The era of telecommunication optical network has come to change the home to bring new life

Broadband has become an inseparable part of people's work and life. However, people still hear people complain: "How slow is the internet speed? Watching a high-definition video is just like this." A friend with IPTV in his home told me that home If someone watches IPTV and somebody else surfs the Internet, it will surely begin to quarrel, because one person certainly cannot use it smoothly. "The bandwidth is not enough."

Imagine if there is no upper limit on the bandwidth of the network accessed at home, even if all the appliances in the home need to be connected to the Internet at the same time, the smoothness is avoided. Is this scenario attractive? This is the last kilometer of a good life in the era of all-optical network. In fact, before the word "all optical network" was proposed, optical fiber has long been the protagonist in the field of long-distance communication. At present, the quartz fiber is used in the main cable of the communication cable. Most people now have broadband in their homes, which is copper broadband. The material used in this section from the base station to the user's home is copper. However, from the backbone network to the metropolitan area network, the two levels of networks have already completed the improvement of “light forward copper”. The rest of this distance, which is most closely related to the people, is the key to completing the “electro-optic network” to the “all-optical network.” It is also called the “last mile.”

“Do not underestimate this 'last kilometer'. The meaning contained here is very significant.” Zhu Baolong, optical fiber communications engineer of Fiberhome Communication Technology Co., Ltd., spoke of optical fiber communications, and his face was hard to hide his excitement. According to Mr. Zhu, the "last mile" used more advanced optical fiber than the main line. "To put it plainly, in fact, it is glass, its composition is the same as crystal, but its purity is even higher than that of crystal." The scene cut a section of fiber optic cable for reporters. It was originally only a fraction of the thick fiber optic cable of the copper cable. The protagonist who played the role of communication had only the thickness of the hair, and it was almost impossible to ignore it.

"It is such a fine thing that can increase the bandwidth to 100G." Mr. Zhu said that in fact, the bandwidth of optical fiber is endless, there is no ceiling. When you need it, you can add it up. Now we generally say that fiber-optic broadband can reach 100G, because experts have assessed that 100G is enough for use in recent years.

Small-scale devices have achieved triple-play convergence recently, and triple-play convergence is also a topic of great concern to the general public. Some people are concerned about what changes will come after the triple play, and some people are concerned about how such a huge project should be achieved. Zhu Baolong joked with reporters: "We have achieved triple play with a small device."

Mr. Zhu’s “small device” in his mouth is called ONU. Its appearance, size, and function are similar to those of the “cats” currently installed in everybody’s home. However, its function is much stronger than the "cat". Many home-installed broadband still need to rely on the telephone line, connect this "cat", and then connect the other end to the computer to access the Internet. In addition to connecting networks, this "cat" has no other purpose. The ONU is different. It has different output ports and can connect broadband, voice, and CATV radio and television. In other words, this small device can simultaneously connect to the Internet, telecommunication networks, and the wide network, which is what Mr. Zhu said "a small device has achieved triple play."

The light network changed the home décor. I remember talking about a fiber-optic broadband when chatting with a foreign friend half a month ago. He was very much looking forward to this. "I'm looking forward to FTTH, so that the internet speed is so fast that I There are a lot of things that can be done." But he also worried about a problem - from the current broadband to fiber-optic broadband, will not affect the layout of the home? This is also a problem that many people worry about? For this issue, the reporter specifically consulted Zhu Baolong, an optical fiber communications engineer.

It is understood that basically everybody now has a message box outside the door. Telephone lines, broadband lines, etc. coming in from outside will all be concentrated here. In the renovation of the house, these lines are arranged in the preset positions of each room according to the design drawings. In this way, when the optical fiber enters the home, it is relatively simple, as long as the copper cable from the base station to the information box can be changed into a fiber optic cable, and the lines in the home do not need to be changed.

There may be a lot of people who have doubts. They will ask: If I do not have this information box at home or the information box is not in the doorway but at home, what should I do? According to Zhu Baolong, this situation is relatively troublesome. If there is no information box, you can only change the open line, along the most inconspicuous corner of the road, where you need to install fiber. Although it will affect the appearance, but fortunately the fiber broadband line is relatively small. Another kind of information box at home is even more complicated. Because from the entrance of the house to the information box, it must be changed to fiber optics, and the pipes that were originally laid into the house are below the ground. If the age is long, the pipeline is damaged, and if it is pulled out and reinstalled, it is likely to damage the others. line. In this case, it was necessary to dig the ground and re-construct the ground.

"So ah, now if you are planning to decorate your house, besides considering the style of decoration, you should also remember to consider whether or not you need to install optical fiber." Zhu Baolong kindly reminded reporters that there are also need to remind friends here.

Light network brings new life Imagine, recently there are large films released, but the cinema is overcrowded, or at home to see it, turn on the computer, a few minutes to download a few G big high-definition movies; work overtime to leave the company at 9 o'clock in the evening, very Weary, really want to rush into the bathroom to take a shower, go out of the company, open the phone, remote control of the home's water heater to work; a sick at home, can not go to the hospital, turn on the computer and camera, connect the hospital's doctor remote guidance How to use drugs... Does this life make you feel very much aspire? Many people know that such a high-tech home is what Bill Gates has been trying to achieve. As an ordinary person, we can achieve the same with fiber broadband.

Another engineer of Fiberhome Communications Technology told reporters that the “home gateway” they are now working on is similar to Bill Gates’s smart home. The home gateway is similar to a web page, and all the home appliances in the background are connected to this web page. No matter where you are, as long as you log in to this page with your computer or mobile phone, you can send instructions to any home appliances. This can not help but think of another hot topic - the Internet of Things. "In fact, the ultimate realization of the Internet of Things also requires high-bandwidth fiber optic networks to provide support."

With fiber-optic broadband, you no longer have to worry about the speed at which IPTV will affect the computers in another room. If there are enough rooms at home, one room is open for IPTV, one room is for online video, one room is downloading high-definition movies and is still playing online games, and there are still people in the living room who use telemedicine. Take up bandwidth and affect speed.

The future is very beautiful, but it still needs to be achieved step by step. As more and more Internet appliances appear on the market, China Telecom has started to implement "light community" projects in Zhejiang Province. More and more people are beginning to realize that they need more bandwidth to realize information life. These phenomena all make us There is reason to believe that everyone’s home will be comparable to Bill Gates’ home in the near future.
