Application 

The G.652.D single-mode optical fiber is not only widely used for voice transmission, data, video, and other services, providing customers with high-cost performance and quality products, but it also extensively serves major telecommunications carriers. It is suitable for building backbone networks, local networks, access networks, and large enterprise networks.


Characteristics

  • Lower water peak value

  • Exhibits lower PMD (Polarization Mode Dispersion) values

  • Operates within an extended wavelength range to the E-band

  • Suitable for low-cost coarse wavelength division multiplexing (CWDM) systems

  • Supports upgrades from CWDM to dense wavelength division multiplexing (DWDM) systems

  • Precise control of geometric dimensions, resulting in low fusion splice losses

  • Excellent coating protection with superior stripping performance
