BlueOptics QSFP-DD 400G SR8 Glasfaser-Transceiver Q56DD-400G-SR8-BO, 850 nm, MTP/MPO-16, až do 100 m

The BlueOptics QSFP-DD 400G SR8 fiber optic transceiver Q56DD-400G-SR8-BO provides 400 Gbit/s data transmission over multimode fiber using an 850 nm wavelength. Housed in a silver metal QSFP-DD form factor, the module uses an MTP/MPO-16 connector and is designed for short-reach links up to 100 m. The transceiver supports simultaneous transmit and receive channels in the 400GBASE-SR8 specification and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time reporting of optical and electrical parameters. The unit is compliant with CE, FCC and RoHS standards and has an MTBF of 3,000,000 hours.

Advantages

The transceiver delivers high aggregate bandwidth in a compact QSFP-DD form factor while maintaining compatibility with common hardware platforms that support 400GBASE-SR8. Its MTP/MPO-16 interface enables dense multi-channel fiber connections for data center and aggregation environments. Integrated digital diagnostics facilitate remote monitoring of supply voltage, laser current, optical power and temperature, aiding maintenance and troubleshooting. The metal housing and industry-standard component selection contribute to long operational life and stable performance.

Key specifications

How to use

Insert the QSFP-DD transceiver into a compatible QSFP-DD slot of a switch, router or other networking device that supports 400GBASE-SR8. Connect an MTP/MPO-16 multimode fiber patch cable to the module, observing proper polarity and fiber mapping for SR8 operation. Ensure the host system supports DDM/DOM if you intend to monitor diagnostic parameters. Follow the hardware vendor’s procedures for hot-plugging or powering down equipment as required by your installation policies.

Recommendations

For reliable short-reach performance, use OM3 or OM4 multimode fiber rated for 850 nm and verify end-to-end fiber mapping for the MPO-16 interface. Avoid excessive bend radii and maintain clean connector endfaces to minimize insertion loss. When replacing or adding transceivers, confirm firmware and compatibility settings on the host platform and enable DDM/DOM support where available to monitor link health.
