专利汇可以提供Optical transmission/distribution system专利检索,专利查询,专利分析的服务。并且PURPOSE: To linearize the response of an electro-optical modulator by superposing a pilot signal to an electric signal, monitoring the size of harmonic distortion or intermodulation and changing the non-linear transmission characteristics by an electric preliminary adjustment means.
CONSTITUTION: A transmitter system 900 is provided with a modulation means 902, an optical fiber distributing network 903 having one or more splatters and at least one optical receiver 905. In a method for linearizing the amplitude transmitting characteristic of an integrated optic device, a pilot signal is introduced, the contents of the harmonic distortion of an optical output are monitored and a bias signal is fed back to tune parametrically the operation points of the integrated optic modulator 902 and a predistortion network 906. Consequently, it is possible to realize a predistorition network 902 appropriately parametrically turntable.
