Explain in brief DWDM signal flow ?

Question

Accepted Answer

DWDM signal flow involves transmitting data over multiple wavelengths of light through optical fibers.

DWDM signal flow starts with data being converted into electrical signals.
The electrical signals are then converted into optical signals using a transmitter.
The optical signals are then multiplexed together, combining multiple wavelengths onto a single fiber.
The multiplexed signals are transmitted over long distances through optical fibers.
At the receiving end, the signals are demultiplexed to separate the wavelengths.
The demultiplexed signals are then converted back into electrical signals using a receiver.
Finally, the electrical signals are processed to retrieve the original data.
