The G.652D and G.657A low water peak non-dispersion shifted single mode fiber is suitable for transmission systems with a full wavelength range of 1260 to 1625nm. The G.652D and G.657A low water peak non-dispersion shifted single mode fiber refrains low water peak loss around 1383nm which is thanks to the absorption of hydroxyl ions. The G.652D and G.657A low water peak non-dispersion shifted single mode fiber expands the working window to E-band(1360-1460nm), and so increases about 100nm spectra band width. The G.652D and G.657A low water peak non-dispersion shift single mode fiber overall optimizes the properties of fading and dispersion of 1260 to 1625nm full wave band, improves flexural behavior of L-band (1565-1625nm)and fully meet the requirements of multi-channel transmission and high speed operation.

The G.652D and G.657A low water peak non-dispersion shifted single mode fiber realizes transmission of full wave band of 1260 to 1625nm, increases spectra band width by 50% and improves capacity of system transmission. The superior optical property meets transmission requirements of high speed dense wavelength division multiplexing (DWDM) and coarse wavelength division multiplexing (CWDM) system. The G.652D and G.657A low water peak non-dispersion shifted single mode fiber is compatible with existing 1310nm transmission equipment and the coating has good protectiveness and superior stripping performance. The accurate geometrical parameters ensure low-loss splice and high-efficiency splice.

The low water peak non-dispersion shifted single mode fiber has very wide spectra band width and superior optical property, which is the best choice for supporting different transmission technologies such as Ethernet, internet protocols, asynchronous transmission mode, synchronous optical networking and wavelength division multiplexing system. The low water peak non-dispersion shifted single mode fiber provides greater broadband resources for backbone networks, metropolitan area networks and access networks and it meets the demand for broadband resource of voice, digital, image transmission and other operations. The low water peak non-dispersion shifted single mode fiber is suitable for all kinds of optical fiber cable structures, such as optical fiber ribbon cable, stranded loose tube cable, slotted core cable, central beam tube optical cable and tight buffered optical cable.
