Chapter 699 Decision (Second update)

PS: The 10,000-word update is over today. I wish everyone a happy May Day holiday and will continue the 10,000-word update tomorrow.

The next day Liu Hai met Ni Nan at Fenghuo Technology Company. Liu Hai had read the relevant information yesterday, but Liu Hai was not satisfied with what the information said.

"I have read the information you gave yesterday. Is there any way to further improve the transmission rate of optical fiber?" Liu Hai started this project to promote the development of domestic semiconductor technology. Liu Hai would definitely not be satisfied simply using the existing optical fiber technology. After all, it’s such a big investment.

"This is difficult, especially in terms of our domestic optical fiber manufacturing technology. If we introduce foreign technology and research talents, we should be able to improve it again." Ni Nan answered after hearing Liu Hai's words.

"There are also modulators and other things. After all, it is such a big project." Liu Hai asked again.

"All main lines use optical fiber. I personally think there is no problem at all. However, if the boss wants more information, he needs more professional investigation and research." Ni Nan felt a little guilty when he said this, because he submitted it to the boss yesterday The information is mainly my own personal opinions.

To replace the cable solution with an optical cable solution, the technical standards, related training, and upstream and downstream related industries involved are a very complex system.

Before the boss spoke, Ni Nan could not produce a more professional result, because this was not something that could be decided by one person, and he needed to find technicians in related fields to demonstrate.

"Then you should investigate first and make a solution for replacing optical cables with optical cables. Our purpose is to promote the development of semiconductors, not to make do with existing technologies. When formulating technical standards, we might as well make them a little higher. A little bit." Liu Hai reiterated his thoughts.

"Boss, I propose to build an optical fiber network within Eastern University of Heavy Industry for testing." Ni Nan proposed an idea.

"This will become the world's largest fiber optic network application system in the future, which will allow us to accumulate a lot of experience for our future promotion in other countries around the world." Ni Nan said again.

"In addition, you should also find someone to sort out the patents and technologies in optical fiber communication. You must buy any licenses that should be purchased abroad, especially the basic ones. Otherwise, we will easily get stuck when we develop." Liu Hai said again.

"In addition, when making this plan, try to replace it with related domestic products. If the domestic products are really not enough, we can buy imported ones. Of course, we can license the technology, or even buy them back and produce them ourselves." Liu Hai nodded and added.

"I will come up with a detailed plan to the boss as soon as possible!"

"You don't have to worry about investment. If you can get a fiber optic network, just get a fiber optic network." Of course Liu Hai knows that the future development direction is the fiber optic network, and he will definitely do it if he can get it now.

"Yeah!" Liu Hai nodded. Anyway, the 386 chip was not launched by Intel until 1985.

"Okay, boss." When Ni Nan heard Liu Hai say this, he knew that the boss had decided to replace the cable plan.

"I can only say that the laboratory is working hard on research and development!" Ni Nan is a technical talent. Hearing Liu Hai ask this question, he answered like this.

At the same time, I secretly made up my mind that when I go back, I must urge the guys in the chip laboratory. After all, the boss is buying chip architecture licenses and technology. If the boss is willing to spend money, everyone must be willing to risk their lives.

Even a 50% increase in investment or more bangs are acceptable.

"Of course, including the equipped computers, these can all be included in the budget."

Of course, the cable solution also has many advantages. First of all, the solution is mature and can be laid on a large scale and quickly. The construction process is not as complicated as optical fiber.

This is equivalent to us skipping the cable network step and going directly to the optical fiber network.

It would be better if we can develop it first during this period. If we cannot develop it first, then we will have no choice but to purchase a technology license.

Although it is unlikely that things will be stolen on the railway, it is not uncommon.

Optical fiber networks have many advantages. First, they have high transmission rates, low power consumption, and last but not least, they are not afraid of theft.

The cables are all copper.

"In its implementation stage, it seems that the transmission rate of the cable is sufficient, but considering future development, I personally think that the future of optical cable is better."

"In addition, about the parameters of the computer chip I mentioned to you last time, how long will it take to produce the finished product?" The computer chip Liu Hai mentioned last time was the classic 386 chip.

Of course, there are also disadvantages, that is, it consumes a lot of power, there is a risk of being stolen, and there is also the issue of updates and iterations.

"Well, the project plan is a little more detailed, including technical training, construction training, etc."

"Understood, boss." Ni Nan left after saying this. He originally thought that the boss would let him talk more, but he didn't expect that the boss would only ask these few questions. It was a pity that he had prepared a lot of materials.

At the same time, I was relieved, because the boss was not an expert. From a purely cost perspective, using cables was the most cost-effective, and the laying speed was also the fastest, because everything was ready-made.

There are still many technical problems with optical cables. When laying the network, the progress may not be that fast, because some problems may not be discovered until large-scale applications.

Optical cables are currently only experimental in foreign countries and are also experimental in China.

The most important thing is that Ni Nan is afraid that the investment in the optical cable project will be too large and the boss will not have that much money.

If Ni Nan knew that Liu Hai still had hundreds of millions of dollars in funds, he probably wouldn't be so worried.

If I knew that bangs could earn more than 10 billion US dollars a year, I would probably have bolder ideas.

The reason why Liu Hai didn't ask about the detailed technical aspects was because he didn't know much about it, and there were already related instructions in yesterday's information.

Of course, the most important thing is that Liu Hai knows the general direction of the future. Although optical cables are facing many difficulties now, once a breakthrough is made, we will be at the forefront.

Just like our country's phased array radar jumped directly to active phased array radar.

As for the Bald Eagle, due to technological development, the phased array radar was directly introduced first, but how to say this thing, it is impossible to eliminate this product after three or two years of production this year.

Congress will definitely not agree to such a plan. At any rate, it will take a few more years to decide. This will cause the Bald Eagle to lag behind us in terms of active phased array radar technology.

Of course, we also experienced many difficulties when we directly introduced active phased array radar.

But by the time Liu Hai crossed over, small active phased array radars were already being used to monitor wild animals damaging crops, but what about more advanced military models?

Liu Hai has no doubt that in the future, individual soldiers will be able to carry active phased array radars, so that in the future people will really become clairvoyant and obedient.

Liu Hai also left FiberHome Technology Company after Ni Nan left. Regarding the general management of this company, Liu Hai had no control at all, only the R&D department.

Anyway, this company is also a confidential company, and there is almost no chance for someone to get involved in it. If anyone wants to do something in it, there will be serious consequences waiting for them.

Liu Hai is not worried at all about the development of semiconductors in our country. He invests hundreds of millions of dollars every year. If he cannot stimulate this industry, it will be impossible.

During this period in history, let alone hundreds of millions of dollars invested in the semiconductor field, how much were the entire foreign exchange reserves?
Back in the factory, Liu Hai came to the telex laboratory of the private jet. The fly-by-wire control system consists of a steering column and a force-sensitive sensor, various input signals and feedback sensors, a flight control computer, a servo steering gear and a booster.

This is also closely related to semiconductors, because if you want to know the current status of the aircraft, you need to apply sensors on a large scale.

To put it bluntly, it is to let the pilot understand what the attitude of the aircraft is now and what attitude it will take when operating it by himself.

Of course, the fly-by-wire system is not omnipotent, and the fly-by-wire system will also be subject to interference and sensor failure.

When it comes to sensor failure, the biggest loss is the Bald Eagle's B2 bomber. Because the sensor is wet due to rain, the data transmitted by the sensor is incorrect, which then causes attitude control errors during operation and eventually crashes.

Therefore, to avoid this kind of error, the telex system is not a single channel, but has two redundancies, three redundancies or even four redundancies.

The earliest civil aviation passenger aircraft was the Airbus A320, which adopted fly-by-wire flight control and a statically unstable design.

It has a flight control system composed of 7 computers, including 2 elevator/flap computers, 3 spoiler/elevator computers and 2 flight stability computers.

When Liu Hai traveled through, the optical fiber transmission system was already more resistant to interference than the telex system.

Liu Hai plans to make this telex laboratory bigger and stronger, because this is the future development trend.

Start with small private jets and then gradually expand to other aircraft.

This will prevent you from taking too big a step and pulling your eggs.

Of course, the current fly-by-wire system is only in the laboratory, and it will continue to be tested and optimized after it is put on the plane.

Because the laboratory can only simulate flight postures, complete experimental data can only be obtained by flying in the sky.

The reason why you need to back up a hydraulic control system is because you don’t know whether there will be bugs in this telex system, because bugs only appear under various conditions, so no one knows what’s going on in this telex system. Days later, will there be bugs due to various chances and coincidences?

Some of the air crashes that occurred in history were all caused by system problems. System bugs only appeared due to the combination of man-made or natural conditions.

When the earliest commercial airliners used fly-by-wire systems, they also had backup mechanical control systems.

Even if Liu Hai simulates relevant data through the software system of the aircraft carrier space, it cannot be said to be completely correct. Experiments and applications are always slightly different.

Liu Hai returned to the courtyard in the evening, and the people in the courtyard were not surprised by Liu Hai's return. Liu Hai would come back every now and then.

Liu Hai came to the basement, and then entered the aircraft carrier space. He took out the novel and read it, taking notes while reading, such as the technology related to coenzyme 10.

"Not to mention, this is much better than reading a paper!" Liu Hai read happily while copying.

Because the timeline in the novel is 82, Liu Hai was not anxious at all.

Moreover, this novel cites a lot of paper data, which will allow Liu Hai to know which papers to look for when giving directions to junior sister in the future.

It's much better than Liu Hai looking through those papers, magazines, and medical books.

"Junior sister will take this path from now on!" Liu Hai laughed in his heart, and he will not give any other guidance to junior sister in the future. It is enough to follow the contents of this novel and guide junior sister the way.

I read the novel for several hours and summarized a lot of things. Liu Hai saw that these things were no longer enough for his junior sister to use for several years, so he decided to stop reading.

"The next step is to continue to dismantle the Hornet!" Liu Hai prepared to dismantle the Hornet carrier-based aircraft.

Of course, Liu Hai mainly works on the hardware system. As for the software system, we will take our time.

After leaving the aircraft carrier space, Liu Hai stretched.

When Liu Hai was stretching in the basement, in a base of Fat Bear in Tocharo, a man was smoking and drinking in front of the radar screen.

It's hard for everyone to relax during the day, because once night comes, it's hard to get a good night's sleep inside the base.

At night, there was either the sound of sniper rifles or the disgusting sound of gasoline engines flying across the sky.

However, with the continuous high-intensity blockade of the border by Fat Bear, the sound of dozens of flying motorcycles could be heard every night in the past, but now you can basically only hear one or two a night.

But the damn sniper rifles are ringing again, those damn guerrillas, they will shoot everything they can see with sniper rifles from far away.

Once this kind of sniper rifle fires, everyone gets down quickly, because once they are hit, it is over.

Suddenly, the radar soldier saw a bright light flash on the display screen and was so frightened that he dropped the cigarette in his hand.

He quickly picked up the phone: "Bakilov, did you hear anything?"

The radar soldiers called the observation post 15 kilometers away. In order to deal with the attack by the scooters, Fat Bear set up observation posts around the base. When these observation posts heard the sound of the scooters flying in the air, they would give the base an early warning.

"Andre, are you drunk? If there was a sound, I would have called you. There is no sound in this damn sky." At the observation post 15 kilometers away, Bakilov was bored. Hiding inside the outpost of the concrete building.

To be precise, this concrete post is like an underground bunker. There are many sandbags piled around it, almost completely covering up the entire post.

Because those damn guerrillas had RPGs, rifle grenades, and even heavy sniper rifles. Fortunately, the observation post was on a steep mountain. Even so, these soldiers did not dare to take the lead and could only observe the surrounding situation at any time through the periscope.

"Well, maybe there's something wrong with my old friend." Andri saw that the signal on the radar was completely different from the previous signal characteristics of the flying motorcycle, so he turned off the radar and then restarted it.

"Andre, don't finish the wine. Wait until I come back from my shift. If there is no wine, I will crush your balls." The soldier at the observation post was still teasing on the phone.

"Haha, you deserve it. There is no alcohol in this damn place." Andre laughed.

"Oh, it's damn broken." Andre chatted with the other party and waited for the radar to turn on again, but when the radar turned on, Andre slapped his forehead.

Because there are a bunch of light spots on it, and the direction of the light spots is the direction of the observation post that is calling me. If there are really so many flying motorcycles, I can hear the sound in the microphone.

Since there is no sound, the problem must be with this radar.
