History
Zhone Technologies was founded in September 1999 by former executives of Ascend Communications, Jeanette Symons, Mory Ejabat and Robert Dahl.[1] The company was backed by former Lucent Technologies executive Richard McGinn.[2] It got investments from various venture capital businesses.[3]
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.[4][5]
In 2000, Forbes magazine noted "direct competition with Zhone, for now, is scarce, or at least unorganized."[6] Zhone co-founder Symons died in a plane crash in February 2008.[7]
The company was known as DZS between 2020 and 2025
