Multi-core fibre fan-in and fan-out module is a module that has achieved the high-efficiency coupling between multi-core fibre and single-mode fibres while also fulfilling the channel space division multiplexing and demultiplexing function in the application of multi-core fibre.
Special technology and modularized encapsulation are adopted for the optical power coupling between multi-core fibre and single-mode fibres, with low insertion loss, low core crosstalk and high return loss. A complete communication and sensor system can be built using the multi-core fibre fan-in and fan-out module and the multi-core fibres of corresponding parameters, opening up a wide range of application possibilities.
