Application
- Campus network and edge access for metropolitan area: A transmission distance of 2 kilometers perfectly covers the interconnection between buildings within large campuses as well as the short-distance aggregation scenarios at the edge of the metropolitan area network. It is a cost-effective choice for connecting data centers with external nodes.
- 5G front-haul/backhaul: In 5G networks, it is used to connect the centralized unit (DU) and the distributed unit (CU), meeting the dual requirements of distance and cost for mid-haul scenarios.
- Future-oriented 400G upgrade: FR4 technology is the foundation of the 400G ecosystem. Four 100G FR4 optical signals can be seamlessly aggregated through wavelength division multiplexing technology into a 400G FR4 optical module, protecting your investment.
