Summary:An optical transmitter chip based on OTN transmission technology, which solves the high bit error rate in existing OTN technology for data transmission below 100 m in the data center, includes a transmitter TX, a digital control unit DIGIITAL, and a power module POWER. The transmitter TX first uses the optical modulation amplitude signal loss module to complete a judgment of an optical modulation amplitude for an attenuated electrical signal transmitted through metal traces on a PCB board. Only if the signal is greater than the preset threshold, an enable signal is output to control a linear equalizer and a laser driver to start, and open a signal transmission path for the chip-driven laser to emit an optical signal. The linear equalizer and the bypass ByPass process signal optimization in two-stage, then the signal is sent to the laser driver to drive the laser to emit an optical signal.
