NTT Presents a Certificate of Appreciation to SANWA

Sanwa was presented with a certificate of appreciation from Nippon Telegraph and Telephone Corporation for its contribution to the IEEE Milestone Certification.


Nippon Telegraph and Telephone Corporation (“NTT”) has been recognized by IEEE, the world’s largest academic society in the field of technology, as a world-renowned “IEEE Milestone” for its development of “Physical Contact Push-Pull Technology for Fiber Optic Connectors”.

Mr. Akira Okada, Ph. D., Vice President, Head of NTT Device Technology Laboratories visited the Sanwa’s Tokyo Head Office and presented a certificate of appreciation from Mr. Jun Sawada, President and Chief Executive Officer, Representative Member of the Board of NTT and a commemorative gift (Replica of the IEEE commemorative plaque) to Yasuo Ishii, President and CEO of Sanwa, for Sanwa’s contribution to the development and dissemination of the optical fiber connectors adopting physical contact push-pull fastening technology.

Physical contact connection technology, the core of optical connectivity solutions, is used in various types of optical connectors as an international standard (IEC 61755-3-1, IEC 61755-3-31, -32) and has become the de facto standard in optical communications worldwide. The SC connectors and MPO connectors that laid the foundations are widely used in the ever expanding global optical fiber networks from backbone networks and access networks to data centers.

We will continue to make concerted efforts to contribute to brightening the future of the world.
