400G QSFP-DD

400G QSFP-DD

400G QSFP-DD transceivers are addressing the technical challenges of achieving high speed 400G interconnections. The transceivers have four optical lanes that operate at 100Gbps PAM4 modulation, providing solutions up to 400 Gbps. The transceivers have on the electrical side 8 lanes of 53.125Gbps PAM4. They are compliant with the QSFP-DD MSA (DD = Double Density). Digital diagnostics functions are available via the I2C interface, as specified by CMIS (Common Management Interface Specification).

Key Features & Technical Advantages

High-Speed PAM4 Interface: Features an 8×53.125 Gbps PAM4 electrical modulation to support high-capacity bandwidth up to 425 Gbps.
QSFP-DD MSA Compliant: Guarantees standard compatibility and smooth integration with industry-leading network switches and routers.
Low Power Consumption: Optimized thermal design ensures highly efficient operations with power dissipation under 10W (< 10W).
Integrated Digital Diagnostic Monitoring (DDM): Built-in DDM functionality accessible via an I2C interface allows real-time tracking of critical performance parameters (temperature, voltage, optical power).
Flexible Connectivity: Available with Duplex LC and MPO connectors to support both single-mode and multi-mode fiber cabling.
Eco-Friendly & Reliable: Fully RoHS & REACH compliant with a standard single 3.3V power supply and a commercial case operating temperature range of 0°C to 70°C.

Target Applications

High-Density 400G Ethernet: Ideal for high-bandwidth core networks and spine-leaf architectures.
Next-Gen Data Centers: Built for hyperscale data centers, cloud computing hubs, and high-performance computing (HPC) environments.
Enterprise Telecom Backbones: Optimizes bandwidth for massive data transport and low-latency storage area networks (SAN).
