Mitsubishi sampling DFB-CAN with built-in wavelength monitor for digital coherent communication
Mitsubishi to start shipping sampling of its latest optical device, a DFB1-CAN with built-in wavelength monitor from 1st Apr 2024.
Mitsubishi said this innovative new light source is the industry’s first to use the TO-56CAN 3 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 modules and related components that combine small footprints and low power consumption." explains Mitsubishi in its rele...
