JDSU announced what it claims is the world's smallest, widely tunable transmitter optical subassembly (TOSA) for the dense wavelength division multiplexing (DWDM) transceiver market.

The new TOSA brings full band tunability to pluggable small form factor (XFP) transceivers that previously only supported one or two wavelengths.

The subassembly 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 due to increased use of voice, video and data applications among consumers.

The TOSA houses JDSU's Integrated Laser Mach Zehnder (ILMZ) chip that was announced in September. 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 will offer transceiver products leveraging the new TOSA package to the market later this year.
