AFBR-79EBPZ-BO BlueOptics BO25K856S2D Transceiver

High-Density 40GbE QSFP SR Multimode Optical Transceiver for Data Centre Switching with the AFBR-79EBPZ-BO

The AFBR-79EBPZ-BO is a 40GbE Ethernet QSFP SR optical transceiver designed for short-reach, high-port-density switching fabrics where deterministic latency and clean link budgets are required. In leaf/spine architectures, the AFBR-79EBPZ-BO supports rapid uplink provisioning over multimode fiber, enabling predictable east-west bandwidth without the complexity of long-reach optics.

Optimised for modern switch and NIC platforms, the AFBR-79EBPZ-BO integrates cleanly into 40GbE QSFP cages and aligns with PCIe-based compute and storage nodes that depend on consistent network throughput. Its SR multimode profile targets up to 100m reach, supporting high-availability topologies and maintenance windows by allowing fast module swaps and standardized patching. The LC duplex interface simplifies structured cabling in dense racks, while the 918nm wavelength ensures stable operation in MMF environments commonly used for short interconnects in cluster and storage networks.

Why Choose the AFBR-79EBPZ-BO?

The AFBR-79EBPZ-BO provides a balanced density-to-performance ratio for 40GbE refresh cycles, delivering an enterprise-grade SR link option that scales across repeatable switch-to-switch and switch-to-server patterns. By standardising on the AFBR-79EBPZ-BO, IT teams reduce interoperability risk in Ethernet fabrics, keep sparing strategies simple, and maintain consistent operational behavior across ports and line cards.

BlueOptics focuses on pragmatic engineering for data centre deployments, combining compliance-driven design with production consistency to support long-lived platforms. With CE, FCC, and RoHS alignment, BlueOptics modules are suited for regulated environments and structured change control processes.
