Keep high-speed switch interconnects stable with the HPE ARUBA 100G QSFP28 MPO SR4 MMF transceiver. Built for 100 GbE short-reach deployments, it uses MPO parallel optics over multimode fiber to support dense leaf-spine architectures and other bandwidth-heavy environments where port efficiency matters. This module is a strong fit when you need 100G throughput without moving to longer-reach, higher-cost optics. The SR4 design is optimized for multimode fiber runs, making it practical for top-of-rack and intra-row links where distance is controlled and cable paths are predictable. MPO connectivity also supports clean parallel fiber deployment in high-density switch environments. For infrastructure teams, the value is in matching the optic to the job: enough reach for short-range data center interconnects, enough density for modern switching platforms, and a form factor built for QSFP28 cages. That balance helps avoid overspending on optics that exceed the requirement while still preserving the performance headroom needed for production traffic.
