8.3 micron core diameter. A completely eliminating the 1400nm band of high attenuation (ie, zero water peak) singlemode fiber ZWP-SW. It can be transmitted in the wavelength range 1280nm to 1625nm whole. (CWDM) channel can support 16 low-cost CWDM. And can support up to 400 Dense Wavelength Division Multiplexing (DWDM) channel. Full-wave fiber consistent with ITU-T G.652.C standards, while supporting existing transmission equipment and applications. Supports 10Gb / s transmission 300 meters.
