Abstract: Components, systems, and methods for determining efficiency of an optical signal source in distributed communication systems are disclosed. Environmentally induced variations in the performance of optical sources used to convert electrical signals to optical signals (such as laser diodes) at the transmitters within the system can be evaluated in real time. Steps can be taken to compensate for these variations. The efficiency of the laser diode can be measured and provided to receivers in the distributed communication system. The receiver may use information related to the slope efficiency measurement to adjust the gain of the receiving amplifiers to provide desired adjustments to the gain. Thus, the receivers in the remote units (RU) receive information about the slope efficiency of the laser diodes at the head end equipment (HEE) and the HEE receives information about the slope efficiency of the laser diodes at the RU.

Abstract: A data storage device includes a non-volatile memory and host interface circuitry. The host interface circuitry is configured, in response to receiving a first command from a host device, to access a table to determine whether to reject the first command based on an operating state of the data storage device. The data storage device also includes a processor coupled to the non-volatile memory and to the host interface circuitry. The processor is configured to program the table.
