40G-QSFP-SR4-1-BO
High-Density QSFP 40GbE SR4 Multimode Optical Transceiver for Data Centre Interconnects with the 40G-QSFP-SR4-1-BO
The 40G-QSFP-SR4-1-BO is a QSFP 40GBASE-SR4 transceiver engineered for short-reach, high-port-count Ethernet fabrics where predictable latency and clean optical budgets are required. In leaf/spine and top-of-rack designs, the parallel-optics MPO interface consolidates multiple lanes into a compact module to maintain switch front-panel density while simplifying structured cabling for 40GbE aggregation.
Designed for multimode fiber at 850nm, the 40G-QSFP-SR4-1-BO supports up to 150m reach, aligning with intra-row and adjacent-rack interconnects in modern data halls. The module integrates seamlessly into QSFP 40GbE ports, enabling consistent link behavior across switch generations and helping architects scale east-west bandwidth without consuming additional PCIe resources or server expansion slots. This optical approach preserves server I/O lanes for storage and accelerator traffic while keeping the network layer deterministic for virtualization, HPC clusters, and AI data pipelines.
Why Choose the 40G-QSFP-SR4-1-BO?
The 40G-QSFP-SR4-1-BO provides a practical density-to-throughput profile for 40GbE Ethernet over MMF, minimizing rack-level complexity through a single MPO/MTP connection per link. It is suited to standardized data centre deployments where repeatable patching, controlled reach, and reliable optics are essential for scalable leaf/spine uplinks and switch-to-switch interconnects.
BlueOptics focuses on interoperability-driven engineering for enterprise networks, with transceivers designed to meet data centre operational requirements around consistency, signal integrity, and lifecycle stability. This aligns the optics layer with modern structured cabling standards and change-controlled infrastructure processes.
Key Applications:
- Top-of-rack to leaf/spine switch uplinks
- 40GbE switch-to-switch interconnects
- High-density 40GbE Ethernet aggregation
- Data centre MMF backbone links
