Title: Automatic frequency control system
Inventor: ATOZAWA MIZUMASA
IPC: H04B10/516
Filed: 1992-04-30
Abstract: PURPOSE:To hold the frequency of a local oscillation light source at the value right before a break of light input is detected if the light input break is temporarily detected and to put the system back to stable frequency control immediately when a light signal is inputted again regardless of the temporary light input break. CONSTITUTION:When the input signal is temporarily ceased, the output signal of a frequency discriminator 10 also becomes zero, but a timing extracting circuit 14 detects a decrease in the clock component from the base band signal inputted from an input terminal 14a. Consequently, an alarm signal as a light input break signal is inputted from a terminal 14c to the input terminal 15b of a local oscillation light source control circuit 15. The circuit 15 outputs a control signal from an output terminal 15c to a memory 16 and reads ambient temperature and an applied current value corresponding to the frequency value of a local oscillation light source 2 right before the alarm signal is outputted out of a memory 16. Then a control signal which holds the frequency of the local oscillation light source right before the alarm signal is outputted is outputted from a terminal 15d. Consequently, the frequency of the light source 2 is continuously held at the value right before the input break and the control is started when the signal is inputted again.

IPC: H04B10/07
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of noise proofing ratio and to attain a low cost in a receiver by detecting the carrier wave level of polarization plane modulated signal light which is received by means of respective optical receivers, adding demodulated signals outputted from the respective optical receivers through a signal demodulator in proportion to the carrier wave level and cancelling the addition concerning the demodulated signal with the low carrier wave level at this time. SOLUTION: The carrier wave level of an optical strength fluctuating signal which is outputted from the optical receivers 1 is detected by carrier wave level detectors 4. At the time of the high carrier wavelevel, the attenuation quantity of a variable attenuator 5 is set small by a control signal to be outputted to the attenuator 5. The lower the carrier wave level becomes, the larger the attenuation quantity of the attenuator 5 is successively set. When the carrier wave level becomes less than a set value, the attenuation quantity of the variable attenuator 5 is set to the max., the control signal is outputted to a change-over equipment 6 and the change-over equipment 6 is changed-over to be in a service interrupting state. Then, a base band signal to be inputted is not outputted to an adder 7 so that only another base band signal is outputted through the adder 7.
