmission loss, and Chief Engineer Gao helped him complete the research on electromagnetic properties. He also provided some key points in optical fiber preparation to avoid some pitfalls, and also designed some of the most core experiments.

If he can't produce any results, the woodcutter himself will feel like a waste.

Gao Zhendong nodded: "Well, you should pay attention to these later experiments. As long as the test results meet the basic requirements above and have a full set of data, they can be combined with the previous two parts of the research to write a paper. This has no direct relationship with whether the optical fiber that meets the requirements of long-distance communication is prepared or not."

A paper is a paper, and optical fiber is optical fiber. After the paper came out, it took a lot of time to produce an optical fiber that can be used actually.

"Okay, Mr. Gao, I will pay attention to the arrangements of the work." It sounds like Chief Engineer Gao has high requirements on the time required for the thesis?
This aspect must be very advanced. If you work on it for a few years, it will be meaningless. The reason why Gao Zhendong wants to publish this paper publicly is that even if he keeps it secret, it will be published in a few years. There is no point in hiding it.

"Okay, if you lack anything in your work or encounter any difficulties, feel free to contact me." Gao Zhendong joined the Department of Mathematics, Physics and Chemistry of the National Academy of Science and Technology, which made it much easier for him to allocate resources.

Especially some instruments and equipment, which Dongguan Institute may not have.

Chai Gong expressed his gratitude again, then prepared to leave the third factory and say goodbye to Gao Zhendong.

"Don't worry, I can't have dinner with you, but I'll arrange for a comrade from the Third Factory Office to accompany you. You have to have a meal anyway."

"No, no, Chief Engineer Gao, to be honest, I don't have much time this time. I have to go buy some things for my wife and children at home, such as tape recorders and electronic watches. It's not easy to buy them over there."

He was not being polite and refusing, he really wanted to buy it. It was true that Northeast China was the big brother these days and had everything, but some new and rare things were really not easy to get.

There were things like tape recorders and electronic watches in the Northeast, but they were often hard to come by, and he didn't have enough industrial tickets. He heard that there was a place in Beijing where he could buy them without tickets, but he had to trade in foreign exchange coupons or buy them through foreign comrades, so he decided to try his luck.

Gao Zhendong understood roughly as soon as he heard it: "Is that so...do you have enough tickets?"

"Ah... enough, enough!" Gao Zhendong saw the hesitation for a moment very clearly.

"Wait a minute!" Gao Zhendong took a piece of paper from the table, wrote a note with a pen and handed it to Chai Gong.

"Take this thing and go to the comrades at the Computer Equipment Research Institute of the 1201 Factory of the th Ministry of Machine Building. They will arrange whatever you want. You won't save a penny, but you will probably save a lot of trouble."

This is a comrade who is responsible for an important scientific research project. It is a big deal to lend a hand. He doesn't even try to avoid it.

The reason why Chai Gong was asked to find the Computer Equipment Research Institute of Factory 1201 was because Chai Gong did not know how to use this note or who to find, but the people at the Computer Equipment Research Institute knew and would naturally make arrangements.

The reason why he didn't ask the Institute of Computing Technology for help was that he felt that the Institute of Computer Equipment was his territory, and he was embarrassed to ask the comrades in the Institute of Computing Technology for help.

Gao Zhendong didn't explain much, which confused Chai Gong. Who should I go to with this thing? You didn't even say that.

However, with the note in his hand, he honestly asked for directions all the way to Factory 1201. Chief Engineer Gao must have his reasons for saying so.

When he handed the note in his hand to the security guard of the Computer Equipment Research Institute of Factory 1201 with a bit of confusion and uneasiness, the security guard glanced at it, immediately widened his eyes, glanced again, and picked up the phone.

"Please wait a moment. I'll find someone." Then he said to the phone that was immediately connected: "Director Gao..."

Huh? The director here is also surnamed Gao?
-
In a laboratory at Lou Xiao'e's school, a researcher opened a cabinet containing cultured Klebsiella.

This strain of bacteria can produce β-lactamase, and penicillin is ineffective against it. So even though the culture medium in these culture dishes contains penicillin, Klebsiella still grows unrestrainedly all over the culture dishes.

It was another fruitless day. The researchers carefully observed each sample and habitually complained in their hearts.

But she didn't care. This kind of work is like looking for a needle in a haystack. One has to be able to endure loneliness and failure. There are only a few batches, and if one can't stand such a short time, then she'd better stop doing this.

Suddenly, she stopped moving and stared at a petri dish.

There are several small holes in the culture dish, and the surrounding area is clean, revealing the culture medium base with a slightly light brown color.

She rubbed her eyes and looked over again.

That's right, no!
She was startled, turned around and ran out, shouting as she ran.

"Professor Qi! Senior Sister Lou! She's gone! She's gone!"
