Successful Miniaturization of Next-generation Optical Waveguide Chip

11/03/2014

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...

Centro de Distribuição Multimídia (CDM) da Furukawa é tendência na construção e retrofit de casas e apartamentos

11/03/2014

0

Com o estilo de vida moderno exigindo uma série de recursos e integração de novas tecnologias nas residências de médio e alto padrão, requer dos fabricantes de sistemas de automação, eletricidade e telecomunicações o desenvolvimento de novas soluções que facilitam a instalação e resultam em mais conforto e segurança aos usuários. É o caso da Furukawa, líder global do segmento de infraestrutura de redes de comunicação, que desenvolveu uma solução de quadro de distribuição, semelhante aos quadros de energia elétrica, só que voltados para a integração e o gerenciamento dos novos serviços multimídia.  O Quadro de Distribuição Telecom Furukawa (foto) já está instalado em mais de três mil ambientes residenciais no Brasil e América Latina e é a nova uma tendência das construções modernas e retrofits. 

“O Quadro de Distribuição Telecom Furukawa irá disponibilizar e integrar os serviços de internet, telefonia, CATV, CFTV, som ambiente, home theater, segurança eletrônica e interfonia através de módulos e de um cabeamento estruturado, nos ambientes residenciais e em pequenos escritórios.”, diz Mariana Pauli Balan, da área de Engenharia de Networking da Furukawa.

Successful Development of a High-Temperature Superconducting Magnet for Next-Generation Flywheels

10/03/2014

0

The Railway Technical Research Institute (hereinafter called “RTRI”) and Furukawa Electric Co., Ltd. (hereinafter called “Furukawa Electric”) have been the first in the world to succeed at the development of a high-temperature superconducting magnet for large flywheels, using the second generation high-temperature superconducting wires manufactured by SuperPower Inc., a subsidiary of Furukawa Electric.(note 1)

This development is being carried out in cooperation with Kubotek Corporation, Mirapro Co., Ltd. and the Public Enterprise Bureau of Yamanashi Prefecture, as part of the project for the “Development of Technology for Safe, Low-cost, Large-size Battery Systems” being promoted by the New Energy and Industrial Technology Development Organization.

 

Summary of development results

 

  • We succeeded in the development of a high-strength high-temperature superconducting magnet by using second generation high-temperature superconducting wires(note 2) that use yttrium.
  • It was demonstrated that a load exceeding 2 tons can be supported without contact when this magnet is cooled to 50K (minus 223°C) and a high magnetic field is generated.
  • This makes it possible to operate at 50K (minus 223°C), which is a temperature considerably higher than with the conventional high-temperature superconducting coils that are cooled to 20K (minus 253°C). We therefore have the prospect of being able to reduce cooling costs.

KANZACC Composite Plating Suitable for Lead Frames for Semiconductor Equipment and/or Electronic Components is Developed

07/03/2014

0

KANZACC Co., Ltd. (Head office: Osaka City, President: Hisakazu Ishibashi) of the Furukawa Electric Group (hereinafter referred to as "our company") has developed composite plating with good heat resistance and good crack resistance as well. It is suitable for plating lead frames for semiconductor equipment and/or electronic components.

Semiconductor equipment and/or electronic components are created by covering each component on the lead frame with epoxy resin, etc. Especially, for the surface implementation type, the tip of the lead frame is bent in an L shape to make it easy to solder it to the circuit board. Also, the lead frame material is iron and/or copper alloy, and it is not possible to solder it as it is. Therefore, we plate it with tin and/or tin alloy (hereinafter referred to as "tin (alloy) plating"). In this case, it is a common practice to plate it with tin (alloy) after plating the substrate on the lead frame.

Furukawa, OFS and Corning Achieve Milestone for Optical Interconnect

06/03/2014

0

OFC/NFOEC 2014, Booth 4153, San Francisco, California, March 5, 2014 – Furukawa Electric Co., Ltd. has developed a vertical cavity surface emitting laser (VCSEL) that operates at 25Gbps and realized transmission of up to 500 meters over prototype multimode fibers developed by OFS and Corning Incorporated (NYSE:GLW). 

“This is a significant accomplishment for data communications as both longer reaches and higher speeds are required for warehouse-scale data centers.  Our customers are raising expectations as they implement next-generation data centers and we are pleased to be innovating the technology to meet and exceed those expectations,” said Dr. Haruki Ogoshi, senior fellow of Furukawa.

The rapid growth of cloud computing and expansion of “big data” is causing a dramatic increase in the volume of data handled in data centers. This has generated demand for greater throughput in servers, switches and routers in data centers.  Increasing the serial speed of transmission of lasers and photo detectors is one approach to that end. In addition, there is a need to increase transmission distances between devices as data centers become larger. In mega data centers, for example, transmission distances of 300m or longer can be required. At present, VCSELs at a wavelength of 850nm are widely used for lowest cost optical interconnect.  However, it is known that when the transmission speed is changed from 10Gbps to higher-speed 25Gbps, the transmission distance is limited to less than   200m due to the influence of chromatic dispersion in multimode fibers.
