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

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.
