Cable Communications in Japan

Japanese coaxial toll systems at the end of the fiscal year 1970 had grown to 29 980 km of coaxial cable (including both tubes of two-tube systems). In the next seven years, 1971 to 1977, the requirement is expected to be three times this capacity. Cable transmission systems fully utilizing modem electronics and communication engineering techniques are being developed to best meet this expected growth and to provide new wider band services.
