Tunable Optical Transmitter Breaks Size Barriers January 28, 2008
Self-crowned as the smallest, widely tunable transmitter optical subassembly (TOSA) for the dense wavelength division multiplexing (DWDM) transceiver market, the company's latest TOSA promises to bridge the gap for tunability and pluggability absent in its previous transceivers. Supporting 50-GHz channel spacing in metro networks, the component brings full-band tunability, or the ability for service providers to change to any wavelength on demand, to pluggable small form factor transceivers that commonly support one to two wavelengths. Additionally, the TOSA relies on the company's Laser Mach Zehnder (ILMZ) chip, a photonic IC that combines a tunable laser and optical modulator on a chip. For more details, call JDSU, Milpitas, CA.
