Time:2026-08-15
A research paper presented at IEEE explores a novel 4-group 2-core fiber with standard 125-μm cladding, achieving low inter-group crosstalk and low intra-group spatial mode dispersion for long-haul applications .
Technical Highlights:
Parameter | Performance |
|---|---|
Fiber Type | 4-group, 2-core |
Cladding Diameter | 125 μm (standard) |
Inter-group Crosstalk | <-40 dB/100km |
Intra-group SMD | 3.67 ps/√km |
Spatial Channels | 8 |
Significance:
Supports space-division multiplexing (SDM) for increased system capacity
Greatly reduces MIMO complexity in long-haul systems
Addresses capacity limits of conventional single-mode fiber
Date of Conference: March 15-19, 2026, Los Angeles, CA
