Standard

• OSFP MSA 5.0 and CMIS 5.1
• IEEE 802.3ck and IEEE 802.3cu

 

Application

• Hyperscale DC: Used for Spine-Leaf or core layer uplink in 400G/800G network architectures.
• AI/High Performance Computing (HPC) clusters: Due to the elimination of the Gearbox chip, its lower latency makes it highly suitable for AI training tasks.
• Metro and campus backbone: Connects different building complexes within a 10km range.
