| Zusammenfassung: | An optical transmitter apparatus includes a plurality of optical transmitter modules and a host controller. A module controller in each module determines whether the modulation current of a laser diode in the module is an anomaly, and also determines whether the temperature of the laser diode is an anomaly. If the modulation current or the temperature of the laser diode has an abnormal value, the module controller generates and sends an alarm signal from an alarm-outputting terminal. The alarm-outputting terminals of the modules are connected to an alarm-receiving terminal of the host controller in a wired-OR connection. |
