摘要： A method of processing optical signals in a passive optical network includes receiving a first signal in a first optical spectrum, and receiving a second signal in a second optical spectrum. The second optical spectrum is different from the first optical spectrum. The method also includes multiplexing the first and second signals into a first multiplexed signal and outputting the first multiplexed signal. The method also includes receiving a second multiplexed signal, and demultiplexing the second multiplexed signal into a third signal and a fourth signal. The third signal is in the second optical spectrum and the fourth signal is in the first optical spectrum. The method also includes outputting the third and fourth signals.

摘要： Systems and apparatus for a wirelessly-powered passive optical power meter device. In one aspect, an optical power meter device comprises a power circuit connected to one or more antennas, the circuit including an RF to DC converter that generates a DC power signal that provides a DC power source for the optical power meter from an RF signal received by the one or more antennas, a photodetector that generates a power measurement signal that measures the power of the optical input signal, and a communication circuit that is connected to the one or more antennas, the photodetector, and the power circuit that when powered by the DC power source generates a modulation signal that is responsive to the power measurement signal and that causes the one of the one or more antennas to convey the power measurement signal to a reader device that is transmitting the RF signal.

摘要： A remote control for a set-top box is configured to communicate with the set-top box using first and second wavelengths. In one embodiment, the remote control automatically performs Bluetooth pairing with the set-top box when the remote control is in proximity to the set-top box and the user presses a button on the remote, such as a “Power” button or other designated button. The remote control may wirelessly transmit a unique ID to the set-top box for the pairing process using the first wavelength, such as infrared. When paired, the set-top box may accept commands from the remote control transmitted using the second wavelengths, e.g., Bluetooth.

摘要： A remote node includes a first node input, a second node input, and an optical switch. The optical switch includes a first switch input optically coupled to the first node input, a second switch input optically coupled to the second node input, a first switch output switchably coupled to the first switch input or the second switch input, and a second switch output switchably coupled to the first switch input or the second switch input. The remote node includes a photodiode optically coupled to the second switch output, and a capacitor electrically coupled to the photodiode and the optical switch. When the first switch input is switchably coupled to the first switch output, the second switch input is switchably coupled to the second switch output. Light received by the second switch input passes out the second switch output to the photodiode. The photodiode charges the capacitor to a threshold charge.

The first transmit-EDFA is operable between a respective enabled state and a respective disabled state. The second transmit-EDFA is optically coupled to the OLT and a second feeder fiber, and the second feeder fiber is optically coupled to a second RN. The second transmit-EDFA is operable between a respective enabled state and a respective disabled state.
