The story

Zhone Technologies was founded in September 1999 by former executives of Ascend Communications, Jeanette Symons, Mory Ejabat and Robert Dahl. The company was backed by former Lucent Technologies executive Richard McGinn. It got investments from various venture capital businesses.

In 2000, New Enterprise Associates invested 55 million USD, CalPERS 50 million USD, Texas Pacific Group 150 million USD and KKR also 150 million USD. Some people from Ascend invested 50 million USD.

In 2000, Forbes magazine noted "direct competition with Zhone, for now, is scarce, or at least unorganized." Zhone co-founder Symons died in a plane crash in February 2008.

In 2016, it merged with DASAN Network Solutions and became DASAN Zhone Solutions Inc. In 2020, it moved its headquartered from the San Francisco Bay Area to Plano. In August 2020, Charlie Vogt was named CEO and DASAN Zhone became DZS.

On March 14, 2025, DZS announced that they had filed for Chapter 7 bankruptcy.

On April 7, 2025, Canadian telecommunication provider MNSi Telecom announced to acquire the assets of DZS. That transaction was concluded on May 5, 2025 when the newly re-formed Zhone Technologies Inc. acquired substantially all of the assets of DZS.
