This standard specifies a semiconductor laser module for optical transmission used as a light source (having an optical fiber pigtail or a receptacle for connecting an optical fiber, and as necessary, incorporating simple elements such as a photodiode for monitoring, a thermoelectric cooler, a temperature sensor, and an optical isolator). It has a built-in
