Move 100 GbE traffic across short-reach optical links with a QSFP28 SR4 transceiver built for MPO-based infrastructure. This module is suited to data center fabrics and high-density switching environments where bandwidth, port efficiency, and standardized optical cabling are essential. The SR4 design is intended for short-distance multimode deployments, making it a strong fit for top-of-rack to aggregation links, leaf-spine architectures, and other intra-rack or row-level connections. With a 100 m reach, it supports common short-run optical designs without the overhead of longer-reach optics. For teams managing procurement and spares, the value is straightforward: a focused 100 GbE module that aligns with dense switch layouts and established MPO cabling practices. It helps keep port planning clean, reduces complexity in short-reach deployments, and supports the kind of throughput modern infrastructure demands from a premium optical component.
