Abstract
Transoceanic-class multi-core fibre bidirectional transmission is experimentally demonstrated using step-index profile standard cladding 4-core fibres without trench-assisted pure-silica cores for the first time. 4-SDM/16-WDM channels modulated with 24-Gbaud DP-QPSK are successfully transmitted over 7,000 km with no impact of core-to-core crosstalk.
