Small transceivers receive full
tunability
JDSU's TOSA brings full band tunability to pluggable small form factor transceivers that previously only supported one to two wavelengths.
JDSU has created the world's smallest widely tunable transmitter optical subassembly (TOSA) for the dense wavelength division multiplexing (DWDM) transceiver market The TOSA represents a dramatic reduction in size and cost compared to previous discrete solutions for tunable transmitters

Visible solid-state laser adopts telecomms design
The FCD488 is the first telecomms-based visible solid-state laser designed for biomedical, industrial and semiconductor applications.
The 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 tunable TOSA will enable service providers to use pluggable small form factor products to support 50GHz 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, which was released 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.
