JDSU develops world's smallest tunable optical transmitter

January 29, 2008, Milpitas, CA--JDSU, provider of communications test and measurement solutions and optical solutions for medical/environmental instrumentation, semiconductor processing, display, and other applications, has created the world's smallest widely tunable transmitter optical subassembly (TOSA) for the dense wavelength division multiplexing (DWDM) transceiver market. The new TOSA represents a dramatic reduction in size and cost compared to previous discrete solutions.

January 29, 2008, Milpitas, CA--JDSU, provider of communications test and measurement solutions and optical solutions for medical/environmental instrumentation, semiconductor processing, display, and other applications, has created the world's smallest widely tunable transmitter optical subassembly (TOSA) for the dense wavelength division multiplexing (DWDM) transceiver market. The new TOSA represents a dramatic reduction in size and cost compared to previous discrete solutions for tunable transmitters.

The new TOSA brings full band tunability, or the ability for service providers to change to any wavelength on demand, to pluggable small form factor (XFP) transceivers that previously only supported one to two wavelengths. In addition, the new tunable TOSA will enable service providers to use pluggable small form factor products to support 50 GHz channel spacing in metro area networks, as traffic continues to grow in this area due to increased use of voice, video, and data applications among consumers. According to a recent report by analyst firm IDC, fastest growth in optical networking is expected in the metro space over the next three years.

The TOSA houses JDSU's Integrated Laser Mach Zehnder (ILMZ) chip that was announced in September 2007. The ILMZ is a photonic integrated circuit (PIC) that combines a tunable laser and optical modulator on a tiny chip for smaller, higher performance tunable solutions. JDSU produces the ILMZ using a semiconductor style of manufacturing that allows this functionally integrated optical solution to be produced in high volumes more quickly and efficiently, resulting in lower costs.
