Low water peak non dispersive shifted single-mode fiber is suitable for transmission systems in the entire wavelength range of 1260-1625nm. It suppresses the water peak loss caused by hydroxide ion (OH -) absorption in ordinary single-mode fibers around 1383nm, expands the working window to the E-band (1360-1460nm), and thus increases the spectral bandwidth by about 100nm. The optical fiber has comprehensively optimized the attenuation and dispersion characteristics of the entire 1260-1625nm band, and improved the anti bending performance of the L-band (1565-1625nm), fully meeting the demand for multi-channel transmission of high-speed services on a single optical fiber.
Product Application
With wide spectral bandwidth and superior optical characteristics, optical fiber is the best choice to support different transmission technologies such as Ethernet, Internet Protocol (IP), Asynchronous Transfer Mode (ATM), Synchronous Optical Network (SONET) and Wavelength Division Multiplexing (WDM). Quanbei ® Fiber optic provides greater bandwidth resources for backbone networks, metropolitan area networks, and access networks, meeting the bandwidth requirements of various services such as voice, digital, and image transmission.
Fiber optic cables are suitable for various types of optical cable structures, including fiber ribbon cables, loose layer twisted cables, skeleton cables, central bundle tube cables, and tight fitting cables.
Product Standard
Low peak single-mode fiber meets or exceeds ITU-T G.652. D and IEC standards; 60793-2-50 B1.3 Optical Fiber Technical Specification.
