Multi‐Linearly Polarized Modal 16 × 10 Gbps MDM System Considering FSO ‐ GIMMF Link Impairments and Atmospheric Losses

ABSTRACT In this work, a quad modal mode division multiplexing system utilizing linearly polarized (LP) modes, namely, LP[0,1], LP[2,2], LP[0,3], and LP[1,3], is designed and analyzed under the impact of free space optics (FSO) and multimode fiber integrated link impairments. Results depict that reliable transmission over 100 m fiber and 100 m FSO links can be achieved at 160 Gbps data rate considering 1–7.5 dB insertion loss, free‐space weather, and turbulence. Also, the spatial shift of 12 μm and spatial tilt of 10° can be supported with low modal crosstalk. Compared to existing works, this work provides long‐reach and high‐speed communication for 5G based networks.
