Description
Technical field
The present invention relates to technical field of photo communication, specifically, it is the hybrid optical fiber current mutual inductor feed circuit being applied to optical communication field.
Background technology
Optical communication (OpticalCommunication) take light wave as the signalling methods of carrier wave. The method increasing light path bandwidth has two kinds: one to be the single channel transfer rate improving optical fiber; Two is the number of wavelengths increasing transmission in single fiber, i.e. wavelength-division multiplex technique (WDM).
Metropolitan Area Network (MAN) (MetropolitanAreaNetwork) is the compunication net set up in a city scope, is called for short MAN. Belong to broadband local area network. The local area network technology having active switching components owing to adopting, transmits time delay less in net, its transmission medium mainly adopts optical cable, and transfer rate is more than 100 mbit.
An important use of MAN is used as backbone network, will be positioned at main frame, the database of different location, same city by it, and LAN etc. links up mutually, and the effect of this and WAN has similarity, but both have very big difference in implementation method and performance.
Based on a kind of large-scale LAN, usually use the technology similar to LAN. The major cause that what MAN was independent list has had a standard: the two bus DQDB(DistributedQueueDualBus of distributed queue), i.e. IEEE802.6. DQDB is made up of two bus, above all computers are all attached at.
Broadband metropolitan area network (BMAN) is the focus of China's informatization, DWDM(dense wave division multipurpose) enormous bandwidth and the transparency of transmission data, the beyond doubt one preferred technique in current fiber optic applications field. But, MAN etc. have that transmission range is short, topology flexibly and the feature such as access style is many, as indiscriminately imitated the DWDM being mainly used in long-distance transmission, inevitable cost is too high; The property versatile and flexible such as MAN also are difficult to adapt to by early stage DWDM simultaneously. In the face of the broadband demand of territory, this kind of low cost city scope, CWDM(Coarse Wavelength Division Multiplexing) technology arises at the historic moment, and becomes the equipment of a kind of practicality very soon.
Concerning optical communication, its technology is substantially ripe, and business demand relative deficiency. To be described as the FTTH of " broadband access ultimate aim ", its actualizing technology EPON fully matured, but the bandwidth needed of surfing the Net due to domestic consumer is not high, makes the commercialization of FTTH be only limited to some model regions. But, in 2006, along with the treble plays such as IPTV are carried out, the bandwidth that operator provides can not meet user to the requirement of high definition television, and schedule has also been put in the deployment of FTTH thereupon. It is not unique, but has its counterpart, and ASON to transmission network control flexibly, can be corporate client and provides personalized service, and many operators are for development and maintain corporate client, spare no high price investment construction ASON.
The ultimate aim of future transmission network, is build all-optical network, namely realizes completely " Optical Fiber Transmission replacement copper transmission " at connecting network, Metropolitan Area Network (MAN), backbone network. Backbone network and Metropolitan Area Network (MAN) have achieved entirely photochemical substantially, and part network develops region faster, also achieve the light entering and copper back of the Access Layer of part.
Laser apparatus, nineteen sixty July 8, the graceful invention of American scientist plum first laser apparatus ruby laser in the world, from then on people just availability matter and electromagnetic wave phase like and the light source of frequency stabilization. From then on the epoch of research modernization optical communication also start. The English abbreviation of laser apparatus, LASER, is meant to " light amplification of stimulated emission ". Light and the common light of this kind of laser apparatus generation are different, and it is the light determined by material atom structural nature, and frequency stabilization, is about 100 terahertzs. The frequency of the microwave (frequency is about 10 megahertzes) of the frequency ratio of this kind of light widespread use is high 10,000 times. Therefore, transmitting information in theory with this kind of light, the capacity of communication could than the capacity of micro-wave communication also big 10,000 times! Therefore, the research work of optical communication is created great impact by the invention of laser apparatus. But the laser apparatus of initial invention at room temperature can not non-stop run, therefore, also can not obtain practical application in the communications.
Optical fiber, the mankind never abandoned the searching to desired light transmission medium, through unremitting effort, it has been found that the silica glass silk that transparency is very high can pass light. This kind of glass yarn is called optical fiber, is called for short " optical fiber ". People have manufactured at endoscope medically with it, such as, make gastroscope, it is possible to observe situation in the body of distance about a meter. But its attenuation loss is very big, can only transmit very short distance. The extent of deterioration of light is that unit is weighed with the decibel of every km. Until the sixties in 20th century, the attenuation loss of best glass fibre is still at every kilometer more than 1000 decibels. Does is what concept the loss of 1000 decibels every kilometer? every kilometer of 10 decibels of losses are exactly only leave 1/10th after the signal inputted transmits 1 kilometer, 20 decibels are only left mono-percent with regard to representing, 30 decibels refer to only surplus thousandth ... the connotation of 1000 decibels is exactly only be left 100000100 mono-, in any case also can not be used for communicating. Therefore, there were a lot of scientist and inventor to think to communicate with glass fibre and have slim hopes at that time, and lost confidence, abandon the research of opticfiber communication.
The invention of laser apparatus and optical fiber, makes people see the dawn of optical communication. And to be realized opticfiber communication, in addition it is also necessary in the performance of laser apparatus and optical fiber, there is great breakthrough. But the breakthrough in these two aspects encounters many difficulties, especially the loss of optical fiber to be reached the requirement that can be used for communication, is reduced to 20 decibels from every km loss 1000 decibels and seems unlikely, thus a lot of scientist to realizing, opticfiber communication loses confidence. Just in this case, it is born in English mat Chinese Gao Kun (K.C.Kao) doctor in Shanghai, by, on the basis of the big quantity research done in British Standard telecommunications laboratory, lightwave communication having been made a bold imagination. He thinks, since electricity can along metal wire transmission, light also should along the glass fibre transmission leading light. In July, 1966, high Kun has delivered the paper with great historic significance with regard to the prospect of Optical Fiber Transmission, the major cause that Article analysis glass fibre loss is big, courageously foretell, as long as the impurity of glass fibre can be managed to reduce, the loss of optical fiber is just likely made to be reduced to 20 decibels/kilometer from 1000 decibels every kilometer, it is possible to for communication. This section of paper makes the scientist of many countries be inspired, the confidence strengthening as realizing low loss fiber and make great efforts.
First low-loss silica fibre in the world---1970, three scientific research personnel's horse riel of U.S. CORNING glass company, perlon-1, Kai Ke successfully made the optical fiber that the every km of transmission loss only has 20 decibels. Does is what concept this? compare with the transparency of it and glass, light through glass power loss half (being equivalent to 3 decibels) length respectively: simple glass is several centimetres, senior opticglass at most also only several meters, and is that the length of the optical fiber of 20 decibels can reach 150 meters by every km loss. The transparency of optical fiber has exceeded hundred times than glass in other words! At that time, making the so low optical fiber of loss it may be said that be shocking action, this indicates that optical fiber is for the real possibility that communicated.
The road of optical fiber---if I can't do it, who can
The important breakthrough of laser apparatus in 1970 and these two gordian techniquies of low loss fiber, makes opticfiber communication start to become possibility from ideal, and this causes the attention of Enforcement of Telecommunication scientific and technical personnel immediately, and they competitively carry out studying and testing. Within 1974, low loss fiber manufacture method has been invented by Bel institute of the U.S.---and CVD (vapor deposition method), makes fibre loss be reduced to 1 decibel/kilometer; 1977, Bel institute and NTT almost succeeded in developing the semiconductor laser that the life-span reaches 1,000,000 hours (in practical about 10 years) simultaneously, thus have had the laser apparatus of real practicality. 1977, Article 1 opticfiber communication cable put it into commercial operation in Chicago,U.S city in the world, and speed is 45Mb/s.
After entering the practical stage, the application development of opticfiber communication is very rapid, and the opticfiber communication cable of application repeatedly updates. The opticfiber communication cable of the seventies, mainly with multimode optical fibers, applies short wavelength's (850 nanometers) wave band of optical fiber, (1 nanometer=1,000 1/1000000th meters). Using long wavelength's (1310 nanometers) after the eighties gradually instead, optical fiber adopts single-mode fiber gradually, and to the beginning of the nineties, message capacity expands 50 times, reaches 2.5Gb/s. After entering the nineties, transmission wavelength turns to 1550 longer nano wave lengths from 1310 nanometers again, and brings into use the new technology such as fiber amplifier, wavelength-division multiplex (WDM) technology. Message capacity and repeater span continue to be doubled and redoubled. It is widely used in local telephone system relaying and the long-distance main line that communicates, becomes the backbone of communication link.
Moore's Law, as far back as 1964, Intel company originator Gordon mole (GordonMoore) asserted in one section of very short paper: every 18 months, the performance of unicircuit will double, and its price will reduce half. This is exactly famous Moore's Law. Thus, the speed of microprocessor can be doubled for every 18 months. This just means that every 5 years its speed can be fast 10 times, every 10 years can be fast 100 times. The microprocessor of equal price can become faster and faster, can become more cheap and more cheap with the microprocessor of uniform velocity. Can infering, in future, people all over the world not only by the computer internet of oneself, but also can be surfed the Net by their TV, phone, e-book and stored value card. As the law that meaning in semi-conductor development history up to now is the most far-reaching, Moore's Law by the unicircuit developing history of nearly 40 years accurate verify.
Ji Erde law, George Ji Erde once predicted, at following 25 years, every 6 months were doubled by the bandwidth of backbone network. Its rate of growth exceedes 3 times of the CPU rate of growth of Moore's Law prediction. Today, nearly all well-known MCI is all in ground lay cables of always enjoying it. When bandwidth becomes enough abundant, the cost of online also can decline. In the U.S., a lot of ISP has been had today to provide the service of Free Internet Access to user.
Mai Tekaerfu law, the contriver Bob Mai Tekaerfu of Ethernet tells us: network value square is directly proportional with number of network users. If machine is unified into a network, on network, everyone can see other people contents all, and everyone content that can see 100 people of 100 people, so efficiency is 10000. 10000 human efficiencies are exactly 100000000.
United Nations's " forum meeting of 1999 WorldComs " vice-president John Luo Si (JohnRoth) proposes " new Moore's Law "---optical fiber law when forum's opening was delivered a speech on 10th, the every capacity that can double for 9 months of internet bandwidth, but cost reduces half, change going back for every 18 months of speed than wafer fast.
Moore's Law (Moore'sLaw) is used for describing the quick change of semi-conductor science and technology, and on average every 18 months, the capacity of wafer can grow up one times, and cost but reduces half; " optical fiber law " (OpticalLaw) is then used for describing the network technology.
