Application
- Data Center Interconnection (DCI): Connects different data centers within the same city or campus that are approximately 10 kilometers apart, addressing the issue of insufficient optical fibers.
- Metropolitan Area Network (Metro): Used by telecommunications operators for high-speed interconnection between core layer and aggregation layer devices within the metropolitan area.
- 5G Transport Network: Applied in the fronthaul or midhaul scenarios of 5G networks, meeting the requirements of high bandwidth and low latency.
- Enterprise Network Upgrade: Assists large enterprises or campus networks in smoothly upgrading their backbone links from 10G/40G to 100G without altering the existing optical fiber lines.
