Intelligence, begin from change a cable
Is it is it enter one cable to lead to need only, surf the Net, phone, watch TV, water, electricity and gas 3 form collect copying, electrical home appliances intellectual control Everything can be realized.
In January of this year, the country determines to accelerate advancing telecommunication network, television network of radio and Internet " three networks are merged " . Build under overall arrangement for strong intellectual electric wire netting in the national electric wire netting company, network information communication limited company of the country advances the electric optic fibre to a pilot building-up work actively. At present, the optic fibre compounds the low-voltage cable is developed successfully, the pilot project is chosen and conceptual design move forward smoothly, pilot construction is like a raging fire.
On June 13, the national electric wire netting company holds the electric optic fibre to a pilot working forum in Shenyang of Liaoning, indicate electric optic fibre gets a pilot project is started in an all-round way, such province-governed municipalities as Beijing, Shanxi, Liaoning, Qinghai, Ningxia, Henan,etc. reach the electric optic fibre the rising space agenda of a pilot work one after another. According to schedule, 14 network save 20 cities of Company and launch pilot engineering construction, cover about 47,000 power consuming customer with altogether.
Terminate communication " The last kilometer " Question
2009, electric optic fibre reach households of key technology make great breakthrough, article 1 in the world used in optic fibre that commerce run compound low-voltage cable develop successfully. It is researched and developed independently by network Xintong Co. of the country, collect optical cable, electricity transmit electricity cable on an organic whole, support many kinds of transmission technology.
Because of transmit electricity electricity cable and optical cable function combine into a single unit, optic fibre compound low-voltage cable is it solve restrain This bottleneck of questions, are praised as " the last kilometer " The question " The terminator " .
The power line has already deepened the huge numbers of families as the most widely covered network resource. The communication optical cable enters the family and building with the cable, can solve such problems as the potential safety hazard is stressed mixed and disorderly of house phone cable of the building completely, and while laying the cable, finish the optical cable to lay, avoid the construction two times, thus lower costs greatly, economize resources.
As a new things that has just succeeded in developing, optic fibre compounds the stability, tolerance of the low-voltage cable also remain to examine. For this reason, network Xintong Co. of the country puts up" the electric optic fibre of intellectual electric wire netting of the national electric wire netting company reaches the family " ( PFTTH) System testing " Platform, build up an electric optic fibre to a technological laboratory, does not have mere network of source to launch the complex cable group network way of optic fibre, based on Ethernet way ( EPON) Only transmit equipment performance sum " Three networks are merged " Such mock tests of the laboratory as business application,etc..
Through test, adopt optic fibre compound low-voltage cable and based on Ethernet way to have smooth network of source ( EPON) The electric optic fibre of technology reaches a system, has already realized that gather the function and bear the weight of " three networks are merged " in information of long-range power consuming based on optic fibre The function, demonstrate good stability.
3 plus 1 is greater than 4
The electric optic fibre reaches a technology to make the access technology of the modern communication network enter the family, serve the country " Three networks are merged " Strategy is while building strong intellectual electric wire netting, merge telecommunication network, television network of radio, Internet, enable ordinary family to enjoy the large capacity, high bandwidth, high-quality communication service, have used and offered the good environment with the electricity and informationization for family's intelligence.
Telephone wire, cable TV line, Internet line add the electric wire, does 3 plus 1 equal 4? In fact, the electric optic fibre can meet one's own development of strong intellectual electric wire netting's needs to reach a technology, can serve in an all-round way " Three networks are merged " Strategy, produced" 3 plus 1 is greater than 4 " Benefit.
The first batch of electric optic fibres of our country built up in Beijing, Shanghai, Wuxi, Jiangsu reach the demonstration project of a intellectual district, users can insert Internet through the electric optic fibre directly, dial the digital telephone, watch the high clear TV, and control such intellectual electrical home appliances as air conditioner, electric heater, electric cooker,etc., realize electricity, water, three angry form integrated application.
It only takes a line, can support the intellectual power consuming system. Not at the home as you, can by telephone household appliances, remote control of you, it can " clever " Serve you. Did you imagine how to move the electric apparatus? What do we rely on to come to control it? Answer whether one optic fibre compound low-voltage cable, it support whole intelligence serve technological means of system with electricity. Through an electric wire, all functions that community service, power consuming information are gathered,etc. that we can realize the video converse. The intellectual electric apparatus putting the intellectual socket will be linked with mutual terminal station of intelligence through the electric wire to only need when we want to control the intellectual electric apparatus, the mutual terminal order issued signal of intelligence can be transmitted to the electric apparatus through the electric wire, the electric apparatus is known " Obediently " Finish the work that we want it to do.
It only takes a line, can structure the power network and communication network. At present, strong intellectual electric wire netting construction move forward smoothly, the equipment, distributed clean energy of a large amount of intellectual power consuming need to insert the electric wire netting, the real-time information exchange between users and electric wire netting presents the exploding type to increase. The implicit many core optic fibre of electric optic fibre, can also be used for structuring the public network platform that is totally opened except that enterprise use the power supply network, offer service of inserting for telecommunication, Internet, broadcast and television and other fields. Use the electric optic fibre in a unified manner, accord with the country and advance the network infrastructure to build together the thinking shared, can widen the construction operation mode of the optic fibre network too.
Use a line, can economize the cost greatly, reduce " three networks are merged " by a wide margin Investment. At present, the electric wire netting of our country has already covered most families, the popularity of and Internet is only 30%, the popularity of the cable TV is only 40%, the coverage rate of the electric wire netting is far greater than Internet, telecommunication network and cable television network. Implement " three networks are merged " Must insert a large number of optic fibre broadband, consider such factors as equipment, consumptive material,etc. synthetically, lay the electric optic fibre in the newly-built residential building, lay the optical cable and reducing greatly of the power line cost than respectively, have not been putting through the old town of broadband and rural remote area yet at the same time, has implemented the electric optic fibre and registered one's residence, can advance the process of surfing the Net with broadband greatly.
In addition, use a line, can improve and run efficiency synthetically. About advancing the construction plan of the broadband network according to such seven ministries and commissions as industry and information-based department,etc., by 2011, urban user's optic fibre broadband access ability wants to reach 8 megabits per second equally. If adopt the electric optic fibre to the family, the network has very large promotion space to insert ability in the future. Meanwhile, in the electric optic fibre, the transmission of the optic fibre signal in the optical cable does not interfere each other, and optic fibre and optic fibre of transmission network information which transmit the information of the electric wire netting totally realize physics is isolated, can separate and come from Internet and attack of production control of electric wire netting effectively, will not produce the potential safety hazard, the electric optic fibre reaches the comprehensive operation efficiency that high bandwidth and high security that the family has will raise the network in an all-round way. |
