Modulo ricetrasmettitore di rete BlueOptics QSFPDD-400G-SR8-MM850-BO, QSFP-DD 400 Gbit/s, 850 nm, multimodale, 100 m

BlueOptics QSFPDD-400G-SR8-MM850-BO is a QSFP‑DD fibre optic transceiver module designed for short-reach multimode links. It supports a 400 Gbit/s aggregate data rate over multimode fibre at an operating wavelength of 850 nm, with a maximum reach of up to 100 m. The module uses a QSFP‑DD connector, comes in a metal silver housing and has a compact form factor and low weight, making it suitable for high-density switch and data centre environments where short-reach, high-bandwidth links are required.

Advantages

This QSFP‑DD module provides a high aggregate throughput of 400 Gbit/s in a single pluggable form factor, enabling consolidation of multiple lanes into a single port. The use of 850 nm multimode optics offers reliable short-distance transmission up to 100 m while keeping power and thermal demands low with a 3.3 V supply. Its metal silver housing ensures mechanical robustness and electromagnetic shielding for rack-mounted and modular switch platforms.

Key specifications

How to use

Insert the QSFP‑DD transceiver into a compatible QSFP‑DD port on a switch, router or host adapter following the equipment manufacturer’s hot‑plug instructions. Ensure the multimode fibre patch cables are compatible with 850 nm optics and that connector polishing and cleaning procedures are observed before mating. Verify link status and negotiate speed using the device management interface; monitor signal integrity and temperature during initial operation to confirm stable performance.

Recommendations

Use certified multimode fibre (OM3/OM4 or as specified by your network design) and maintain proper fibre handling and cleaning practices. Match transceiver and cable specifications to the intended reach (up to 100 m) and ensure compatible QSFP‑DD host firmware for optimal interoperability and link stability.
