1D and 2D Fiber Array
Fibers can be arranged in what are called one-dimensional (1D) and two dimensional (2D) arrays.
A 1D array is a single line of fibers, and a 2D array is a grid of fibers in both X and Y dimensions. In both cases, they are specified by the spacing between fibers. In the case of 1D array, there is a single defining dimension denoting the center-to-center position of the cores of the fibers.
For 2D arrays, there are two dimensions, X and Y, that define the core positions. One-dimensional arrays can be manufactured by several different techniques. The manufacturing technique will define the position accuracy of the fiber cores.
Below mind-map shows most of the option that you can make with a FOA.
Or you can send us a drawing directly, we will finalize your design.

No optical crosstalk among each channel. 2D Fiber Array can be coupling to Micro Lens Array as well. Which can realized collimating and focus function. Make it easier for receiving and transmitting signals.

Usually we will choose the optimal fabrication based on your requirement.
V-Grooves Stacking:Make V-Groove on a Flat Wafer, and insert the fibers into V-Groove. Using optical adhesive for solidating. This will be one layer of the V-Grooves. With a position & alignment device, we can stack more layers together. |

Channel Packing:We pack fiber closely in a flat slot. This method is highly scalable. But fiber pitch is not adjustable. (Since they are all packed together) |

Bundling:Pack fiber in a premade bundle. |
