40GBASE-SR4 QSFP+ PROGRESS SOFTWARE MPO 150 m

Build compact 40 GbE links without overextending the fiber plant. This 40GBASE-SR4 QSFP+ transceiver is designed for multimode deployments, operating at 850 nm and supporting up to 150 m of reach. The MPO connector format is well suited to parallel optics architectures and high-density data center cabling. For infrastructure teams that need to increase throughput while preserving rack space, SR4 provides a direct path to 40 GbE aggregation and spine connections over multimode fiber. The QSFP+ form factor keeps the module footprint small, while the MPO interface supports structured cabling strategies common in modern switching environments. This module fits short-reach designs where predictable optical performance, dense port utilization, and compatibility with existing multimode infrastructure are essential. It is a practical choice when you need 40 GbE capacity without moving to longer-reach or more complex optical designs.
