Environment – Communication Systems Group

Business Overview and Environmental Issues for Which Risks and Opportunities Have Been Recognized and Evaluated

Providing Communications Equipment and Services That Contribute to the Advancement of the Information Society

The Communication Systems Group is contributing to the advancement of the information society through products and services supplied to customers such as communications carriers, financial services and retail distribution companies, and government agencies in Japan and overseas. These products and services include communications infrastructure equipment that uses optical and wireless information communications technologies (ICTs) and network camera systems equipped with imaging technologies. The field of telecommunications has seen dramatic advances in technology and changes in demand. To satisfy our customers, we are striving to develop cutting-edge technologies and build an efficient yet flexible production system, with the Koriyama Factory in Fukushima Prefecture and the Communication Networks Center in Amagasaki, Hyogo Prefecture as bases for those activities.

Environmental Issues for Which Risks and Opportunities Have Been Recognized and Evaluated

  • Climate change
  • Depletion of mineral resources
  • Proper management of chemical substances in design and manufacturing
  • Waste reduction and management

Message from Communication Systems Group

Contributing to the Development of Communications and Network Camera Markets, and Reducing Environmental Impact through Our High Value-Added Systems

Takashi Nishimura
Executive Officer
In Charge of Communication Systems

Telecommunication networks that incorporate optical and wireless ICTs and security systems that utilize imaging technologies such as Video Content Analysis (VCA) and Artificial Intelligence (AI) are key elements of the social infrastructure that is essential to our daily lives and the growth of industry. However, as these devices develop greater functionality and are used by more and more people, electricity consumption increases rapidly.

Under these circumstances, the Communication Systems Group is striving to achieve greater energy savings and reduce environmental impact with a focus on three core themes.

The first is "energy-­efficient products". Here, we are working on energy-­efficient designs for optical access systems used in communications infrastructure equipment and communications gateways (relays) for service providers.

The second is "achieving energy savings in services provided using our products". Here, our optical and wireless access systems are used in automated meter readers for smart grids, while our communications gateway equipment is now being used in HEMS/BEMS to help make it easier to monitor electricity use. We are also developing network equipment in the field of IoT, which supports production efficiency and reduced energy consumption.

The third is "environmental contributions during installation work". Here, we are producing network cameras for the reduction and reuse of communications cables.

At the same time, we are promoting a reduction of CO2 generated during production and product shipping. We are also working to reduce energy consumption in our factories and offices by updating to high-efficiency air conditioners and reducing standby power, and increasing shipping efficiency by improving freight loading efficiency and modal shift.

Going forward, we will continue refining our optical and wireless information communication technologies and imaging technologies while delivering high value-­added systems to our customers. This will enable us to help expand our communications and network camera markets, especially for security systems, around the world, while mitigating environmental impacts.

Initiatives Contributing to the Environment and Society

Promotion of More Energy-Efficient and Compact Optical Access Systems

Climate change
Depletion of mineral resources
Waste reduction and management

Subscriber terminal equipment for optical access systems

The GE-PON ONU customer network terminating unit for optical access systems uses a passive optical network (PON) to provide a single optical fiber connection to up to 64 users, which makes the unit more compact and energy-efficient. In addition, this unit achieves a 75% reduction in power consumption and 69% reduction in material usage compared to conventional units because of its use of low-power consumption parts and reduced number of parts.

Providing Equipment That Delivers Energy Management Services

Climate change

Gateway equipment

We supply gateway equipment for service providers that connects various household, factory, or building networks to an energy management system using the cloud. This equipment is used to obtain power consumption data from home appliances, air conditioning units, or production lines that is then used to deliver demand response services that strike a balance between electricity supply­-demand and energy management systems, such as HEMS.

Promotion of the Reduction and Reuse of Communications Cables

Waste reduction and management

We are working to reduce and reuse communications cables during installation work through production of the MELOOK3 (coaxial type) digital network camera system, which can use existing analog camera cables for high-definition and highly functional digital network camera systems without the need to lay new LAN cables for digital CCTV.

Initiatives for Reducing Environmental Impact

Environmental Assessment Evaluations

Climate change
Depletion of mineral resources
Waste reduction and management

We require environmental assessments for all new product development projects. These assessments are helping us to make products and packaging more compact and to reduce the amount of packaging materials we use.

Expanding Environmental Management to the Supply Chain

Climate change
Waste reduction and management

In addition to reducing CO2 during production and in product use, we are streamlining product transportation and reducing CO2 by improving loading ratios and introducing a modal shift*.

Modal shift: Switching from using truck transportation to marine or rail transportation, which can carry large volumes of goods and are environmentally friendly.

Ongoing Reductions in CO2 Emissions during Production

Climate change

At the same time as we are working to improve productivity by increasing the speed of the equipment and reducing cycle times through improvements, we are continuing to reduce energy consumption by replacing high energy consumption equipment and old air conditioners and lighting with high-efficiency types. Starting in fiscal 2017, we have been working to minimize the consumption of LPG (liquid petroleum gas) on the paint drying line, which consumes a large amount of energy.

Koriyama Factory – Reduced Use and Appropriate Handling of Chemicals Such as Organic Solvents

Proper management of chemical substances in design and manufacturing
Waste reduction and management

The Koriyama Factory is involved in every step of the manufacturing process from materials processing, including plate fabrication and molding, to product assembly. It has reduced the use of organic solvents by introducing a microbubble wash during the plate cleaning process and changing to powder paint solvents. Furthermore, as well as using risk assessments to keep track of the danger and harm of chemical substances, we conduct emergency training for potential emergency situations and work to prevent environmental accidents.

Communication Networks Center – Achieving Greater Energy Efficiency through Production Line Improvements

Climate change

The Communication Networks Center, which designs nearly all of the products made by the Communication Systems Group and assembles communications equipment, has improved its production line to more flexibly respond to changing demand from the marketplace, resulting in less space being used and improved productivity. As a result, the Center has significantly reduced the amount of electricity it uses for the lighting and air conditioning equipment necessary for production. In addition, the Center is reducing the energy used for utilities by its design and sales offices by upgrading to more efficient air conditioning and making operational improvements.
