Question

Accepted Answer

An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal.

Types of optical amplifiers include erbium-doped fiber amplifiers (EDFAs), semiconductor optical amplifiers (SOAs), and Raman amplifiers.
Mux and demux are devices used in wavelength-division multiplexing (WDM) systems to combine and separate multiple optical signals on a single fiber.
DWDM (Dense Wavelength Division Multiplexing) is a technology that multiplexes multiple optical signals on a single fiber by using different wavelengths of light.
Basic components of DWDM include optical transmitters, optical receivers, optical amplifiers, and multiplexers/demultiplexers.
Attenuation refers to the loss of signal strength as it travels through a fiber optic cable, while dispersion loss refers to the spreading of the signal over time.
CRC (Cyclic Redundancy Check) is a method used to detect errors in transmitted data by adding a fixed-length check value to the data.
OSC (Optical Supervisory Channel) is a separate channel used in DWDM systems for management and control purposes.
Receiver sensitivity in a fiber optics link can be found by measuring the minimum optical power required for the receiver to detect a signal.
