New DFB-LD and APD from Mitsubishi Electric for 10GEPON

DFB-LD
The new distributed feedback laser diode ML7xx42 incorporates an AlGaInAs active layer providing 10mW of output power under low operating current even in high-temperature conditions. Due to an improved modulation bandwidth it is able to perform smoothly at 10Gbps. The DFB-LD is housed in a TO-CAN package with a diameter of 4.8mm and equipped with an aspherical lens cap providing a high coupling efficiency. ML7xx42 has its light emission peak at a wavelength of 1,270nm while the output power is 10mW at operating currents of less than 70mA. It is designed for the operating temperature range from -5 to +75°C.

APD
Mitsubishi Electric utilizes AlInAs for the multiplication layer of the new low-noise avalanche photodiode which provides an industry leading sensitivity of typically 31.5dBm. Packaged in a 5.4mm TO-CAN with a ball lens cap, the PD8xx24 operates in the 1,570nm wavelength band and has an APD responsivity of typically 0.8A/W, together with a bandwidth of typically 6.5GHz.
