Metro & DCI interconnection technology acts as a core link to break geographical boundaries and build cross‑regional computing‑power scheduling networks. Global telecom operators and cloud service providers are accelerating the construction of widely‑covered all‑optical transport networks. Leveraging the high‑speed transmission capability of coherent optical technologies and long‑reach optical transceivers, real‑time synchronization and lossless migration of massive data are realized between data centers across campuses and cities. The technology is widely adopted in high‑value scenarios such as off‑site disaster recovery, remote AI computing‑power scheduling, 5G backhaul aggregation and dedicated financial lines. Market demand for optical‑interconnection solutions featuring large capacity, long transmission reach and flexible scalability is experiencing explosive growth.
