    摘要： A method for reducing energy consumption of a passive optical network includes optical network units of the network which infer their downstream queue status rather than being explicitly notified by an optical line terminal of the network. Based on the inferred queue status, the optical network units make their own sleep mode decisions without assistance from optical line terminal. Both downstream traffic inference and sleep decision making at the optical network units are based on common information possessed by optical line terminal and optical network units. Accordingly, the optical line terminal can accurately infer the status of each optical network unit if the sleep control scheme implemented at an optical network unit is known by the optical line terminal.

    摘要： Systems and methods are disclosed for providing media access control (MAC) in an optical network by providing a separate control channel and data channel; dedicating each optical network unit (ONU) with one control channel, wherein the control message is transmitted at any time without constraints; sending a grant message to an ONU just before an allocated time is about to start; and sending data traffic from the ONU immediately after receiving the grant message without synchronizing with an optical line terminal (OLT) clock.

    摘要： A system and method for detecting a defect in an actuator arm conductor coil is disclosed. An actuator arm including a conductor coil is received. The conductor coil is coupled with a voltage as an anode. The conductor coil is submerged into a first solution, the first solution having no organic matter therein. The first solution is then coupled with a second solution including an organic indicator. The second solution also includes a cathode coupled to the voltage such that a defect in an insulation layer of the conductor coil is indicated by the organic indicator.
