Sustain 400 GbE throughput across short-reach multimode infrastructure with an OSFP transceiver built for dense NVIDIA environments. The 400GBASE-SR4 design is suited to high-bandwidth switch-to-switch and switch-to-server links where low-latency optical transport and efficient rack utilization are essential. This module fits deployment models that demand fast uplinks without the cost and complexity of longer-reach optics. Its OSFP form factor supports modern high-port-count platforms, helping infrastructure teams preserve faceplate density while scaling aggregate bandwidth. For environments standardizing on multimode fiber, SR4 optics provide a practical path for short-distance aggregation inside the data hall. Axiom positions this module for teams that need dependable optics aligned to enterprise switching requirements. It is a strong fit for refresh projects, leaf-spine builds, and capacity expansions where the transceiver choice affects both performance and operating cost. When the network design calls for 400 GbE over short distances, this module delivers the right balance of speed, density, and deployment simplicity.
