BlueOptics QSFP-DD transceiver DDQ+85MP01D-BO, MPO-16/MTP-16, 400GBASE-SR8, multimode 850nm, 100m, DDM/DOM, 0–70°C

BlueOptics QSFP-DD Transceiver DDQ+85MP01D-BO is a compact, hot-pluggable optical module designed for 400G short-reach multimode links. The transceiver operates at 850 nm and uses an MPO-16 / MTP-16 interface to support 400GBASE-SR8 transmission at distances up to 100 meters over compatible multimode fiber. It includes digital diagnostic monitoring (DDM/DOM) for real-time parameter reporting and is specified for operation in ambient temperatures from 0 °C to 70 °C, making it suitable for data center aggregation and switch-to-switch interconnects.

Advantages

This QSFP-DD transceiver offers a high-density 400G solution in a compact form factor, enabling efficient use of port capacity in modern network racks. The MPO-16/MTP-16 connector and SR8 modality allow parallel multimode transmission with predictable reach up to 100 m, while integrated DDM/DOM provides live monitoring of optical parameters to assist with maintenance and troubleshooting. Rated for 0–70 °C operation, the module supports deployment in standard data center environments without additional cooling requirements.

Key specifications

How to use

Install the QSFP-DD transceiver into a compatible QSFP-DD port on a switch or router while following the host device manufacturer’s hot-plug procedures. Connect an MPO-16/MTP-16 multimode fiber trunk to the module, ensuring correct polarity and that the fiber type and link length meet the 400GBASE-SR8 requirements. Monitor DDM/DOM parameters through the host system to verify optical power, temperature, and other diagnostics during commissioning and operation.

Recommendations

Use this transceiver with verified multimode cabling (OM3/OM4 or higher as recommended by system requirements) and MPO-16/MTP-16 assemblies that maintain proper polarity and insertion loss. Verify compatibility with the switch vendor and enable DDM/DOM monitoring to detect degraded links early. For distances near the 100 m limit, validate end-to-end optical loss budgets and consider cable quality, connector cleanliness, and patch panel transitions to ensure reliable 400G links.
