Description
Application
G.651
Multimode Fiber
50/125-micron core
Short-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
Longer 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
Longer 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.
