Typical Applications ✨ 25GBASE-LR Backbone Links & Long-Reach Interconnect
Engineered for long-distance backbone restructuring across campuses or buildings. Delivers lossless, low-latency data links up to 10 km (6.2 miles) over standard Single-Mode Fiber (SMF, G.652), breaking through short-reach multi-mode limitations.
✨ 5G Fronthaul & Midhaul Networks (eCPRI Carrier)
Perfecting 25G high-speed, ultra-low latency pipelines required by the eCPRI protocol between 5G base stations (AAU) and Distributed Units (DU), serving as a core component in next-gen carrier-grade 5G wireless infrastructures.
✨ Hyper-Scale Data Center Interconnect (DCI)
Optimizes high-capacity, high-density data pipelines inside modern data centers. Primarily configured for Spine-to-Leaf core distribution links, providing 2.5x the throughput of legacy 10G topologies within an identical physical footprint.
✨ Enterprise Core / Aggregation Switch Uplinks
Provides agile, high-speed uplink aggregation for enterprise networks. Offers native compatibility with Huawei CloudEngine series switches and high-end core routers, significantly expanding the cloud perimeter bandwidth of corporate infrastructures.
✨ High-Performance Server & Storage Area Network (SAN) Expansion
Bridges high-bandwidth server NICs with next-generation all-flash storage arrays (SAN). Delivers high-density, hot-swappable optical port density to completely eliminate I/O bottlenecks in cloud computing clusters and heavy computational workloads.
