Sub-Assemblies suit 10 Gbps optical fiber systems.

Press Release Summary:

Receiver Optical Sub-Assemblies optimize performance of 10 Gbps transceivers using electronic dispersion compensation. Multi-mode Model VSK10R07-06 incorporates photodetector with linear pre-amplifier for 1310 and 1550 nm systems. It features bandwidth of 8 GHz, sensitivity of -13 dBm, and dynamic range greater than 15 dB. Single-mode Model VSK10R09-06 operates at 1310 and 1550 nm and achieves sensitivity of -17 dBm, 19 dB dynamic range, and bandwidth of 8 GHz.

Original Press Release:

VSK Photonics' New 10 Gbps ROSA Product Line

October 14, 2003 - Lake Forest, CA - VSK Photonics, Inc. announces a line of receiver optical sub-assemblies (ROSAs) for 10 Gbps fiber optic communication systems. The new multi-mode and single-mode ROSAs are designed to optimize the performance of short reach 10 Gbps transceivers utilizing electronic dispersion compensation.

The new VSK10R07-06 ROSA for multi-mode incorporates a high-performance photodetector with a linear pre-amplifier to provide excellent performance in 1310 and 1550 nm systems. VSK's proprietary chip design enhances performance in multi-mode systems with off-axis launch. With a bandwidth of 8 GHz, a sensitivity of minus 13 dBm, and dynamic range greater than 15 dB, the VSK10R07-06 ROSA easily exceeds all performance requirements for OC192-SR1 transceiver modules.

The VSK10R09-06 ROSA specified for single-mode optical fiber systems operates at 1310 and 1550 nm. This new receiver optical sub-assembly achieves a sensitivity of minus 17 dBm, 19 dB of dynamic range, and a bandwidth of 8 GHz. The VSK10R09-06 ROSA exceeds all performance criteria for 10 Gbps Ethernet LR and ER transceivers, delivering performance comparable to more costly pigtailed receiver modules.

VSK's single- and multi-mode ROSAs are both available in 5 pin TO-46 headers with a cap and sleeve. Configured to mate with LC connectors, the cost effective packaging is designed to deliver optimum high-speed performance. Engineering samples are now shipping, with full production slated to begin in Q4 2003.
