Title: Optical regeneration method and device for system transmitting non-soliton signal by optical fiber
Inventor: DESURVIRE EMMANUEL
IPC: H04B10/18
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To correct jitter noise, phase noise and the amplitude noise of a non- soliton RZ signal and to increase transmission rate or transmission distance by compressing an RZ signal into a signal of soliton type, synchronously modulating the signal of the soliton type and expanding a modulation soliton signal into the non-soliton RZ signal.

A modulation means 2 branches a part of the signal and adds it to a clock restoration device 7. A remainder is supplied to the input of a filter 8 through a coupler 6. A modulator 9 is controlled by the clock of the clock restoration device 7. The modulator 9 modulates the phase or intensity of the signal of the soliton type and transmits it to an expansion means. The signal of a reproduction soliton type is received by the output of the filter 12 and it is converted into the non-soliton RZ optical signal. Transmission rate is improved without changing transmission medium by appropriately selecting the dispersions of the optical fiber.

Abstract: PURPOSE:To reduce cross-talk noise which may be introduced from power source pins into input pins, by arraying near pins of a first power source, pins of a second power source independent of the first power source. CONSTITUTION:In arraying power source pins of an LSI, power source pins VCC1, VCC2, VEE, VTTL are connected to respective terminals VCC1, VCC2, VEE, VTTL of ECL output circuits 7-11 in the LSI 5. The ECL output circuit 7 includes mainly current switching transistors Q1, Q2, a constant-current driving transistor Q4 for supplying constant current, and an output emitter follower transistor QEF for outputting a signal from the LSI. Cross-talk noise owing to the mutual inductance LM1 between the self inductance L2 of the power source pin VCC1 and the self inductance L2 of the power source pin VCC2 in the power source pin arrangement, is insignificant. So is the case where another power source pins VTTL, VEE outside of the pin VCC2 are arrayed near the power source pin VCC1.
