Group delay statistics and management in mode-division multiplexing

2015 49th Asilomar Conference on Signals, Systems and Computers, 2015
Reduction of the group delay (GD) spread is crucial for minimizing multi-input multi-output (MIMO) signal processing complexity in mode-division multiplexing (MDM) systems using multi-mode fibers (MMFs). In this paper, we focus on GD statistics and management techniques.

Design of Hollow Optical Fiber for Mode Division Multiplexing

2018 20th International Conference on Transparent Optical Networks (ICTON), 2018
A study is presented of the hollow optical fiber (HOF) properties needed to achieve 10-mode multiplexing transmission. A combination of mode division multiplexing (MDM) processing with optical LP mode separation is proposed to prevent the need for MDM computation. The impact of modal properties as chromatic dispersion and the differential mode delay of

Adaptive MIMO Signal Processing for Mode-division Multiplexing

Optical Fiber Communication Conference, 2012
The fiber-optic multiple-input multiple-output (MIMO) channel is analyzed. For a 6×6 MIMO experiment over 96 km few-mode fiber it is found that the mode dependent loss is 3 dB, with negligible temporal fluctuations and almost no impact on capacity.
