The series of multi-core fiber fan-in and fan-out devices are designed and manufactured using a unique process. They have the advantages of low loss, low crosstalk and low loss difference between cores. They perfectly match the multi-core optical fiber developed by our company and are ideal for realizing fiber core multiplexing and solution. Multiplexed key components are widely used in data centers and optical fiber sensing fields. It can provide complete low-loss coupling solutions and customized services for different multi-core optical fibers.
