Abstract: The invention provides a device and a method for extending the bandwidth of short wavelength and long wavelength fiber optic lengths. The invention provides for an optical transmitter package device comprising: a laser diode; and a semiconductor optical amplifier connected directly after and in close proximity to the laser diode, wherein the semiconductor optical amplifier is adapted to operate in a frequency domain such that the semiconductor optical amplifier filters and reshapes optical wavelengths from the laser diode, and wherein the semiconductor optical amplifier is biased below an amplification threshold for the semiconductor optical amplifier. The device may also comprises a feedback circuit which comprises an optical splitter, wherein the feedback circuit samples reshaped optical output from the semiconductor optical amplifier and dynamically adjusts one or both of the semiconductor optical amplifier and the laser diode. In the case of a multimode fiber, the present invention provides the additional ability to provide a controlled offset launch into the fiber and the ability to control modal noise devoid of a specialized optical connector.

Abstract: Ein Verfahren und eine Steuereinheit zur Steuerung der Energieverwaltung verringern den Aufwand für den Stromversorgungsstrom und/oder die Teilsystemkühlung, der den Wirkungsgrad des Systems verringert, die Systemzuverlässigkeit verringern kann und das Umgebungsgeräusch erhöhen kann. Mehrere Einheitensteckverbinder werden von entsprechenden Softswitches mit Strom versorgt, die so programmiert sind, dass sie einen Strompegel bereitstellen, der ausreichend ist, um den Höchststrom für die in dem entsprechenden Einheitensteckverbinder installierte Einheit zu liefern. Der Strompegel kann aus von der Einheit während der Initialisierung bereitgestellten Informationen über die Einheit ermittelt werden, die eine Höchststromanforderung direkt festlegen können. Alternativ kann die Höchststromanforderung aus anderen die Einheit identifizierenden Informationen wie einer eindeutigen Einheitenkennung ermittelt werden. Als Folge dessen können ein garantierter Höchststrom bzw. eine elektrische Leistung und eine Verlustleistung ermittelt werden, und mehrere Stromversorgungen und/oder Kühleinheiten wie Luftbewegungseinheiten (AMDs) können entsprechend aktiviert, deaktiviert oder anderweitig gesteuert werden.

Abstract: An energy management control method and controller reduce power supply current and/or subsystem cooling overhead that reduces system efficiency, may reduce system reliability and may increase ambient noise. Multiple device connectors are supplied from corresponding soft switches that are programmed to provide a current level that is sufficient to supply the maximum current for the device installed in the corresponding device connector. The current level may be determined from device information provided from the device during initialization, which may directly specify a maximum current requirement. Alternatively, the maximum current requirement can be determined from other device- identifying information such as a unique device identifier. As a result a guaranteed maximum current or power and power dissipation can be determined, and multiple power supplies and/or cooling devices such as air movement devices (AMDs) may be enabled, disabled or otherwise controlled accordingly.
