Notification of changing company name

Thank you very much for your continuous support.

We changed our name from SEI Optifrontier Co., Ltd. to Sumitomo Electric Optifrontier Co., Ltd. on July 1, 2020.

We were established by merging Toyokuni Electric Cable Co., Ltd. and Sumiden High Precision Co., Ltd. in July 2010; since then we have carried on our business in cooperation with our parent company, Sumitomo Electric Industries, Ltd. (hereinafter referred to as Sumitomo Electric).

Thanks to you, we are celebrating the 10th anniversary of our establishment this year; in order for us to make a further leap forward in the information and communication market, where technological innovation and growth continue, we need to integrate with Sumitomo Electric and its technology. We thought that it was important to clearly indicate that the company is backed by strength, so we decided to change the company name to Sumitomo Electric Industries.

We, as an Optifrontier in the optical communication field, will push hard to contribute to the further development of the information communication society as a single body. Thank you in advance for your continuous support.

1. New company name/Sumitomo Electric Optifrontier Co., Ltd.
2. Revised date/July 1, 2020
∗Our address, telephone number, website and email address remain the same.
