The Koike Laboratory is researching next-generation broadband technology, based on the concept “Fiber to the Display.” This is not an extension of current Internet technology, which is based on electronics originating from Silicon Valley. Instead, the aim is to achieve “a broadband society that puts people back on center stage,” supported by super-high-quality displays and super-high bit rate. A key technology in this research is GI-POF (graded index plastic optical fiber), which was developed by Professor Koike. GI-POF is thick plastic optical fiber, with a core diameter of 1 mm. Because this fiber is flexible, it doesn’t easily break or penetrate other objects, and it can be processed freely. This new fiber makes it possible to install a fiber connection right up to the terminal of a communication network in the home, which was difficult with conventional quartz optical fiber. Q. “I think the Internet has greatly changed the way in which society utilizes information. But the more convenient the Internet becomes, the more communication is done through keyboards and the little screens of mobile phones. I think we haven’t escaped from the paradigm that people, even seniors, have to adapt to machines. I do think such forms of communication are great. But think what it would be like if your home had a window that was connected to the world. For example, if an elderly person feels unwell in the middle of the night, will he or she be able to communicate by typing on a keyboard

Fibre Optic Cable Strengthens The Communication Network

Fibre Optic Cable Strengthens The Communication Network

Article by Andre Kakkar









Today, Fibre Optic cable has become the prominent medium for high-speed transmission of large amount of data as well as for customized computer networking system. In spite of being expensive, most of the companies are installing optical cables to have un-interrupted and speedy transfer of information via wide range of computer devices.These days telecommunication applications of fiber-optic cable are widespread, ranging from global networks to desktop computers. Generally fibre cables are the bundle of thin glass threads (also called optical fibres) that are capable of transmitting any amount of data without any loss. These flexible fibres can be grouped together, and the resultant cabling network functions at superior bandwidths in comparison to other kinds of transmitting information media. Since these glass fibres go through low level of reduction and hindrance, they are extremely effective for various telephonic applications.

Nowadays internet is a most prominent mode of communication, thus use of fibre technology ensures secure data transmission and networking in seconds with minimal loss of records. Many different types of telecom providers, like cable businesses and telephone service frequently uses these advance cable to have fast and better mode of communication. In-spite of the cost factor, most of the traditional telephone lines is getting replaced by cable optic technology for smooth, safe and easy transfer of information.

Today, most conventional communications media including telephone, music, film, and television are reshaped or redefined by the internet, giving birth to VoIP service (Voice over Internet Protocol) and IPTV. With effective web network through modern fiber optic cabling structure, one can easily be able to watch live high-definition videos and movies, easily do video conference in real time, download large media files within moments and do a lot more things that are hard to do few decades before.

Wireless internet and fiber optics offer out of the ordinary services that not only needed by large business corporate but also can be made use of at home. But due to lack of knowledge many people tends to relate the CAT cable as optical cables. Generally these cables are comprised of four copper wires that are twisted together, very similar to phone line. As compare to fibre cable, later uses electrical signals to transmit data from one source to other. These copper wires are cheap to install but they are insecure and have risk of data loss while transmitting through different mediums. Fiber optical provide much better bandwidth transmission capabilities and security as compare to these Ethernet network cables.

Though expensive, optical technology is now being widely used as lan cable in most of the corporate offices and telecommunication industries. These are extremely useful for local-area networks or LANs which is confined to a relatively small area such as a single building or a group of buildings. With such large number of advantages, the time is not far when fibre optic cable will surely outshine all types of networking cable system.

Optical Communication: EPON and GPON extension skyrocketing competition slow down – Optical Communic

Article by jekky









2009, China’s optical communication industry can be said to be a year of harvest, by operators of broadband, 3G Construction-driven market year high heat. Most operators are finally beyond the scale of procurement in early 2009 expectations. With China Mobile For example, early plans to purchase 16 million core km of optical fiber, the final purchase amount up to 18 million core km. As the operator network construction has a certain continuity, high-speed optical communication market development trend will continue for at least 2-3 year. High growth for at least 2-3 years Optical communications market hot this year for the industry to gain much in the same time, the market also sparked concerns about the sustainability of high growth. Optical communications market trends this year to become a focus of attention. Telecommunications Research Institute of the Department of Planning transmission and access networks Hejian Wu, deputy director of research specifically on the “China Electronic Reported, “told reporters:” Judging from the current market trend, the rapid growth of optical communication market will continue for at least 2-3 years. Mainly due to the construction of operators is very large scale, not the year 2009, all construction completed on , operators in many construction projects, such as 3G network setup, broadband upgrades and so take years to complete. ” Fact, the exciting optical communication has only just begun. The feasibility and costs, FTTx ripe for large-scale commercial. FTTx industry concepts and experiments into the real size of the construction phase, as in the chain of universal benefit of the industry opportunities, optical communications boom will continue. In addition, 3G broadband mobile communications, consistent communications trends, promote its role in optical communications will continue for many years. China’s fast-growing optical communication market is rooted in the development of broadband services on the urgent need. Overall, our broadband is still at a low level stage. OECT (International Economics and Cooperation Organization) International organizations have long average network downlink speed reached 17M, while the current number of Chinese broadband users are still using the 512K. American Communication Association survey released in China, Internet speeds areas ranked 47th worldwide. Therefore, although China has become the world’s broadband subscribers than any other country, but still in the stage of low-speed broadband, and Japan and South Korea still lags behind other countries. China Unicom National Engineering Laboratory of business applications of broadband Deputy Chief Engineer Xiongyan said: “China is a big country of broadband, but not the power of broadband. From the business concerned, we have entered the era of broadband 2.0, which means a whole lot of video services Internet business the subject of a lot of user generated content itself, other P2P (person to person) business has become mainstream. this case for broadband access have a higher demand. ” EPON and GPON competition slow down From the current development of optical communications market perspective, this year will FTTx is the most important applications. Currently there are two main technologies FTTx EPON (Ethernet passive optical network) and GPON (G bit passive optical network), EPON occupied in the past is absolutely dominant. GPON in 2009 with the development of new breakthrough China Telecom , China Unicom are introduced GPON pilot. The light of the current development trend, EPON and GPON will be in China long-term coexistence, although there is still competition between the two sides, but has not “have you not me” relationship. “EPON in the past, China accounted for nearly 90% market share, occupy an absolutely dominant position. But recently operators for the use of GPON is being expanded, increased market share, this trend will continue until at least 2011.” CCID Consulting’s Communications Industry Research Center, Beijing, Deputy General Manager of holes on the “China Electronics News,” told reporters. Ericsson GPON Director MichaelGronovius product and market support also, “China Electronics News,” told reporters: “GPON industrial chain to be relatively more perfect than the EPON, the development of basic should be better.’s Future growth rate should be more than EPON. China’s current operators is increasing acceptance of GPON. “

How long fiber applications support – fiber optic, cabling, laser – HC Network Communication industr

Article by jekky









Commonly used in building fiber optic cabling system, there are three types: 62.5/125 m multimode fiber, 50/125 m multimode fiber, and single-mode fiber.

  With SYSTIMAXSCS development of a new 50/125 m, for low-cost 850nm laser-optimized fiber optic cabling systems for global applications, and standards have also joined the series.

Required to meet these basic types of fiber must meet minimum performance levels required, the broad bandwidth and attenuation that must meet the terms of the performance requirements. The application of standards for their transmitter and receiver define the minimum performance standards, and to meet the standards of the worst combination of circumstances to provide a solid specification.

Into account these issues, users, consultants and suppliers installers should ask the key characteristics of such fiber-optic security and support that. Support the validation of these may include several different “proof.” For multimode fiber, there is a “proof” to “overflowing bandwidth” or “high-limit mode of loading (RML) Bandwidth.” Another “proof” for “they have to test multiple products.” All these prove that are defective.

Multimode fiber is a multi-path transmission medium. It depends on the bandwidth of which path (or mode) signals. The initial path from the transmitter to enable the conditions to be. The bandwidth of the laser transmitter overflow (usually used for 155Mb / s or more applications) in bearing capacity of smaller minimum bandwidth performance, as the opening of these conditions far from the transmitter, and usually no overflow condition. RML bandwidth encountered the same problem. Experiments on the development RML conclusions apply only to 62.5 m fiber, only if and to meet the specific conditions of the transmitter is enabled only when used together effectively.

No one application is enabled by these conditions, studies have shown that the transmitter does not satisfy the conditions to enable widespread. Finally, the reliance on a small number of optical fiber test and come to the conclusion, that the manufacturer can not know how to select high quality performance.

, Of course, there are some manufacturers to extend the range of support and use of fiber optic 1300nm multimode transceiver link, such as 1000BASE-LX. Because there are not any standard provisions enabled 1300nm source conditions, the production of such transmitter may form a variety of methods of operation of various multi-mode fiber.

Therefore, these claims must indicate the spontaneous opening of all possible, or must rely on external conditions?? For example, by opening expensive mode conditioning patch cord compensation strict control mode is enabled. This 850nm laser optimized multimode fiber direct contrast, multi-mode fiber transmission characteristics with DMD control, consistent with the definition of spontaneous opening of 850nm application conditions.

But the multi-mode fiber in the 1300nm window, long-distance solution gives rise to another problem. Why do users need to install a new 1300nm multimode fiber to support enhanced 1000BASE-LX, and 1000BASE-LX transceiver was originally produced for the single-mode fiber.

People alternative solutions for multi-mode single-mode because it is multi-mode solutions, lower cost, rather than lower the price of fiber, in fact, multi-mode 850nm Electronic Instrument Much lower cost. This is why use optimized multimode fiber for transmission in the 850nm window, meaning. [Key words]: Optical fiber   Wiring   Laser Comment Large   In   Small
