High Performance Design of 100Gb/s DPSK Optical Transmitter

摘要

High performance communication systems require high performance devices for exchanging information at a faster rate. These devices are experiencing several challenges e.g. bandwidth limitations, power limitations, design limitations and etc. The existing techniques are lacking in providing high performance output simultaneously by maintaining actual parameters of device. In this work, high performance 100Gb/s optical DPSK transmitter design is realized in Field Programming Gate (FPGA) using time constraint technique. Before applying the proposed technique actual FPGA’s frequency was 0.2 GHz and optical transmitter have taken plenty of time for transmitting signal. When proposed design is operated at 1 GHz, 5 GHz, 10 GHz and 20 GHz using time constraint technique, it is observed that among all these frequencies, at 10 GHz high performance output is achieved for designed optical transmitter. This high performance design of optical transmitter has zero timing error, low timing score and high slack time due to synchronization between input data and clock frequency. It is also determined that 99% timing score is reduced in comparison with 1 GHz frequency that has high jitters, high timing error, high time score and low slack time. The high performance design is realized without disturbing actual bandwidth, power consumption and other parameters of the design. The proposed high performance design of 100Gb/s optical transmitter can be used with existing optical communication system to develop high performance communication system for future generation networks.
