Parallel data transmission using modulated vibration and Mach–Zehnder interferometer

In this study, we reveal the distinct frequency response of optical cables and internal fibers, and provide insight into parallel data transmission using modulated vibrating signals and Mach–Zehnder interferometers configured within optical cables. The results highlight the importance of selecting the appropriate vibration frequency for internal fibers. In addition, the results of evaluating the bit error rate characteristics of parallel data transmission using two carrier frequencies indicate that for reliable parallel data transmission, it is important to select carrier frequencies that are not affected by crosstalk.
