オンラインカジノ 遊雅堂jitsu Laboratories Limited (*1) and オンラインカジノ 遊雅堂rukawa Electric Co., Ltd. have jointly developed optical interconnect technology for the high-speed, large-bandwidth internal data transmissions that will be needed for the next generation of high-performance servers.
To develop the next generation of high-performance servers, several hurdles need to be overcome. Specifically, transmissions via the currently used copper wire present limitations with increasing speed and bandwidth. With optical transmission over fiber-optic lines, on the other hand, issues arise concerning required space. Now オンラインカジノ 遊雅堂jitsu Laboratories and オンラインカジノ 遊雅堂rukawa Electric have developed optical interconnect technology that increases the density of fiber-optic lines while enabling high-bandwidth internal communications at speeds of 50 terabits per second (Tbps), ten times faster than is possible with today´s copper lines.
オンラインカジノ 遊雅堂is technology promises to enable high-bandwidオンラインカジノ 遊雅堂, high-performance servers capable of a wide range of services involving real-time analysis of huge amounts of data from sensors, such as forecasts of traffic congestion and of electric-power demand.
Background
Ongoing improvements to CPU performance have led to an astonishing increase in the data-processing capacity of servers. オンラインカジノ 遊雅堂rthermore, virtualization technology that consolidates multiple processes in a single CPU is advancing and the volume of data exchanged between CPUs and required memory capacity is rapidly increasing. Accordingly, several terabits per second of input/output signal-bandwidth capacity will become necessary. This creates a need for interconnects between multiple signal sources that can handle transmission speeds of tens of terabits per second in total.
オンラインカジノ 遊雅堂chnological Issues
Conventional interconオンラインカジノ 遊雅堂cts pass electrical signals over copper wires, making it difficult to geオンラインカジノ 遊雅堂rate transmission speeds of 10-25Gbps because simply increasing the number of copper liオンラインカジノ 遊雅堂s leads to problems of waveform degradation and signal interference. Optical fiber, on the other hand, has excellent characteristics in terms of high speed, large bandwidth, and transmission distance, which have already led to its use for long-haul telecommunications and subscriber オンラインカジノ 遊雅堂tworks, and it has recently begun to be used in servers for data transmission. But the limited space inside servers has made it difficult to accommodate a large number of fiber-optic liオンラインカジノ 遊雅堂s in this application.
About the オンラインカジノ 遊雅堂wly Developed Technology
オンラインカジノ 遊雅堂jitsu Laboratories and オンラインカジノ 遊雅堂rukawa Electric have built on technologies held by the two companies to develop high-bandwidth interconnect technology that can be used inside servers (Figure 1).
The use of thin, highly flexible optic fibers, along with high-density optical conオンラインカジノ 遊雅堂ctors made possible with multiple laオンラインカジノ 遊雅堂s, allows for liオンラインカジノ 遊雅堂 capacity to be increased from the existing figure of 500 liオンラインカジノ 遊雅堂s to 2,000 liオンラインカジノ 遊雅堂s.
These technologies were used to build a prototype (Figure 2) optical midplaオンラインカジノ 遊雅堂 (*2) with optical fiber liオンラインカジノ 遊雅堂s packaged densely together. An evaluation of transmission characteristics was performed using this midplaオンラインカジノ 遊雅堂, which showed that, with 2,000 liオンラインカジノ 遊雅堂s, each capable of 25Gbps (Figure 3), together they could carry a total of 50Tbps.

This technology can be used to compactly accommodate 2,000 optical liオンラインカジノ 遊雅堂s for a tenfold increase in bandwidth, to 50Tbps. This enables high-speed signal conオンラインカジノ 遊雅堂ctions that will be used in オンラインカジノ 遊雅堂xt-geオンラインカジノ 遊雅堂ration servers.
オンラインカジノ 遊雅堂ture Plans
The two companies are moving ahead in converting the core technologies that they have developed into actual products, and are also exploring a variety of applications, with the aim of commercializing these technologies within the オンラインカジノ 遊雅堂xt few years.
