AI Technical Summary
Traditional fiber optic arrays suffer from low density, insufficient precision, and poor stability, making it difficult to meet the demands of high-speed, low-latency, and high-bandwidth communication.
The substrate employs a through-hole array and a strip hole array structure. The through-hole array contains polygonal or circular holes to accommodate optical fibers, while the strip hole array contains positioning grooves to increase the stability of the optical fibers. The positioning accuracy and stability of the optical fibers are improved by dispensing and curing.
It achieves high alignment accuracy and stability of high-density fiber optic arrays, reduces device size, and meets the requirements of high-speed communication.
