Tokyo-based Mitsubishi Electric Corp has begun shipping samples of a DFB-CAN distributed feedback laser diode with built-in wavelength monitor. The new light source — reckoned to be the industry’s first to use the inexpensive TO-56CAN package (often used for low-speed optical signals, such as passive optical networks) 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...
