Mode-division multiplexing (MDM) over 50-km few-mode fiber was achieved using LP01 and LP11 modes. This advance utilized a few-mode EDFA and MIMO equalization for data recovery, paving the way for higher capacity optical networks.

Area of Science:

Optical Communications
Photonics
Fiber Optics

Background:

Mode-division multiplexing (MDM) is a promising technique for increasing optical fiber capacity.
Few-mode fibers (FMFs) support multiple spatial modes, enabling MDM.
Efficient amplification and signal recovery are crucial for practical MDM systems.

Purpose of the Study:

To demonstrate Wavelength Division Multiplexing (WDM) transmission over a 50-km few-mode fiber using multiple spatial modes.
To characterize the performance of a few-mode Erbium-Doped Fiber Amplifier (EDFA) and a few-mode coherent receiver in an MDM system.
To validate the effectiveness of a 6x6 Multiple-Input Multiple-Output (MIMO) equalizer for data recovery in the FMF.

Main Methods:

MDM WDM transmission was implemented over a 50-km FMF link.
