Multi-core Fibre Fan-in and Fan-out Module
The multi-core fibre fan-in and fan-out module is used for the high-efficiency coupling of various multi-core fibre cores and several single-mode fibres. It enables channel space division multiplexing and demultiplexing functions in various multi-core fibre applications. This product is manufactured using the tapering process, enabling optical power coupling between multi-core fibres and single-mode fibres with low insertion loss, low crosstalk between fibre cores, and high return loss. The YOFC multi-core fibre fan-in and fan-out module features a seven-channel structure, and can be used to build a complete communication and sensing system alongside YOFC's seven-core fibres with corresponding parameters, demonstrating broad application prospects.
Applications：
Ultra-low crosstalk between fibre cores
Jumper made of FC/PC or FC/APC or bare fibre
Characteristics:
Encapsulation in a metal tube
