MCF-enabled Ultra-High-Density 256-core MT Connector and 96-core Physical-Contact MPO Connector

Ultra-high-density multi-MCF connectors were realized with the insertion loss of <1 dB by 125-μm-dadding single-mode 8-core fibers and a newly developed simple rotational alignment method using MT-insertable V-groove array with the MT-standard 250-μm fiber pitch.
