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 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. These products and services include communication infrastructure equipment that uses optical and wireless information communication technologies and network camera systems that utilize 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
  • Waste reduction and management

Executive Officer
In Charge of Communication Systems Group

Telecommunication network systems that incorporate optical and wireless information communication technologies and network camera systems that utilize imaging technologies such as video content analysis and image recognition 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 is increasing rapidly.

Under these circumstances, the Communication Systems Group is striving to achieve greater energy savings and reduce environmental impact with a focus on four 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". Our optical and wireless access systems are used in automated meter readers for smart meters, while our communications gateway equipment is now being used in HEMS 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." We are producing network cameras that enable the reduction and reuse of communications cables.

Furthermore, as the fourth theme, we are simultaneously promoting the "reduction of CO2 generated during production and product shipping." We are also working to reduce energy consumption in 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 and utilize artificial intelligence and other such technologies to deliver high value-added systems to our customers. By doing so, we will contribute to expanding the communications and network camera markets, especially for security systems, and to mitigating environmental load.

Initiatives Contributing to the Environment and Society

Climate change Depletion of mineral resources Waste reduction and management Promotion of More Energy-Efficient and Compact Optical Access Systems

Subscriber equipment

The next-generation GE-PON ONU subscriber equipment for optical access systems uses a passive optical network (PON) that enables optical fibers to be shared among many users and realizes wide-band communications. It also achieves a 96% reduction in power consumption per traffic and 96% reduction in material usage compared to conventional equipment as a result of using parts that consume less power and reducing the number of parts in the equipment.

Climate change Providing Equipment That Delivers Energy Management Services

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.

Waste reduction and management Promotion of the Reduction and Reuse of Communications Cables

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

Climate change Depletion of mineral resources Waste reduction and management Environmental Assessment Evaluations

We require environmental assessments for all new product development projects. These assessments help us to make products and packing boxes more compact and simplify packaging.

Climate change Waste reduction and management Expanding Environmental Management to the Supply Chain

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.

Climate change Ongoing Reductions in CO2 Emissions during Production

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.

Proper management of chemical substances Waste reduction and management Koriyama Factory – Reduced Use and Appropriate Handling of Chemicals Such as Organic Solvents

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.

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

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.
