Fujitsu Quantum Devices, Nortel Networks agree on joint specifications of 10Gbps receiver devices

Aug. 23, 2001--With various kinds of 10 Gbps receiver modules in the market (package outline, pin assignment, shape of high speed signal input/output), there have been no standards for these types of devices.

Nortel Networks (NYSE/TSE: NT) and Fujitsu Quantum Devices, Ltd. have agreed on joint specifications for high-performance receiver devices for use in 10 gigabits-per-second (Gbps) optical communications products.

Optical receivers are electronic components that receive optical signals propagated down an optical fiber and change them into electrical signals. These receivers must have wide bandwidth and high sensitivity in order to realize high quality performance in ultra high speed (10 Gbps and up) optical telecommunications systems.

With various kinds of 10 Gbps receiver modules in the market (package outline, pin assignment, shape of high speed signal input/output), there have been no standards for these types of devices. The receiver modules in this agreement contain an Avalanche Photo Diode (APD) and a broadband, low-noise preamp integrated in a small package with SMP connectors.

This agreement on joint specifications between Fujitsu Quantum Devices and Nortel Networks provides customers with two sources for high-performance devices with common package outline and pin allocation for common board layout. The new receiver devices are designed to meet the requirements of the OC-192 SONET and STM-64 SDH (Synchronous Digital Hierarchy) standards.

Sample products are expected to be available in October 2001, and volume production is expected to start in January 2002.
