Infiniband NDR Technology Explained

Infiniband NDR (Next Data Rate) is the latest iteration in the evolution of the Infiniband interconnect standard. It is engineered for extremely high-bandwidth, low-latency data transfer, making it a favorite among HPC architects and hyperscale data centers. The 400Gbps data rate of NDR doubles the throughput of previous HDR generation transceivers, enabling breakthrough performance for demanding workloads.

Advantages of NDR over HDR and EDR

• Double the bandwidth of HDR connections
• Lower latency and jitter under high loads
• Enhanced signal integrity across long distances
• Support for larger HPC node clusters
• Lower operational cost per bit

OSFP Interface and Multimode Compatibility

The OSFP form factor is designed to provide scalability and thermal efficiency for high-speed transceivers. The P49386-001 utilizes the OSFP interface to ensure optimal signal transmission and minimal electromagnetic interference, even when deployed in high-density server racks.

OSFP for 400G

Unlike earlier SFP or QSFP modules, OSFP is specifically engineered to support 400G and beyond. Its larger size allows for superior heat dissipation, making it ideal for continuous operation under high-load conditions.

Multimode Fiber Benefits

• Cost-effective deployment over short to medium distances
• Ease of installation and maintenance
• Lower attenuation compared to single-mode for <50M runs

Supported Multimode Standards

The transceiver supports various OM standards including OM3, OM4, and OM5 fibers, enabling flexibility depending on existing infrastructure and future upgrade plans.
