DFB laser diode transmitter module uses a 1.55 µm single-mode fiber pigtail for directly modulated digital optical communication. The module supports operation in 2.5 Gb/s high-speed transmission and dense-WDM systems with wavelength-selected ITU-T channel spacing. It integrates a bias circuit, optical isolator, thermoelectric cooler, thermistor, and monitor photodiode in a butterfly package. The M69 channel corresponds to a nominal 1553.33 nm center wavelength, with operation specified from -20 °C to 70 °C case temperature.
