Chapter 761: Research and development of high-speed optical transmission

Wen Nianshi snorted dissatisfiedly at his father's back, and then said to Jiang Xinwei: "Xinwei, since you have no opinion, then we will leave for the filming base tomorrow." Do you have time to come and see us?"

Wen Niange interjected again: "You think Boss Jiang is you, he has a body." A man goes to see a group of women filming, and he's embarrassed to go?"

Wen Nianshi turned around dissatisfiedly and said to her brother: "Brother, you interjected again this time, right? How do you know that Xinwei can't spare time? This TV series is also invested by him, which is the same as his investment in other companies and other products." ”

Wen Niange said: "Joke. Investing in TV dramas, cars, telecommunications, ...... How can it be the same as investing in high-tech?"

Wen Nianshi said without backing down: "How is it different? Maybe the investment in this TV series is more profitable than investing in those high-tech." …… , brother, do you dare to bet?"

That night, Jiang Xinwei did not stay at Wen's house, but stayed in a hotel not far from Zhonghua Software Technology Company. After staying here, he called Su Dingyu.

Su Dingyu threw down the work at hand and hurriedly met with Jiang Xinwei, in the room, the two discussed the construction of the information superhighway and the upgrade of Lala's software, and the two also talked about Jiang Xiaoqing's company.

This chat lasted until more than three o'clock in the morning, and then they rested.

Early the next morning, Jiang Xinwei took his bodyguards and flew to Shuangzhou Power Machinery Factory in Shuangzhou City on his own special plane.

Because they knew that Jiang Xinwei was coming over this morning, Zhang Huan and others arranged for experts to discuss the design of the tank.

After welcoming Jiang Xinwei into the confidential conference room, everyone continued with the discussion they had been having.

A former Soviet expert said: "Our engines are up to 1,800 horsepower, which is the best in the world, and we can and should increase the caliber of our guns." In my opinion, we can completely learn from the American M551 tank, which uses a 152 mm caliber gun, which can fire both shells and missiles. ”

An Italian expert said: "But don't forget, the American M551 tank is a light tank. And the tank was not successful, it was discontinued after only ten years of equipping. ”

"But it also produced more than 1,700 vehicles," said the Soviet expert. Besides, I'm talking about the caliber of artillery, not anything else. The problem was the engine transmission, suspension and flammable cartridges. ”

Zhang Huan said: "There is no need to make such a large caliber, right? The power of artillery is not only related to caliber. ”

The former Soviet expert shrugged his shoulders and said: "Well, I'll be honest, we in the Soviet Union have previously studied tank guns with a caliber of 152 mm and a diameter of 55 times. One shot can penetrate two American M1 tanks!"

In the end, everyone unanimously agreed to adopt the mainstream caliber artillery of the world's heavy tanks, that is, a 125 mm smoothbore gun with a diameter of 70 times. An automatic loading system is adopted, equipped with a remotely controlled unmanned turret. The automatic fire control system was arranged in a manned compartment. Weapons, ammunition, turret and artillery aiming power drives, commander-in-command and gunner-sighting systems, all of which have been moved out of manned compartments.

After discussing the artillery and gun sighting system, everyone also discussed the chassis and turret shape of the tank, and then discussed the main armor.

Some experts propose to develop reactive armor, some people think that ceramic composite armor should be used, others think that this tank is mainly exported, there is no need to make the cost too high, simply follow the homogeneous special steel plate, anyway, the tank engine is powerful, and it is okay to increase the weight of some armor.

Next, the discussion was about the digital computer, hydraulic transmission system and image-stabilized fire control system required for the tank.

Jiang Xinwei was just a pseudo-military fan in his last life, and he only knew some simple data about tanks or something, and he couldn't even say anything about it. However, he did not sit in on the discussion all the time, but also participated in the discussion, and from time to time he said some parameters of the American M1 tank, the German Leopard 2 tank, and the French Leclerc tank that he remembered.

For example, the American M1 tank 1500 horsepower weighs 62 tons, the road speed is 65 highways per hour, the maximum road travel is 495 kilometers, and the 120mm smoothbore gun. It can fire tail stabilized deshelling armor-piercing shells, armor-piercing shells and grenades, of which armor-piercing shells can penetrate 850 mm of homogeneous steel armor at a distance of 2000 meters.

Other experts were not surprised that Jiang Xinwei was able to get these data at his fingertips, in their opinion, since the military gave Jiang Xinwei the task of developing tanks, they must have told some data on tanks in other countries.

Although this time it was only a cursory discussion of the tank's data, styling and some basic parameters, what I did not expect was that this discussion would last for two days.

Military experts were also invited to participate.

The military experts who participated in the discussion were excited and a little unconvinced, and did not believe that the Shuangzhou Machinery Factory could develop a tank with those parameters they marked, and if it could really be developed, it would crush the tanks currently equipped by the domestic military, and even the 99 tank might not be able to surpass it.

After setting the rough parameters, Jiang Xinwei did not stay in this machinery factory any longer. Because he knew that he didn't know anything about tank building, and that the refinement of those rough parameters had to be done by experts in the field, and he couldn't help a little here.

He first went to Xinlan Building to find Leng Lan, the general manager of Taishan Investment Company, first listened to her report on the establishment of an investment company, and then discussed relevant investment matters. Then she left in her resentful gaze and headed for Zi'an City.

He participated in the research and development of high-speed, high-bandwidth multiplexed synchronous optical transmission equipment (SDH) at Feixun Group.

Optical transmission equipment has changed rapidly in recent years, and a few years ago there were only asynchronous optical transmission devices (PDH), and the speed was not high, many were 140 megabytes. But now optical transmission equipment has suddenly developed into synchronous optical transmission (SDH) equipment, and the rate has increased thousands of times and tens of thousands of times.

At present, SDH is used to form the backbone optical transmission network in the world. Some large-scale private networks also use SDH technology to set up SDH optical loops inside the system to carry various services.

The reason why SDH transmission equipment and systems have developed rapidly is mainly because SDH transmission systems have a unified frame structure in the world, digital transmission standard rates and standard optical path interfaces, so that the network management system can communicate with each other, so it has good horizontal compatibility, it can be fully compatible with the existing old PDH equipment and systems, and accommodate a variety of new business signals, forming a global unified digital transmission system standard, improving the reliability and applicability of the network.

At the same time, because SDH has a variety of network topologies, the network it composed of is very flexible, it can enhance the network monitoring, operation management and automatic configuration functions, optimize the network performance, but also make the network operation flexible, safe and reliable, so that the network functions are very complete and diversified.
