400G QSFP-DD SR4 100m 850nm

The 400GBASE-SR4 QSFP-DD transceiver is engineered for high-capacity, short-reach multimode fiber links in modern data centers. Utilizing a 12-fiber MTP/MPO-12 connector, it transports 400 Gbps by splitting the signal into four parallel 100 Gbps lanes over OM4 fiber (up to 100 m) or OM3 fiber (up to 70 m). Compliant with IEEE 802.3bs and the 400GAUI-8 electrical interface, this module also supports breakout configurations of 2 × 200G-SR or 4 × 100G-SR, offering maximum deployment flexibility.

Parallel Lane Architecture
Four independent 100 Gbps channels, each on a dedicated wavelength, ensure aggregate throughput of 400 Gbps.

MTP/MPO-12 Interface
Standardized female MPO-12 port simplifies cabling and polarity management for Type A straight-through connections.

Optimized for OM4 Multimode
• Reach: 100 m on OM4; 70 m on OM3 at 850 nm.
• Ideal for 400GbE leaf-spine and top-of-rack interconnects.

Standards Compliance
Meets IEEE 802.3bs, 400GAUI-8, QSFP-DD MSA, and SFF-8665 specifications for seamless interoperability.

Digital Diagnostics
On-board I²C monitoring provides real-time feedback on optical power, temperature, voltage, and bias current.

Hot-Swap Capability
QSFP-DD form factor allows live insertion and removal without service interruption.
