Tellium

Optical Cross-Connect

Early in the DWDM revolution, Tellium was one of the first companies to recognize the need for an Optical Cross-Connect. Somewhat paradoxically, this was achieved with electro-optical conversions and high-bandwidth circuit-switching. Telliium originated via the spinout of a Bellcore research group which included Chuck Brackett, Krishna Bala, John Gamelin and others, and went public in 2001. Tellium was acquired by Zhone Technologies in 2003.
