Detailed Photos Product Description G. 652.D single mode
optical fiber is designed specially for optical transmission
systems operating over the entire wavelength window from 1260nm to
1625nm. By suppressing the water peak that occurs near 1383nm in
conventional single mode fibre due to hydroxyl (OH-) ions
absorption, the fiber is able to open E-band (1360-1460nm) for
operation, and consequently provides 100nm more usable wavelengths.
It optimizes attenuation and dispersion across the
entire wavelength window from 1260nm to 1625nm, also reduces
bending loss at L-band (1565nm~1625nm), and provides
bandwidth resources for trunk, metropolitan area and access
network. Characteristics (1) Comply to or superior to
the ITU-T G.652D recommendation and IEC 60793-2-50 B1.3
specification.(2) Designed for operation over 1260nm to 1625nm
wavelength spectrum.(3) Outstanding optical performance supporting
high-speed transmission requirement of DWDM and CWDM.(4) Excellent
PMD performance, supporting high-speed and long repeater spacing
transmission system.(5) Compatible with existing 1310nm
equipment. Application (1) Application for all kinds of
configuration of optical fiber cables: central loose tube, stranded
loose tube, backbones fiber optics, ribbon fiber optics, ADSS, OPGW
etc.(2)Low dispersion , attenuation and PMD enables higher
transmission speeds with more wavelengths over Long-haul Trunks
Communication, CATV and WDM. Product
