    • The developed fiber exhibits a low optical loss below 0.4 dB/km at 1.3-1.55 microm wavelengths.
    • The zero-chromatic-dispersion wavelength was precisely measured to be 1.402 microm.

    Conclusions:

    • The triangular-profile single-mode fiber demonstrates excellent low-loss characteristics.
    • Its specific zero-dispersion wavelength makes it suitable for high-performance optical communication applications.
