This is the application technology of fiber-laser in communication transmission.

The communication channels provided by the optical fiber transmission equipment developed by this technology are extremely huge, and the two optical fibers can provide up to hundreds, thousands or even tens of thousands of communication circuits, that is, hundreds of people, thousands or even tens of thousands of people can talk at the same time, which is hundreds of times or thousands of times the capacity of the analog carrier!

Moreover, compared with carrier equipment, optical transmission equipment also has the advantages of small size, low energy consumption and low failure rate.

Jiang Xinwei crossed over, and naturally knew that the future transmission equipment must only be the world of optical transmission equipment.

In Jiang Xinwei's view, if we are fooled by a thriving foreign company, it may not matter if we suffer a small loss for the time being, and we will eventually be able to obtain a lot of benefits from the cooperation between the two sides, and may be able to improve the technical level of our technical personnel in the cooperation. But if we are fooled by such a bankrupt or bankrupt company, it will be too wronged.

"Can I stop the leaders here from being fooled by them? Can I get some benefit from this?" Thinking about it, he suddenly remembered another reason for the bankruptcy of this company in his previous life: the family members who held the real power of the company embezzled the company's scarce funds to invest in finance, and because of the wrong prediction, all the investment was lost.

Moreover, at that time, the teacher also said that the person who embezzled the company's funds invested in international crude oil futures: "Yes, international crude oil futures, this company really collapsed after the international crude oil price fluctuated violently!"

Thinking of this time node, Jiang Xinwei suddenly understood why the company did not go bankrupt: there are almost two months to live.

The fluctuation in international crude oil prices was caused by Iraq's invasion of Kuwait: Iraq's occupation of Kuwait, the world's leading oil-producing country, caused international oil prices to soar from $15 per barrel to $40 per barrel. However, two months later, when the Western countries led by the United States decided to use force against Iraq, international oil prices plummeted again, returning to about $15.

The sharp rise and fall in oil prices has bankrupted many crude oil futures speculators, including one of the owners of Etna Communications, who not only committed suicide by jumping off a building himself, but also took his last breath on the family business, which was already on the verge of bankruptcy.

……

Just as Jiang Xinwei was thinking, the speeches of the foreign guests had been going on for a long time.

Jiang Xinwei was even less interested in the content of the foreigner's current speech, because the content of the second young expert's speech was about the No. 7 signal—finally the same as what the host said.

Signaling is a commonly used professional term in communication, and it is simply the standard that regulates telephone conduction and transfer. Ordinary people don't need to know what it is, just know that there are two signaling in the communication field, "NO1 signaling" and "NO7 signaling", and know that the No. 7 signaling (NO7 signaling) is more advanced and advanced.

There are no two, three, or four in between...... Signaling, at least not used in telecommunications equipment in our country.

For others, the knowledge of No. 7 signaling is a new technology, but for Jiang Xinwei, it is completely pediatric, and he knows far more and understands the content than the foreigners who gave speeches on the rostrum.

At this time, Jiang Xinxu's only interest was that Leng Lan occasionally made a few translation errors in professional terms.

In all fairness, Leng Lan's English level is still very high, especially the pronunciation is very accurate. The mistakes she made in translation were because the foreign guest said that the No. 7 signaling was too professional, and it was not as specific a product as the carrier mentioned earlier, and many words could be translated by understanding and guessing.

She is only a science and engineering student, and she is not majoring in communication, whether it is professional knowledge, professional vocabulary or life experience, it is really difficult for her to translate such professional words, and it is rare for her to be able to translate to the current level.

If Jiang Xinwei hadn't come through time, if he hadn't been engaged in telecommunications equipment research for a long time, and if he hadn't been dealing with foreign businessmen or foreign experts for a long time, he would probably not have heard these mistakes. He was also sure that all the people in this auditorium who could hear her translation mistakes added up to less than a slap in the face, maybe a few university professors knew.

In fact, these mistakes she made have nothing to do with the big picture, because people who can't hear the mistakes won't delve into this field in the future, and it is enough to know a little common sense. And those who can hear the wrong thing can fully understand the original words of the foreign guest, and can ignore her translation.

Her crisp and mellow words echoed throughout the auditorium, and not only the male students stared at her with green eyes, but also the teachers, the leaders from outside, and the employees of the post and telecommunications bureau all looked at her with admiration, admiration, and even lust.

At this moment, Jiang Xinwei inadvertently noticed that the corners of the mouth of the foreigner who was giving a speech - Frankl - unconsciously twitched a few times, and then shook the speech without knowing it with a little irritability, and even glanced at Leng Lan who was translating his speech next to him, with a trace of impatience in his eyes.

Seeing his small actions, Jiang Xinwei, who had studied medicine with his father, couldn't help but smile softly: This guy has a desire to urinate and is anxious to go to the toilet.

"Go to the toilet, okay! Then I'll have a little exchange meeting with you in the toilet, hehe. Jiang Xinwei was still thinking about how to destroy the flickering of these foreign guests just now, but he didn't expect the opportunity to come so soon.

He got up from his seat and walked towards the back without hurrying.

Seeing him leave, Leng Lan, who was translating, stopped her mouth a little distracted, and looked at his back for a few seconds, until the principal sitting next to her coughed and reminded her, and she continued to translate just now. In order to finish it early, the Italian had already read the last paragraph in one breath, enough for Leng Lan to translate for a minute.

Jiang Xinwei went out and saw several security guards and two policemen standing in the corridor outside the auditorium. Several security guards did not react, but two police officers who had been at the school gate saw him and immediately walked towards him.

The thug who was with them didn't come in.

Jiang Xinwei smiled and waved his hand at the two policemen, and said loudly: "Wait a minute! I still have a little thing to do, and when I finish my business, I will take the initiative to go with you." ”

The policeman was stunned and both stopped. Several security guards also looked at him in surprise and wariness, wondering whether the boy, who was obviously a student, was a student of the school or a fugitive who had committed a crime.

Seeing that the policeman paused and walked forward, Jiang Xinwei shook his hand and said, "Don't be impulsive! There are foreign guests here, and I have made an appointment to meet foreign guests here." If you want to arrest me, if I shout, it won't do everyone any good, and it's not a good thing to have an international impact, right?"

A policeman said angrily: "If you dare to shout at us......"

Jiang Xinwei interrupted him and said sharply, "Stop...... Shhhh

The two policemen stopped again, but waited for a long time without moving, and just when they thought they had been deceived and hesitated whether to rush up quickly, grab him and drag him away, there was really footsteps in the auditorium.

Seeing that they not only did not enter but gently retreated, Jiang Xinwei smiled with an approving look.

Naturally, it was an Italian who came, and when he saw him come out, Jiang Xinwei moved half a step to the side.

When he looked at him, Jiang Xinxu greeted him with a smile in Italian: "Hey! Frankl, can I talk to you?" Originally, I admired the Luches family very much, but I didn't expect that there would be a liar like you in your family. ”

Frankl was amazed not only at the Italian-speaking young man he had met here, but also at the fact that he knew that he and his business belonged to the Luches family, and even more so at how much he called himself a liar.
