    Area of Science:

    • Optical Communications
    • Fiber Optics
    • Signal Processing

    Background:

    • Long-haul optical transmission systems are crucial for modern telecommunications.
    • Few-mode fiber (FMF) offers increased capacity but requires advanced emulation techniques for testing.
    • Existing methods for emulating long-haul FMF transmission can be complex and costly.

    Purpose of the Study:

    • To present a novel optical chopper-based re-circulating loop.
    • To emulate long-haul transmission characteristics in few-mode fiber (FMF).
    • To validate the performance of the developed emulation system.

    Main Methods:

    • An optical chopper was integrated into a re-circulating loop setup.
    • Few-mode fiber (FMF) was used as the transmission medium.
    • Three-mode-division multiplexed (MDM) dual-polarization quadrature phase-shift keying (DP-QPSK) signals were transmitted.

    Main Results:

    • The re-circulating loop successfully emulated long-haul transmission conditions.
    • Data transmission of 128 Gb/s DP-QPSK signals over 1000 km of FMF was achieved.
    • The proper functioning of the loop was verified through successful data transmission.

    Conclusions:

    • The optical chopper-based re-circulating loop is a viable method for emulating long-haul FMF transmission.
    • This technique can facilitate the testing and development of future high-capacity optical networks.
    • The system demonstrates potential for cost-effective and efficient FMF system evaluation.
