NTT Data Chugoku Company (President: Kazuhiro Nishimura; Headquarters: Hiroshima City, Hiroshima Prefecture), Furukawa Electric Co., Ltd. (President: Mitsuyoshi Shibata; Headquarters: Chiyoda-ku, Tokyo), and Nippon COMSYS Corporation, Chugoku Branch (Branch General Manager: Hiroshi Watanabe; Chugoku Branch location: Hiroshima City, Hiroshima Prefecture) have jointly launched demonstration tests in Kagamino Town, Okayama Prefecture for passive disaster prevention sensors with the aim of reducing the damage caused by natural disasters.

The demonstration tests are being implemented to build systems capable of carrying out real-time monitoring of conditions during periods of sudden torrential rain, which have become more frequent in recent years, by identifying dangerous locations as quickly as possible and giving rapid and detailed predictions of when dangerous situations will arise.

Background and Aims

In recent years, extensive damage has been caused by sudden and localized torrential rain. There are limits to how much can be done to address this problem using structural measures alone, and there is an urgent need to provide an integrated approach that includes non-structural measures. In order to prevent damage from sudden torrential rain, there is a need to collect real-time information on flooding and rain volumes across a broad area. A need has arisen to identify detailed information in each region using the independent measurements...

SuperPower adds thinner substrate options to superconducting wire offerings- SuperPower adds a 30 micron substrate geometry to further increase product flexibility and increase current density

April 1, 2014 – Hannover, Germany – SuperPower Inc., a subsidiary of Furakawa Electric Company of Japan, is once again participating in the SuperConducting City Exposition at the 2014 Hannover Messe, the world’s premiere trade fair on energy and industry technology topics and has announced a new product offering to highlight an innovative technology and manufacturing advancement made over the past year.

Yusei Shirasaka, president of SuperPower, said, “we are pleased to announce the addition of a 30 micron substrate thickness option to our standard offerings of 50 and 100 micron substrate second-generation (2G) high temperature superconducting (HTS) wires. This new geometry was developed at the request of a number of our customers who will benefit enormously from the additional current density they will gain from this even thinner wire. Our 50 and 100 micron substrates have already been half or less the thickness of our competitors’ wires, offering an enormous advantage for coil configurations. The 30 micron option will give an even greater benefit in current density that leads to smaller size and lower weight of devices.”

“Advanced Conductor Technologies has been eagerly awaiting this new, thinner profile conductor for incorporporation into our high current density Conductor on Round Core (CORC) cable,” said Dr. Danko van der Laan, founder and chief executive officer of the start-up company located in Boulder, Colorado. “The 33% reduction in conductor profile in combination with much better mechanical properties, will contribute to an increase of as high as 50 % to our extremely current dense, flexible cable that is being eagerly awaited for incorporation into devices...

Successful Miniaturization of Next-generation Optical Waveguide Chip- Realization of higher density integration -

16/06/2014

0

Furukawa Electric has succeeded in reducing the chip size in next-generation silica-based optical waveguide circuits(note 1) (hereinafter called, PLC) to less than one tenth of the size of conventional chips. This has made it possible to realize the high-density integration of the circuits.

Two presentations related to this technology will be given at OFC2014 to be held in March this year, the largest international conference in the optical communications sector in the world. These presentations will be on “Ultra-small coherent mixers” and “Low loss connection technologies for super high refractive index PLC (hereinafter called “super high Δ PLC”).”

Background

In recent years, the arrival of smartphones and the spread of moving picture distribution and social networks, etc., have resulted in an explosive increase in communications traffic. In order to realize this advanced information-oriented society, it is necessary to realize ultra-high speed and large-capacity transmission.

The introduction of the optical digital coherent system(note 2) is being accelerated as a step to achieve this ultra-high speed and large-capacity transmission and there is a requirement for the provision of optical components and terminal equipment to achieve this. There are also demands for more compact, higher functioning and lower costing optical devices and in order to satisfy these demands, it is becoming necessary to develop innovative technology that goes beyond the design limits for conventional PLC.

Ethernet se consolida no Chão de Fábrica

Uma tendência dominante na automação industrial moderna está na migração de estruturas proprietárias de comunicação para a arquitetura de redes Ethernet e de Internet Protocol (IP). Conhecida como Ethernet IP, esta nova infraestrutura já atinge o chão de fábrica de diversos  tipos de indústrias.  “ As diferentes soluções de infraestrutura de redes  variam de acordo com a necessidade de proteção do local da instalação, mas a tendência é a utilização de redes ópticas, pois além de apresentar imunidade a ruídos eletromagnéticos possuem  maior largura de banda, além do custo decrescente ano a ano das interfaces ópticas”, diz Sérgio R. Scarpin, Gerente de Desenvolvimento de Produtos e Sistemas da Furukawa.

Segundo Scarpin,  dentro de uma mesma indústria existem variados tipos de ambientes: dos locais mais amenos, como as salas de equipamentos, até os ambientes críticos com presença de agentes químicos, umidade, poeira, entre outros agravantes que fazem com que haja uma variação do grau de proteção necessário para cada local.  “Os custos de instalação de uma rede industrial geralmente são mais elevados do que para uma solução comercial convencional, porém o objetivo é justamente fornecer proteção...

No Brasil, a convite da Furukawa para participar do Trade Show da marca, que reúne até sábado mais de 500 executivos de 15 países latinoamericanos na Praia do Forte, Bahia, o Dr. Durgesh S. Vaidya, gerente sênior de Pesquisa e chefe do Departamento de Soluções de Conectividade Óptica e Fibra Multimodo da Furukawa Estados Unidos falou na manhã de hoje sobre os desafios associados à gestão de infraestrutura de redes, cabeamento e conectividade nos atuais Data Centers.  “As crescentes demandas por aumento de capacidade em DC irão exigir taxas de transmissão de 400 Gbit/s a 6,4 Tb/s, requerendo o desenvolvimento de tecnologias inovadoras de fibras otimizadas para esta aplicação. Importante estar atento para os novos desenvolvimentos de fibras multimodo para operar em comprimento de onda 1060nm e para a tecnologia revolucionária de fibras com múltiplos núcleos de transmissão (multicore), onde apenas uma única fibra pode substituir o uso simultâneo de, por exemplo, 8 fibras ópticas da atual tecnologia disponível”, disse o especialista. 

Cenário - A crescente demanda por infraestrutura de redes para atender os mercados BigData, Cloud, SaaS, Vídeo Vigilância, Comunicações Unificadas (em Cloud UCaaS), Redes Sociais e Vídeo on Demand em toda a América Latina impulsiona os investimentos em Data Centers. No Brasil, os mercados...
