BlueOptics BO25K859S2D QSFP+ 40GBASE-SR4 Transceiver, MPO/MTP, Multimode Fiber, 4x850nm, 150m, 0°C to +70°C, IBM 78P6916 Compatible 78P6916-BO

QSFP+ transceiver for 40 Gigabit Ethernet over multimode fiber, delivering 40 Gbps throughput across four 10 Gbps channels at 850 nm. The MPO/MTP interface supports short-reach links up to 150 meters on OM4 multimode fiber, making it suitable for high-density data center interconnects and enterprise backbone aggregation.

Advantages

Hot-pluggable QSFP+ form factor allows installation without interrupting network operation. Digital Diagnostics Monitoring (DDM) provides real-time visibility into transmit/receive power, temperature, and laser bias current. VCSEL-based optics ensure reliable performance across the 0°C to +70°C operating range.

Suitable for

• 40GBASE-SR4 Ethernet links in data centers
• Short-reach connections between switches, routers, and servers
• High-density aggregation where MPO/MTP cabling is deployed
