Product Description
Low water peak dispersion unshifted single-mode optical fiber (G.652.D) is applicable to transmission systems operating over the entire wavelength from 1260 to 1625nm, which maintains low attenuation at 1383nm, thus making full use of E-band (1360-1460nm).
It optimizes attenuation and dispersion across the entire wavelength from1260 to 1625nm, reduces bending loss at the wavelength of 1625nm, provides more bandwidth resources for backbone, metropolitan area , and access networks.
Product Standard
ITU-T recommendation G.652.D
IEC 60793-2-50 B1.3 optical fiber specifications.
Product Characteristics
Designed for operation over the full optical spectrum from 1260 to 1625nm, hence the transmission capacity is increased. Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM. Accurate geometrical parameters ensure low splicing loss and high splicing efficiency. Excellent PMD satisfying high bit-rate and long distance transmission requirements.
