Network transceiver module BlueOptics T-DQ8FNS-N00-M-BO, QSFP-DD, fiber optic, 400000 Mbit/s, MTP/MPO-16, 100 m

BlueOptics T-DQ8FNS-N00-M-BO is a QSFP-DD fiber optic network transceiver module designed for 400G links in data center and aggregation environments. The module supports up to 400000 Mbit/s and uses MTP-16/MPO-16 multi‑fibre connectors for short‑reach multimode fiber links. It comes in a QSFP-DD form factor, is finished in silver colour and is suitable for high‑density racks and switch line cards where QSFP-DD ports are available. The module meets RoHS, FCC and CE requirements and has an estimated MTBF of approximately 1,000,000 hours.

Advantages

The transceiver offers high aggregate throughput of 400G suitable for consolidating multiple 10G/25G/40G/100G channels into a single port, reducing cabling complexity and port count. Use of MTP-16/MPO-16 connectors enables standardized multi‑fiber termination and rapid deployment in ribbon fiber infrastructures. The QSFP-DD form factor provides backward compatibility with dense switch platforms that accept double‑density pluggable optics, while the short 100 m reach on multimode fiber supports common data center topologies.

Key specifications

How to use

Install the QSFP-DD transceiver into a compatible QSFP-DD port according to the host device documentation, ensuring the port is powered down if the vendor recommends hot‑plug precautions. Mate the MTP/MPO‑16 connector to a matching harness or patch panel terminated for MPO-16, taking care to align keys and maintain fiber cleanliness. Verify link status and speed through the network device management interface and perform standard optical link testing to confirm expected throughput and signal quality.

Recommendations

Maintain fiber cleanliness by using appropriate cleaning tools for MPO/MTP ferrules, route multimode patch cords to avoid sharp bends, and ensure the connected multimode fiber meets the required OM grade for 400G short‑reach operation. Confirm host device compatibility with QSFP-DD 400G SR optics before deployment and follow vendor guidance for firmware and cable assemblies.
