Network transceiver module BlueOptics QDD-400G-SR8-S-BO, 400000 Mbit/s, QSFP-DD, MPO-16/MTP-16, 100 m

BlueOptics QDD-400G-SR8-S-BO is a QSFP-DD fiber optic transceiver module designed for 400 Gbit/s multimode short-range links. The module implements the 400GBASE-SR8 SR8 topology using an MPO-16 / MTP-16 connector and operates with 850 nm optical transmit and receive channels. The QSFP-DD form factor supports high-density port deployments in data center switching, aggregation, and storage interconnects. The transceiver supports link distances up to 100 m over appropriate multimode fiber and has an MTBF rating of 3,000,000 hours for long-term availability.

Advantages

The transceiver follows MSA-compliant QSFP-DD mechanical and electrical specifications and is compatible with common hardware platforms that accept 400GBASE-SR8 QSFP-DD modules. It integrates digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser current, optical transmit/receive power and temperature. The MPO-16/MTP-16 interface enables eight-lane multimode operation (SR8) for dense parallel optics, and the product is produced using industry-grade optical components to ensure consistent performance and extended service life.

How to use

Install the module into a compatible QSFP-DD port in accordance with the host equipment vendor guidelines and ensure that the device firmware supports third-party 400GBASE-SR8 modules if required. Connect an MPO-16/MTP-16 multimode patch cable that matches the transceiver pinout and the fiber type (OM3/OM4 recommended for 100 m links). Verify the optical link and monitor status using the host system and the module's DDM/DOM readouts to confirm correct power levels and temperature before placing the link into production.

Recommendations

Use OM3 or OM4 multimode fiber for optimal performance at 400 Gbit/s and distances up to 100 m. Keep MPO/MTP connectors clean and use appropriate polishing caps or dust covers during installation. Confirm that the host hardware and management software support the QSFP-DD SR8 profile and DDM/DOM functionality for full monitoring capability.
