Low-water-peak non-dispersion-shifted single-mode fiber is suitable for 1260-1625nm full-band transmission systems. It suppresses the water peak loss caused by the absorption of hydroxide ions (OH-) in the ordinary single-mode fiber near 1383nm, and expands the working window to the E-band (1360-1460nm), thereby increasing the spectral bandwidth of about 100nm. The fiber fully optimizes the attenuation and dispersion characteristics of the full band of 1260-1625nm, and improves the macro-bend resistance of the L-band (1565-1625nm), which fully meets the needs of multi-channel transmission of high-rate services on a single fiber.
Applications
Optical fiber has a wide spectral bandwidth and superior optical characteristics. It supports different transmission technologies such as Ethernet, Internet Protocol (IP), Asynchronous Transmission Mode (ATM), Synchronous Optical Network (SONET), and Wavelength Division Multiplexing (WDM). The best choice. Optical fiber provides greater bandwidth resources for backbone networks, metropolitan area networks, and access networks, and meets the requirements for bandwidth resources for voice, digital, and image transmission services.
Optical fiber is suitable for various types of optical cable structures, including optical fiber ribbon cable, loose-layer twisted-type optical cable, skeleton-type optical cable, center-beam tube-type optical cable and tight-type optical cable.
Product Standards
Low-water peak single-mode fiber meets or exceeds ITU-T G.652.D and IEC 60793-2-50 B1.3 fiber specifications.
YOFC has set stricter standards for various indicators of optical fiber products.
