Optimized Design of 125-μm 6-Core Fiber with Large Effective Area for Wideband Optical Transmission

We propose an optimized design of heterogeneous trench-assisted 125 $-\mu \text{m}$ 6-core fiber with Aeff about 90 $\mu \text{m}^{2}, \lambda_{\text{c}\text{c}}$ about 1300 nm, and XT<-30 dB/100 km for wideband transmission. Relative core multiplicity factor of 6.75 was achieved.
