Telecom Beijing war broadband speed

More than a month ago, the National Development and Reform Commission announced plans to investigate and deal with China Telecom and China Unicom broadband monopoly to a post on broadband monopoly caused by the voices of criticism of high broadband prices, however, now, this situation will change. It is reported that Beijing Telecom has developed a "small and medium-bandwidth scale to expand the marketing implementation plan, according to the plan, the Beijing Telecom will start large-scale force broadband market.
Experience users have of life in Beijing, compared to the south of Jiangsu, Shanghai, Guangdong and other provinces and cities, Beijing's broadband rate has been significantly behind. In October 2011, Shanghai Telecom announced its full speed of over 4 million homes and businesses broadband users, individual users maximum free rose to 30M; subsequent Jiangsu Telecom announced the opening up home broadband rates up to 100M and substantive launched packages; Guangdong Telecom also announced last month, users can upgrade to 100M.
Insiders said this is mainly because China Telecom and China Unicom's fiber optic construction time, China Telecom in the south start earlier, China Unicom fishes fixed-line fiber-optic equipment Jicai completed in November 2011. China Unicom recently concluded 2012 meeting also proposed that China Unicom will be popular in cities across the region more than 4M access bandwidth, conditional popularity of 10M to 20M access bandwidth.
Beijing Telecom, the plan shows that the implementation of broadband speed will be the first in Beijing, the estimated average rate of home broadband entire network will reach 4.7M, 2.5 times faster, the highest speed up to 20M, which is obviously a temptation to the user.

Fiber Optic Attenuator

Fiber optic attenuators are devices that reduce signal power in fiber optic network by inducing a fixed or variable loss. Fiber optic attenuators are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors. Fiber optic attenuators use several methods of attenuation. Examples include air gaps, micro-bends, acoustic-optic modulators, and electro-optic modulators.

Before, the largest Kenyatelecom operator Safari company forecasted that Kenya's Internet application will increaserapidly after one year. The company plans to laying the backbone fiber-opticcable, in response to the resulting "data tsunami”. The company’s 40% ofthe shares held by Vodafone UK which is the largest telecom operators in Kenya.It offers internet data service to more than 5 million users and the number ofmobile phone users reached 17 million, which is far ahead of other competitors.However, due to the lack of all fiber-opticcable network, Safari has been to rely on other companies' cables to transferdata. Because of the increasing amount of data, the browsing speed instability,broken net frequently, highlight the lag of the telecommunications in frastructure.

It isreported by Kenya Journalof Commerce, Safari company CEO Bob kerry claimed ,because of the rapid development of internet market , the rapid growth ofmobile phones and other mobile devices, as well as a variety of Internetapplications,users have becomeincreasingly demanding high bandwidth and speed of data transmission on theInternet, it will usher data tsunami in the next 12-18 months,that is, data traffic is like a tsunami-like explosive growth.To this end, the company will invest in the laying of newfiber-optic cable to meet customer needs.

We are committed to providing customers around the world to provide comprehensive products, the latest technology and professional services to help customers to build high-quality network platform, combined with the actual needs of customers, and providing individualized to meet customer demand for a comprehensive solution .

With the advancement of technology, there were many inventions and discoveries. The newest one has long been that of soluble fiber optic cables, which have gained far more prominence in the sector compared to copper cables. These cables are broadly employed in workplaces or residential areas. study the create up forward to understand the differences between Fiber Cable and copper cable:

About Copper cable television and Fiber Cable Copper cables transmit info via electric signals. It has long been employed like a speaker technique wire, phone wire, pc cable television cable etc for more than many years now. Fiber Cable comprises of plastic material or cyrstal glass strands to transmit info or info digitally using the utilization of gentle instead of electricity. around the other hand, copper cable television encompasses of the one thread of copper. The size within the cable television varies is dependent upon its purpose. Sometimes, the cables are protected using the help of the covering recognized as braiding. The distinction between copper cable television and soluble fiber optic lies here since the latter cannot transmit electricity but recognized for delivering substantial theoretical performance.

Difference between Copper cable television and Fiber Cable The significant distinction between copper cable television and Fiber Cable is their numerous resistance versus interface. Copper cable television is fairly weak versus signal interface that arrives from microwave or cell phones. With utilization of soluble fiber optic cable, you are free from all these problems. Moreover, copper cables are affordable and suitable for all your house requirements. soluble fiber optic cables can transmit info to prolonged distances and far more swiftly compared to copper cables. Moreover, this cable television has less excess fat and also a smaller diameter producing it significantly much better than its counterpart.

Furthermore, these soluble fiber optic cables require less power and so are inflammable. Copper cables can be electromagnetically tapped whereas Fiber Cables are not easy for being tapped not having interruption in the signal. Fiber Cable help in multi-channel transmission although the use of the one line. Therefore, this cable television finds broad app in wiring of home theatre models and is also as well pricey than copper cabling.

But the added advantage of utilizing the soluble fiber optical cables are which they provide increased bandwidth and so are easy for being set up than copper cables. soluble fiber optical cables possess the capability to hold signs that include millions of megabits or terabits every next as in comparison to copper cables, which could hold 2.5 megabit every second. Also, soluble fiber optic cables provides protection and less attenuation percentage but calls for minimal maintenance. LANs (Local place network) also use soluble fiber optics in the backbone and copper cables for your desktop.

The basic theory of optical signals in optical fiber transmission

It’s a new technology that using lightwavetransmission of Television signals and data in the late 20thcentury. And its emergence makes the world’s IT industry have a rapid development,now Optica transmission technology is developing fast which is beyond people’simagine pace, its speed improved for 100 times compared with it 10 years ago,another 100 times will be gained in the future. With the continuous developmentof fiber optic transmission technology, in optical domain, it can be applied inmultiplexing, demultiplexing, routing, stwiching, the network can takeadvantage of the huge fiber bandwidth resourses, increase network capacity andto achieve “ transparent” transmission of a variety of business..

Optical transmission system is made up of Opticaltransmission, Optical receiver, Optic fiber cables and other components.

The Optical transmission technology is in the shape of the opticalsignal transmission between sender and recipient.The work for optical transmission television signal is toprocess among optical transmitter, optic fiber cables and optical receiver: Theoptical transmitter in the center room to transform the input RF televisionsignals into optical signals, by the electrical / optical converter(Electric-Optical Transducer, E / O) to complete, and transformation into theoptical signal received by the optical fiber transmission orientation device(opticalreceiver) to receive the optical receiver to transform the opticalsignal obtained from the fiber to restore into electrical signals.Therefore, the rationale of the optical transmission signal is the wholeprocess of electricity / light and optical / electrical conversion, also knownas the optical link.Now light transmission is using light intensity modulation.Such as the so-called coherent light of laser light device issued by aphase-coherent, so take the luminous intensity of the overall changemodulation, which uses the output optical power corresponding to the electrical/ optical converter input signal current changes linearly with changesinfeatures. 

In the optical / electrical converter (Optical-Electric Transducer, the O/ E), the output is proportional to the input optical signal intensity of thecurrent, the output current waveform of the optical / electrical converter andtherefore the electrical / optical converter input current waveform similar,reaching the purpose of signal transmission. So, how do optic fiber cablesorient the optical signal? The fiber optic cable system is a cylindrical fiber,by fiber cylinder and a cladding composed of quartz glass material. Claddingplays a role in the light tightly enclosed in the fiber to protect the core,and enhance the strength of the fiber itself, while the function of fiber is totransfer optical signal.Although the core and the cladding ofquartz glass materials from production, but in the production of both dopedcomposition, resulting in a refractive index of different sizes (1.463 ~ 1.467core cladding1.45 to 1.46) and, of course, related to the different materialsused. When the laser emission of the light source into the core, the incidentlight to the cladding interface, as long as the angle of incidence greater thanthe critical angle, will produce total internal reflection within the core, theleakage light does not reach all parts of the cladding, so that togetherintothe optical signal within the core will be uninterrupted spread untiloriented optical receiver. The procedure is the theory that optical signal tranfers in optical fiber cable.
