Mitsubishi Electric's new optical transmitter
module lowers power consumption by 50%

Mitsubishi Electric Corporation's 10 Gbps optical transmission device cuts power consumption by 50% compared to conventional models used for high-speed large-volume data transmission between data centers. Comprising an electro-absorption modulator laser (EML) coupled with a transmitter optical sub-assembly (TOSA), the module transmits up to a distance of 40 kilometers thanks to its high-quality signal performance. Mitsubishi Electric will commercially launch its new EML-TOSA, known as the FU-613REA, on October 31.

The module complies with the 10 Gbps Miniature Device Multi Source Agreement (XMD-MSA) and uses in CAN packaging suitable for mass production.

The increasing use of high-speed, large-volume optical transmission devices at data centers accounts for the consumption of considerable amounts of electrical power, so Mitsubishi Electric's new power-saving EML-TOSA module is expected to attract considerable attention.

Significant drop in power consumption
(1) Power consumption of 0.6 W is approximately 50% less than that of Mitsubishi Electric's current FU-612REA model. 2) EML operability at high temperatures allowed the thermo-electric coolers to be downsized.

Long-range transmission
The module's newly developed EML chip achieves a low power penalty (difference in power before and after transmission), high extinction ratio (optical output ratio between "on" and "off" modes) and high mask margin (standardized specification indicating performance of optical output waveform), resulting in the capability to transmit data up to 40 kilometers.

Practical CAN-type package
Mitsubishi Electric adopted CAN-type packaging suitable for mass production, replacing box-type packaging used in conventional models.

Other features include
Light emission central wavelength: 1,530 nm to 1,565 nm; Output power: -2 to +2 dBm; Package size and electrical interface: XMD-MSA compliant; Operating temperature range: -5 to 85 degrees C; Power penalty after 40 km transmission: less than 1.0 dB (typ.); Extinction ratio: more than 10 dB (typ.); Mask margin: more than 20% (typ.);

Mitsubishi Electric begins full-scale testing of Smart Grid in Japan

Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has begun full-scale tests of smart grid and related smart-community technologies at the company's production sites in Japan. The aim of the project is to develop and test products including commercial systems,
equipment and solutions for annual sales worth 1.3 trillion yen (about 17 billion USD) by March 2016.

Through the project, Mitsubishi Electric intends to contribute to sustainable low-carbon societies establishing an economic and highly-reliable power grid. At the same time, the company aims to provide society with a system that enables consumers to visualize and control electricity consumption for optimized energy use. The project also focuses on the development of robust energy infrastructure that offers continuity in emergency situations, in the wake of the Great East Japan Earthquake.

Since May 2010, the company had been developing smart-grid infrastructure worth about 7 billion yen, including systems for supply and demand management, next-generation distribution management, advanced metering and energy management. The full-scale testing will focus on four main areas:

1) Demand-supply balancing: technologies and algorithm to manage a large amount of renewable energy connected to the power grid.

2) Distribution network management: technologies and equipment for voltage control, to prevent instability caused by a large number of photovoltaic systems installed in buildings and residences.

3) Total grid operation for the future: comprehensive evaluation of an envisioned environment in 2020, when a large volume of renewable energy will be connected to the network and electricity demand will be aggregated in communities.

4) Specific operation: technologies for independent micro grid such as island or partially connected regions.

The tests will also focus on the verification of smart grid technologies performances in very severe conditions for the power system including loss of part of the grid by earthquake, lightning and other weather related events.

Mitsubishi Electric Corporation (TOKYO: 6503)
With 90 years of experience in providing reliable, high-quality products to both corporate clients and general consumers all over the world, Mitsubishi Electric Corporation (TOKYO: 6503) is a recognized world leader in the manufacture, marketing and sales of electrical and electronic equipment used in information processing and communications, space development and satellite communications, consumer electronics, industrial technology, energy, transportation and building equipment. The company recorded consolidated group sales of 3,645.3 billion yen (US$ 43.9 billion*) in the fiscal year ended March 31, 2011.

*At an exchange rate of 83 yen to the US dollar, the rate given by the Tokyo Foreign Exchange Market on March 31, 2011.

New protective collars for emergency stop pushbuttons prevent
stoppages to process-critical plant and machinery in hazardous environments

COOPER Crouse-Hinds, a leading manufacturer of explosion-protected electrical equipment, has launched a new range of protective collars for use on its Ex 41 series of explosion-protected pushbutton actuators.

The new metal protective collar attachments are suitable for use on COOPER Crouse-Hinds' GHG41, GHG43 and GHG44 series of emergency stop pushbuttons and enclosures, which are designed for use in hazardous gas or dust environments.

Once fitted to the EX 41 pushbutton actuator, the collars prevent machine operators or plant personnel from inadvertently activating the emergency stop button, which if pushed, could lead to costly downtime of the plant process or could increase the risk of injury to plant personnel.

Protective collars for use on its Ex 41 series explosion-protected pushbutton actuators.

The collars are designed in such a way that inadvertent operation of the pushbutton is impossible. Two cut-outs in the collar enable easy, rapid release of the pushbutton. Depending on the particular design of the actuator, release is activated either by a key or manually by simply turning/pulling the button. The collars are also available as a retrofit kit. The collars are designed for use in ambient temperatures from -55 Deg C to +55 deg C. The collars are available in two colours: red or yellow, to suit every emergency or safety installation requirements.

Gordon Low, Marketing Segment Manager at COOPER Crouse-Hinds UK Ltd comments: "The new protective collars can be retrofitted quickly and easily to existing emergency stop pushbuttons, without drilling any holes, which may adversely affect the Ingress Protection rating of the enclosure or pushbutton panel. This enables faster, more economical assembly for end users, whilst also guaranteeing the safety of machine operators and preventing unwanted stoppages to critical production processes or machinery, particularly on oil, gas and petrochemical plants and other high value, process-critical manufacturing environments."
