BlueOptics BO25K859S2D transceptor QSFP+ 40GBASE-SR4, MPO/MTP, fibra multimodo, 4x850nm, 150m, 0-70°C MMA1B00-B030D-BO

40 Gbps over multimode fiber with a 150 m reach — the BlueOptics BO25K859S2D QSFP+ transceiver delivers high-density 40GBASE-SR4 connectivity for data centers and enterprise networks. It is fully compatible with NVIDIA MMA1B00-B030D and uses a single MPO/MTP connector for all four parallel lanes.

Overview

This QSFP+ module operates at 4x 850 nm using VCSEL lasers, meeting the 40GBASE-SR4 standard. It supports hot-plug insertion and digital diagnostics monitoring (DDM) for real-time link health. The transceiver is MSA compliant and draws less than 1.5 W, making it suitable for high-density port configurations.

What stands out

• 40 Gbps aggregate data rate over 4 parallel 10 Gbps lanes
• MPO/MTP connector for simple multimode fiber cabling
• 150 m reach on OM4 multimode fiber
• Operates from 0°C to +70°C
• Hot-pluggable and DDM-enabled
