Beijing unicom implement 100% optical fiber door in five years by Marry
Download capacity up to several G’s “file” need dozens of seconds a few seconds, even the will no longer is a dream. This week, Beijing unicom announced that by the end of this year will ensure the family to realize “fiber optic door”. The next five years, Beijing unicom plans to 100% of the fiber to the home, can provide for home users BaiZhao bandwidth and to provide enterprises with WanZhao bandwidth access ability.
Widen network “last mile”
For the growing size of the network, the most difficult to stand for: the so-called “broadband” rate is only a few hundred K even dozens of K. For many broadband users, operators in advertising description of the “directly read online hd large, download movies just a mouse, by mobile phone remote control home appliance” digital life or a dream.
However, the dream is becomes a reality. 26 September morning, with continuation school for overseas Chinese central switch stop working, Beijing’s residents near the market of thirteen thousand, on copper said goodbye to The Times, walked into life yuli. This is also the light into the important engineering project copper back one. “Fiber optic door let network speed has been significantly improved, not only unit, send a picture file is very fast, and see movies at home, download the files also no longer” card “. In the work of the department of China near qing said.
According to information, the past copper broadband use in data transmission, a speed of the loss of problems, especially from home to communications company bureau end more than 1.5 km, broadband speed decreased obviously. This is because copper cable will interfere with optical fiber transmission, and in addition to the characteristics of the speed, the basic from the transmission distance influence, the more won’t be in the process of transmission by electromagnetic interference. In addition, the traditional theory of copper transmission rate can reach 8 Mb/s, but the actual transmission generally less than 2 Mb/s. And optical fiber can provide up to 100 Mbps above the rate.
Optical fiber door and limitations
Think about the BaiZhao optical fiber access the digital life, after an average download speed of 12.5 M per second, maybe just a smoke of time, a few G hd movie went down; The cloth wireless router, there can also be everywhere online, room, sitting room, sofa any scene, notebook, use PAD PSP any terminal, won’t because bandwidth after bypass Internet speeds drastically.
Now want to apply for BaiZhao broadband? According to information, BaiZhao business now have not opening, but unicom 10010 said, many Beijing plots have can apply for 8 million optical fiber door, the premise is users in a village have completed the optical fiber entering a transformation. According to Beijing unicom, old old village introduction optical fiber entering a transformation cost is higher, needs to be in this cloth fiber optic cable, and nearly three years to build the village, broadband coverage to enter a way optical fiber is given priority to, as early as in construction period has been buried cable in the building.
The present Beijing optical fiber door covered 3.4 million residents, unicom has launched a 8 M broadband service. According to unicom company introduction, the user if already dealt with other package, can apply for to change the way the difference for 8 M meal. Reporters from unicom to realize, if the user is original 1 M or 2 M of ADSL access way, with 8 M after the broadband, operators will free replacement a fiber interface electronic cat, the future even if bandwidth to upgrade, also need not change again cat, operators can upgrade to the cat remote control.
Than a large gap with international
The launch of optical fiber door to “home” life brings about change is obvious, but to worry about whether the price can bear. Of the 1680 yuan than 2 M years, has to be price launched unicom “walter family” 8 M package only need 1880 yuan, annual year 12 months not limit, fixed-line free rent for 3600 minutes, gave local the talking time. If the user is in 1880 yuan of the 8 M broadband basis, can add 50 yuan free 3 G mobile phone with a year of 66 yuan meal.
Although the price with the previous broadband charges very very competitive, but compared with the developed countries of the broadband still harder than charges still.
In the global scope, Japan and South Korea broadband penetration rate is highest, the fastest speeds two countries. In Japan, ordinary users home basically achieved 100 M, 200 M of bandwidth, highest can to 1 G. By 2010, 90% of the Japan family has access ultra-high speed (transmission rate for 30 Mb/s) network. At present, the 100 M of optical fiber cable was only 4000 yen, RMB for 300 DuoYuan, the cost per Megabyte only three yuan.
South Korea is the second largest global network of developed countries. Before 2007, 100 M fiber to the home has been popular. With SK, for example, broad-band open fee is 30000 won ($181 yuan), if the application is 1 year (with 1 years), opened the package fee also will be fired. Broadband fee to 3 years of the most economical, set contract flat-rate expenses to 29700 won ($180 yuan).
And in China’s Hong Kong area, 10 M broadband average $80 a month ($66 yuan). To Hong Kong broadband provide 100 M service, for example, costs per month for hk $121 ($100.5 yuan). At present the market a Hong Kong cable broadband, Hong Kong broadband, hutchison, PCCW, a number of other companies to participate in competition, “the price war” to break out.
In addition, Singapore nets velocity of 100 M network covers 35% of Singapore’s homes and buildings, and will be realized in 2012 95% of the coverage. Singapore’s residents have can enjoy 65 Singapore dollars (eur 322) / month of 100 M of fixed broadband service.
