Bookham Demos 40G Tunable Transmitter

Bookham has demonstrated its 40 Gbps ODQPSK tunable transmitter capability to its Tier 1 customers.


The company said its tunable transmitter assembly (TTA) will meet price points that enable cost-effective deployment of 40Gbps transmission in metro networks. The TTA has been demonstrated in the Bookham Caswell, UK, facility using cascaded DWDM nodes to reproduce real network conditions, and will be sampled into customer premises next month.


The Bookham 40 Gbps portfolio of products utilizes the Optical Differential Quadrature Phase Shift Keying (ODQPSK) modulation scheme for 40 Gbps. http://www.bookham.com
