Network transceiver module BlueOptics QDD-400G-SR8-BO, QSFP-DD, 400 Gbps, MPO-16/MTP-16, 100 m

BlueOptics QDD-400G-SR8-BO is a QSFP-DD fiber-optic transceiver module designed for 400 Gigabit Ethernet links. The module supports a maximum data rate of 400 Gbps over multimode fiber using MPO-16 / MTP-16 connectors for short-reach links up to 100 m. The transceiver is housed in a silver metal case and complies with CE, RoHS and FCC regulatory standards. It is supplied as a single unit and is intended for data center interconnects, switch-to-switch links and other high-density 400G interfaces.

Advantages

The module provides 400 Gbps throughput in a QSFP-DD form factor, enabling compact high-density port counts on modern switches and routers. Using MPO-16/MTP-16 multimode fiber connectivity supports parallel optics short-reach deployments up to 100 m. The silver metal housing contributes to mechanical durability and thermal stability. Compliance with CE, RoHS and FCC ensures adherence to common safety and environmental requirements for data center equipment.

How to use

Install the BlueOptics QDD-400G-SR8-BO into a compatible QSFP-DD port on a switch or router that supports 400 Gigabit Ethernet and the QSFP-DD module type. Connect the module to a matching MPO-16 / MTP-16 multimode fiber cable terminated for SR8/parallel optics. Ensure the host device firmware and software recognise third-party transceivers if required by vendor policies. After insertion, verify link status and diagnostics through the host device management interface and confirm the link operates at the expected 400 Gbps rate and within the supported 100 m distance.

Recommendations

Use certified multimode fiber patch cords and proper MPO-16/MTP-16 polarity arrangements to achieve optimal performance. Verify that the switching hardware supports QSFP-DD transceivers and, if available, enable digital diagnostics monitoring (DDM/DOM) in the host to monitor supply voltage, optical power and module temperature for maintenance and troubleshooting.
