Fiber G652D

G.652.D single-mode optical fiber is designed for transmission systems covering the entire wavelength range of 1260 to 1625nm. This single-mode fiber effectively mitigates water peak losses associated with hydrogen and hydroxide ion absorption near 1383nm, extending the operational window into the E-band (1360 to 1460 nm) and thereby increasing the spectral bandwidth by approximately 100 nm. The G.652.D single-mode optical fiber comprehensively optimizes attenuation and dispersion performance across the entire wavelength range of 1260 to 1625nm, meeting the demands for high-speed, multi-channel transmission on a single fiber. Therefore, the G.652.D single-mode optical fiber stands out as one of the best choices for constructing networks.

our company

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

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
