1962

Started production of IRRAX TUBE.

IRRAX TUBE is a trade name of non-shrinking tubings made of polyethylene, PVC, and other materials and irradiated with electron beams. They have excellent resistance to heat, wear, and flame. IRRAX TUBE is widely used for internal wiring of electronic appliances and computers.

The Head Office was moved from Osaka's Konohana Ward to the present address in Chuo Ward.

1963

Entered into the business of traffic control systems.

Entered into the business of traffic control systems.

Through research on leaky coaxial cables for railway communications, Sumitomo Electric embarked on development of computerized traffic control systems. Sumitomo Electric's control systems are used in many places, including the world-largest traffic control center at the Tokyo Metropolitan Police Department.

1969

Established its first overseas production facility (Siam Electric Industries Co., Ltd.)

Started production of flexible printed circuits (FPCs).

1970
Started production of compound semiconductors.

Started production of compound semiconductors.

Sumitomo Electric focused attention on compound semiconductors'various outstanding features, and started manufacturing them. Compound semiconductors are used in wide applications, including photoemitter elements for optical communications and ICs/FETs for mobile communication equipment like cellular phone and PHS, and are materials essential to support the information age. A large increase in future demand is expected. Sumitomo Electric will play a big roll as the world's leading manufacturer of compound semiconductors.

1971

Opened the Kanto Works.

1974
Started production of optical fiber cables.

Started production of optical fiber cables.

Sumitomo Electric foresaw the arrival of the advanced information age, and started production of optical fibers that ensure quick transmission of large amounts of data. Utilizing its fiber optic technology, Sumitomo Electric is now Japan's leading manufacturer that develops and manufactures various optoelectronic products, ranging from communication devices to optical LAN systems that use these devices.

1976
Received an order for a large telecommunications network project in Nigeria.

Received an order for a large telecommunications network project in Nigeria.

Sumitomo Electric received an order for the installation of outdoor telephone cables for local telephone networks in two project areas (the largest among all six areas) at about 60 billion yen from the Nigerian Ministry of Communications. At that time, this contract was an unprecedentedly large local telephone network project won by one company.

1978

Delivered and put into operation the world's first bi-directional fiber optic CATV system "Hi-OVIS".

The operation start of "Hi-OVIS" received international attention as a next-generation system. Various services are provided by this system: television retransmission service (provides sharp images), studio broadcasting service (interactively connects individual households with a studio that provides original broadcast programs offered by a local government unit), video service (videos and movies can be viewed on demand), and still-frame image service (provides information such as traffic news).
