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, 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]
