ADVANCED FEATURES:

Twin-Port 800G Connectivity:

The MMS4X00‑NS provides two independent 400G DR4 channels within a single OSFP module, delivering an aggregate bandwidth of 800G. This high-density connectivity reduces the total number of modules required, maximizing switch and server port utilization. It allows network architects to design efficient, scalable fabrics for data centers, AI clusters, and HPC environments, reducing cabling complexity while supporting high-throughput applications.

High-Speed PAM4 Modulation:

Each port employs 100G PAM4 modulation across four lanes per channel, achieving high data density and low error rates. This ensures seamless interoperability with 400G Ethernet DR4 and InfiniBand NDR networks. By leveraging advanced modulation techniques, the MMS4X00‑NS supports latency-sensitive applications such as AI/ML training, scientific simulations, and high-frequency trading, guaranteeing stable performance under peak traffic conditions.

Short-Reach Multimode Support:

Optimized for up to 50 m on OM4 and 30 m on OM3 multimode fiber, the module is ideal for short-reach interconnects in high-density server racks and intra-rack deployments. It ensures low-latency, high-bandwidth communication between servers and switches in HPC clusters, AI workloads, and cloud data centers. The module’s design minimizes signal degradation and maintains optical integrity even in dense fiber environments.

Hot-Pluggable OSFP Form Factor:

Designed for operational flexibility, the MMS4X00‑NS is fully hot-swappable, allowing installation or replacement without powering down host systems. With CMIS 4.0 digital monitoring, administrators can track optical power, voltage, and temperature in real time. This feature enhances predictive maintenance capabilities, reduces downtime, and simplifies large-scale network operations.

Energy-Efficient Operation:

The module supports a low-power mode of 2 W per port when full 400G bandwidth is not needed, optimizing energy consumption. Its efficient thermal design, including finned-top heatsink, ensures stable operation even in high-density 800G racks. This combination of power management and thermal optimization reduces operational costs while maintaining consistent performance for demanding workloads.

Protocol Flexibility:

Fully compatible with 400G Ethernet DR4 and InfiniBand NDR, the MMS4X00‑NS can operate in heterogeneous networking environments. This flexibility makes it suitable for a wide range of deployments, including AI/ML clusters, HPC workloads, cloud infrastructures, and hyperscale data centers, allowing seamless integration with existing network equipment.

Reliable and Safe Design:

The module features Class 1 eye-safe lasers and robust OSFP construction, ensuring compliance with international safety standards. Its durable design guarantees consistent optical performance under demanding conditions, supporting mission-critical applications in data centers, HPC clusters, and AI deployments. The combination of reliability, safety, and operational efficiency makes it an ideal choice for modern high-performance network environments.
