The famous scientist Maxwell further expressed with mathematical formulas research results Faraday and others, and the electromagnetic induction theory to the space. In his view, the change of the magnetic field around the field will produce changes, changes in the electric field around the turn produce changes in the magnetic field, such as layers of the same wave pushed to go, you can put an alternating electromagnetic field very far. '64 Years, Maxwell made a field theory, become the first person in human history predicted the existence of electromagnetic waves. So, who confirmed the existence of electromagnetic waves have it? This person is Henrich 'Rudolph' Hertz. 1887 day in a dark room Hertz experiment. He added two high voltage closely spaced metal pellets, resulting waves will produce crackling spark discharge. Then, behind him stood a no seal ring. When Hertz to ring the opening tune to a certain extent small phone pcb board recycling company, you can see sparks across a gap. Through this experiment, he came to the electromagnetic energy may spread beyond the space conclusions. Hertz announced after the discovery, a sensation worldwide scientific community. Of course, 1887 has become a milestone in the history of modern science and technology, in order to commemorate this outstanding scientist, an electromagnetic wave frequencies in the unit named 'Hertz (幵 magic' Hertz's discovery of epoch-making significance of professional mobile phone pcb board recycling, it Not only Maxwell's theory proved correct, more importantly, is to promote the birth of radio, opened a new era of electronic technology, it marks the transition from 'wired electric phone' to 'wireless phone' turning point, but also the entire mobile phone point of origin should be said that from this point onwards, humans began to enter a new field of wireless handsets. coaxial cable shield copper mesh can be expensive phone pcb board recycling, aluminum can also be a film-like, it's additionally One effect is to prevent foraging rodents destroy the bare wire insulating plastic layer and outer layer can be have a different shape, structure and strength of the mobile phone pcb board recycling, which generally depends on the installation conditions and operating environment and other factors when cables For example, used in outdoor environments due to the overhead cables will work in strong winds and rain, snow and other harsh environments, and therefore require high strength outer layer. transmission characteristics of the coaxial cable is superior to UTP, which is mainly due to the coaxial cables thicker copper conductors and better shielding layer thicker copper conductors can provide a wider spectrum, typically up to several megahertz. Further attenuation of the signal transmission is smaller, it can also provide longer transmission from the ordinary unshielded twisted pair is not grounded shield, so the error rate is much better than coaxial cable twisted pair, can reach the level of 10-9 coaxial cable of this structure, it has a high bandwidth and excellent noise rejection practical applications, depending on the available bandwidth of coaxial cable maximum cable length .1 dagger claws cable can achieve data transfer rates of 1? 2 (^ / 3, may also be used for longer cable, but the transmission rate would reduce or need to use a common coaxial cable signal amplifier, there are two: one is the 500-impedance coaxial cable for digital transmission, as used for baseband transmission, also called baseband coaxial cable. ; the other is the impedance of the coaxial cable 750 for analog transmission ^ also called broadband coaxial cable broadband coaxial cable, in use, its bandwidth may be divided into several ranges usually carries each frequency range. the respective encoded information, so that you can land on a single cable to transmit multiple data streams multiplexed Common specifications coaxial cable as shown in Table Jie .2 where phone pcb board recycling _ _ Henan Mobile Obo electronic pcb board recycling is supplied by Shenzhen Aobo Electronic Technology Co., Shenzhen City Aobo Electronic Technology Co. (www.aobodz.com) is Shenzhen, the other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness , and satisfy customer needs in Obo e-leadership with the staff warmly welcome all inquiries negotiations to create a better future for electronic Obo.
