FIBER
STANDARDS
The International Telecommunication Union (ITU-T) has
standardized various fiber types for data networks. These are
summarized in the following table.
Table 13: Fiber Standards
ITU-T Standard Description Application
G.651
Multimode Fiber
50/125-micron core
Sho
r
t-reach connections in the 1300- nm
or 850-nm band
G.652
Non-Dispersion-Shifted Fiber
Single-mode, 9/125-micron core
Longer spans and extended reach.
Optimized for operation in the 1310- nm
band. but can also be used in the
1550-nm band
G.652.C
Low Water Peak Non-
Dispersion-Shifted Fiber Single-mode,
9/125-micron core

r
spans and extended reach.
Optimized for wavelength-division
multiplexing (WDM) transmission
across wavelengths from 1285 to
1625 nm. The zero dispersion
wavelength is in the 1310-nm region.
G.653
Dispersion-Shifted Fiber
Single-mode, 9/125-micron core
L

r
spans and extended reach.
Optimized for operation in the region
from 1500 to 1600-nm.
G.654
1550-nm Loss-Minimized Fiber
Single-mode, 9/125-micron core
Extended
long-haul applications.
Optimized for high-power transmission
in the 1500 to 1600-nm region, with low
loss in the 1550-nm band.
G.655
Non-Zero Dispersion-Shifted
Fiber
Single-mode, 9/125-micron core
Extended
long-haul applications.
Optimized for high-power dense
wavelength-division multiplexing
(DWDM) operation in the region from
1500 to 1600-nm.
