With the advent of 5G, the demand for high-speed, high-density fiber transmission is becoming more and more urgent. It will become inevitable to expand one-dimensional fiber array into 2D fiber array (2D Fiber Array, fiber surface array, 2D fiber array).
The 2D fiber array is coupled with the laser, and the multi-channel laser can be arranged inten-sively and miniaturized through the 2D fiber array to realize laser face array transmission.The fiber optic array is coupled to the detector to achieve the requirement of replacing expensive area array detectors or splicing into large area array detectors with small array detectors.
This 2D fiber array allows thousands of laser channels to position precisely in the X direction and Y direction simultaneously without any crosstalk. Array coupling, switching from 1D to 2D, and signal transmitting and receiving can be easily achieved.
