Mitsubishi Electric to Ship Samples of DFB-CAN with Built-in Wavelength Monitor for Digital Coherent Communication

Small-package TO-56CAN will contribute to miniaturized, low-power consumption of optical transceiver modules

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that it will begin shipping samples of its latest optical device, a DFB-CAN with built-in wavelength monitor, on April 1. This innovative new light source, the industry’s first to use the TO-56CAN package for digital coherent communication capable of high-speed, long-distance transmission, is expected to contribute to the realization of ultra-small, low-power consumption of optical transceiver modules.

Communication traffic is growing rapidly due to advances in IoT technology, high-resolution video streaming, and generative AI technology, requiring networks to deliver ever-higher speeds and capacities. However, faster optical communication signal speeds can cause waveform distortion due to chromatic dispersion, which limits signal transmission distances. Digital coherent communication corrects such distortions using digital signal processing technology, allowing optical signals to be transmitted at higher speeds and over longer distances compared to conventional intensity modulation methods. In parallel, the use of optical transceiver modules is increasing as optical communication traffic grows. Both trends are driving demand for optical transceiver modules and related components that combine small footprints and low power consumption.

Mitsubishi Electric’s new DFB-CAN’s compact package includes a DFB laser chip and a wavelength monitor chip. Its unprecedented low-power consumption of only 1W was achieved by improving the thermal exchange element for temperature control in the DFB laser chip and optimizing the design for heat dissipation.
