Question
Answer
What is optical
communication and why is
it important in modern
networks?
Optical communication refers to the transmission of
information using light signals through optical fibers. It is
important because it offers high bandwidth, low signal
attenuation, and immunity to electromagnetic
interference, making it ideal for high-speed and long-
distance data transmission in modern networks.
What are the key
components of an optical
communication system?
The key components include a transmitter (laser diode or
LED), optical fiber as the transmission medium, optical
amplifiers or repeaters, and a receiver (photodiode) to
detect the light signals.
Explain the difference
between single-mode and
multi-mode optical fibers.
Single-mode fibers have a small core diameter (about 9
microns) and allow only one mode of light to propagate,
enabling longer transmission distances with higher
bandwidth. Multi-mode fibers have a larger core diameter
(about 50 or 62.5 microns) and support multiple
propagation modes, suitable for shorter distances due to
modal dispersion.
What are the common
sources of attenuation in
optical fibers?
Common sources include absorption (due to impurities in
the fiber), scattering (Rayleigh scattering caused by
microscopic variations), bending losses (macrobending
and microbending), and connector or splice losses.
How does Wavelength
Division Multiplexing
(WDM) enhance optical
network capacity?
WDM allows multiple optical carrier signals at different
wavelengths to be multiplexed and transmitted
simultaneously over a single optical fiber, significantly
increasing the total data capacity without needing
additional fibers.
What are optical amplifiers
and what role do they play
in optical networks?
Optical amplifiers, such as Erbium-Doped Fiber Amplifiers
(EDFAs), amplify optical signals directly without converting
them to electrical signals. They are crucial for extending
the transmission distance by boosting signal strength and
enabling long-haul communication.
