TPC-1, the first telephone cable across the Pacific Ocean, was recognized as an "IEEE Milestone
.
" It is reported that the "IEEE Milestone" is a system that recognizes inventions and technology research and development that are outstanding in electronics, electrical, information and other related fields and have made great contributions to society, and the commended research and invention must take more than 25 years to be eligible for selection

It is reported that the telephone cable was built by KDDI of Japan and AT&T of the United States, and Hawaiian Telecom of the United States, and began operation on June 19, 1964, laying between Japan-Guam-Hawaii, with a total length of about 10,000 kilometers
.
The telephone cable was opened as a national-scale event in preparation for the Tokyo Olympics in October 1964 in preparation for the opening of the Shinkansen line on Japan's Tokai Island, with Japanese Prime Minister Ikeda and U.
S.
President Johnson making commemorative calls
.
In 1964, international calls were generally short-wave communications, with long connection times, many noises, and could not talk at the same time, and there were many problems, but the connection of TPC-1 telephone cables solved these problems
.
In addition, the "TPC-1" telephone cable has also become the basis for
the construction technology of optical fiber submarine cable in the future.
Because the opening of this cable has greatly contributed to the major communication infrastructure technology in the current Internet era, it has been recognized as an "IEEE milestone"
.
Following the "Trans-Pacific Satellite TV Broadcast (Ibaraki Satellite Communication Center)" in November 2009 and the "International Standardization of G3 Fax" in April 2012, the "TPC-1" telephone cable undertaken by KDDI has been recognized as an "IEEE Milestone" for the third time, and the same individual/group has won three honors, the first time
in Japan.
