This study demonstrates a 73.7 Tb/s mode-division-multiplexed signal transmission over 119 km using few-mode fiber. The experiment achieved a net capacity of 57.6 Tb/s with advanced digital signal processing.

Area of Science:

  • Optical communications
  • Photonics
  • Telecommunications engineering

Background:

  • Mode-division multiplexing (MDM) is a promising technique to increase optical fiber capacity.
  • Few-mode fibers (FMFs) are crucial for supporting multiple spatial modes for MDM.

Purpose of the Study:

  • To demonstrate high-capacity data transmission using mode-division multiplexing over a significant distance.
  • To evaluate the performance of an integrated few-mode fiber transmission system.

Main Methods:

  • Transmission of a 73.7 Tb/s dual-polarization 16-quadrature amplitude modulation (DP-16QAM) signal.
  • Utilized a 119 km few-mode fiber link with an inline multi-mode Erbium-Doped Fiber Amplifier (EDFA).
  • Employed a phase plate-based mode (de-)multiplexer and 6x6 Multiple-Input Multiple-Output (MIMO) digital signal processing.

Main Results:

  • Successfully transmitted a 73.7 Tb/s MDM signal over 119 km of FMF.
  • Achieved a net capacity of 57.6 Tb/s after accounting for overheads (FEC, Ethernet, training).
  • Demonstrated a spectral efficiency of 12 bits/s/Hz.

Conclusions:

  • Mode-division multiplexing in few-mode fibers is a viable technology for ultra-high-capacity optical communication.
  • The developed system shows potential for future terabit-per-second optical networks.
  • Integration of inline amplifiers and advanced signal processing is effective for long-haul MDM transmission.
