Optical networks are high-capacity telecommunications networks that use optical technologies and components to route, groom, and restore traffic at the wavelength level. They provide wavelength-based services and use fiber optic cables that can carry more information over longer distances than electrical or wireless signals. Optical networks are driven by increasing fiber capacity needs, restoration capabilities, cost reductions, and wavelength services. The main types are active and passive optical networks, and they are used in long haul, metro, and business access applications.

3. Optical networks are high-capacity
telecommunications networks based
an optical technologies and
component that provide routing,
grooming , and restoration at the
wavelength level as well wavelength
based services.

4. Fiber optic communications is based
on the principle that the light in a glass
medium can carry more information
over distances than electrical signals
can carry in a copper coaxial medium
or radio frequencies through a wireless
medium.
