We optimized and fabricated an ultra-bend-resistant 4-core simplex cable (SXC) employing 4-core multicore fiber (MCF) suitable for short-reach dense spatial division multiplexing (DSDM) optical transmission in the O-band. The characteristics of transmission loss. macro-bending and cross-talk (XT) between adjacent cores after cabling were firstly clarified. By introducing the trapezoid... https://stilleners.shop/product-category/fender-vent/
