Optical fiber devices made using wavelength division multiplexing (WDM) technology are called wavelength division multiplexers. What is Wavelength Division Multiplexing (WDM) technology, the principle is actually very simple. In the field of optical fiber communications, wavelength division multiplexers play a very important role and play an important role.

In the field of optical fiber communications, wavelength division multiplexers play a very important role and play an important role. Optical fiber devices made using wavelength division multiplexing (WDM) technology are called wavelength division multiplexers. What is Wavelength Division Multiplexing (WDM) technology, the principle is actually very simple.

Principle of Wavelength Division Multiplexing (WDM): Transmitter: Combining two or more optical carrier signals of different wavelengths at the transmit end through multiplexers (also known as Multiplexers) and coupling them to optical lines. The transmission technology of the same optical fiber; the receiving end: the demultiplexer (also known as demultiplexer) separates the optical carriers of various wavelengths, and then performs further processing by the optical receiver. To restore the original signal.

Summary: This technique of transmitting two or more different wavelength optical signals simultaneously in the same fiber is called wavelength division multiplexing.


Previous: Utilize the transmission performance that can be achieved

Next: Independent of signal rate and electrical modulation
