Semi companies bet on optical connects to solve last-mile chip interconnect issues. Intel and Ayar are using optical interconnect and chiplet technology for an FPGA. Ayar Optical interconnects have been lurking in the background in recent years as potential solutions to the issue of interconnecting. I. INTRODUCTION Today's communication systems critically rely on digital signal processing (DSP) algorithms to compensate for different channel impairments. However, the increasing. Mode division multiplexing (MDM) using multimode fibers (MMFs) is key to meeting the demand for higher data rates and advancing internet technologies. However, optical transmission within MMFs presents challenges, particularly due to mode crosstalk, which complicates the use of MMFs to increase. Abstract: Fiber optic communication is the main communication mode of data communication system nowadays, and its performance directly affects the quality of data communication system., what level of error. To obtain pulsed light signal used as pulsed pump light for optical fiber sensing and communication systems, a design scheme of generating pulsed light based on continuous laser and Field Programmable Gate Array (FPGA) is proposed in this paper. The pulsed light signals with minimum pulse width of.
