| Material
Dispersion |
Pulse
dispersion due to the variations in a material's
refractive index as a function of wavelength. |
| Macrobending |
In
an optical fiber, all macroscopic deviations of
the fiber's axis from a straight line; distinguished
from microbending. |
| MAN
(Metropolitan Area Network) |
A network
covering an area larger than a local area network.
A wide area network that covers a metropolitan area.
Usually, an interconnection of two or more local
area networks. |
| Material
Dispersion |
Dispersion
resulting from the different velocities of each
wavelength in a material. |
| Mechanical
Splice |
An
optical fiber splice accomplished by fixtures or
materials, rather than by thermal fusion. |
| Microbending |
Minute
but severe bends in fiber that result in light displacement
and increased loss. Most microbending can be avoided
by the correct selection of materials and proper
cabling, handling, and installation techniques |
| Mode |
A single
electromagnetic wave traveling in a fiber. |
| Mode
Coupling |
The
transfer of energy between modes. In a fiber, mode
coupling occurs until equilibrium mode distribution
(EMD) is reached. |
| Mode
Evolution |
The
dynamic process a multilongitudinal mode laser undergoes
whereby the changing distribution of power among
the modes creates a continuously changing envelope
of the laser's spectrum. |
| Mode |
A path
of light through a fiber. |
| Multimode
Dispersion |
Dispersion
resulting from the different transit lengths of
different propagating modes in a multimode optical
fiber. Also called modal dispersion. |
| Multimode
(MM) Fiber |
An
optical fiber that has a core large enough to propagate
more than one mode of light The typical diameter
is 62.5 micrometers. |
