Support the cloud social era of fiber optic cable to cope with the demand of high speed large capacity ~

In the optical fiber support cloud social network is based.Optical fiber is made of quartz glass and plastic thin fibers, from the central part of the fiber core and cladding in the double structure of the surrounding cladding, it is through the principle of total reflection, the optical signal to signal enclosed inside the fiber core, transmission medium for data transmission.Because is not affected by electromagnetic wave, therefore communication stability is high, has the nature of the large capacity and long distance transmission can be realized.Sumitomo electric集团从1974年开始制造“光缆”以来，历经40多年，一直开发和提供各类产品。

Now, sumitomo electric group of optical communication career field, which can be roughly divided into "general optical fiber", "submarine optical fiber business" and "cable"."General optical fiber business" and "undersea optical fiber business", the object product, is the optical fiber core, as one of the optical signal transmission way and the cable is not the object product, it is extremely thin fiber core layer stranded after outsourcing processing processing, such as fiber optic cable can be used in indoor and outdoor environment.As a result, their respective market is different.General optical fiber has the nature of the homogeneity and without borders, and the cable is made according to customer requirements of various areas of localized products.Even within the sumitomo electric group, fiber optic product is positioned to internationalization, and cable have been positioning for products for the domestic market (land use)."Another" undersea fiber optic career, can be said to be the sumitomo electric group original technical area of development, has the world's No. 1 market share.

In Japan, starting in the 1980 s the cable laying, cable now covers nearly all Japan.Therefore, the next key battleground of general optical fiber will be transferred to abroad.On a world scale, optical fiber has a tendency to expand the market, especially the development of China's market is remarkable.Even within the sumitomo electric group, compared with a decade ago, Japan's domestic and foreign sales ratio has been reversed, now about 75% of its sales are geared to the needs of foreign markets.China also has a great help to the promotion of earnings.Now, sumitomo electric group of the market share of the fiber, among the world's top group also has a place, but to expand market share is not the only goal.At the end of the optical communication enterprise minister mutuality said: how to deal with social and the needs of customers is the most important thing.

"In the future, factors demand to the optical communication system, will focus on high speed large capacity, low latency, *, and high reliability of the 3 points.I think, to achieve high standards of these elements, is our mission.For example, in order to realize high speed large capacity this element, one of the key is to reduce transmission loss to limit.Doing this can improve the receiving sensitivity, more optical signal transmission.In addition, if you can receive a lot of fiber in a fiber optic cable, you can achieve high efficiency, high speed large capacity.Though the achieve the elements of the product is super multicore cable, but "more than the core" and "extremely low loss 'realization is very important for high speed large capacity, is the realization of the main points of the differentiation and other competitive company, also the company is now the most emphasis on move forward".

* delay: from the transmission way of end-to-end needed signal transmission time.

Sen expression is the background of the words at the end of the market of dramatic change.In the past, cable operators mainly for network users.But as the changes of The Times, fiber optic cable users in the event of a paradigm shift.This is due to the beginning of the article mentioned the development of "cloud computing", is to provide the cloud service suppliers have the existence of the data center.These service providers, is based on the positions, with the most sophisticated IT as a weapon, a global presence of a large IT company, now they are constantly to the operation of the cable and its own users.Not only is to make the huge information flows, provides the software, storage and servers and other IT resources, the information as the big data, will also become the important resources in the enterprise strategy.They have most of the data center, have tens to hundreds of thousands of servers, really is a very large scale.In addition, the shoulder to connect local multiple data center floor, is the high speed large capacity optical cable, namely sen mentioned at the end of the "super multicore cable".In the next chapter, we introduce sumitomo electric group to realize fiber concrete measures of the multicore.
