Introduction

High-density optical interconnects are a significant trend in high-capacity, low-latency communication networks. As a typical product of high-density optical interconnect technology, optical circuit boards are based on an integrated structure of optical fiber or optical waveguide, which carries optical devices and enables optical interconnection between optical devices or systems, is crucial for supercomputing.

This provides a new board-level optical interconnect solution for fields such as computers, data centers, and broadband communications. The GB/T 46385 series of standards aims to standardize optical...
