20080240720 | Terminal device, center device, optical communication network system and upstream signal timing control method - An upstream signal timing control method which controls a timing of an upstream optical signal, from a terminal device to a center device, to a timing that the center device intends. Optical clock pulses synchronized with the timing that the center device intends are sent from the center device to the terminal device. The terminal device delay-controls the optical clock pulses and retransmits them to the center device. The center device detects an offset between the timing and a timing of the returned optical clock pulses, and applies timing offset information to the transmitted optical clock pulses. The terminal device performs the delay control in accordance with the timing offset information applied to the received optical clock pulses. When the offset between the timing and the returned optical clock pulse timing is at or below a threshold, the center device verifies completion of timing control of the upstream optical signal. | 10-02-2008 |

20100080564 | Optical phase locked loop - A single sideband modulator uses a radio-frequency signal output by a voltage controlled oscillator to modulate a reference optical signal output by a local light source, thereby obtaining several sideband signals, and combines the sideband signals into a single reproduced optical signal. The optical coupler couples the reproduced optical signal with a received optical signal to generate an optical beat signal, from which a photoelectric transducer and loop filter generate a control voltage for the voltage controlled oscillator. These components operate as an optical phase locked loop that efficiently locks the reproduced optical signal in frequency and phase with the received optical signal by using the energy of all sidebands of the reference optical signal. The phase locked loop is useful for coherent detection of the received optical signal. | 04-01-2010 |
20110008061 | Synchronous circuit for use in optical homodyne receiver for generating local oscillation light with accurate demodulation - In a synchronous circuit, a synchronizing signal generator combines either an optical BPSK signal or local oscillation light with a phase-shifted signal to produce different optical signals, one of which for use in producing a signal demodulated from the BPSK signal is square-law detected, and calculates the optical signal detected to convert the signal into an electric signal. The generator produces an electric phase-locking signal which will be a demodulated signal from the BPSK signal on the basis of the electric signal. The phase-locking signal is used as a modulating signal by an intensity-modulating circuit to modulate an incident continuous light into an optical intensity-modulated signal, which is optoelectrically converted and square-law detected by an optoelectric converter. The converted signal is used by an optical VCO circuit as a phase error signal to adjust the phase or frequency of the local oscillation light, which is supplied to the signal generator. | 01-13-2011 |
