980-9I055-00H000 Mellanox Transceiver

High-Density 200Gb/s InfiniBand QSFP56 FR Optical Transceiver with the 980-9I055-00H000

The 980-9I055-00H000 is a Mellanox QSFP56 optical transceiver engineered for 200Gb/s InfiniBand fabrics, delivering deterministic throughput and low latency for HPC clusters and AI training interconnects. Designed around a QSFP56 electrical interface and CMIS 4.0 management, it integrates cleanly with modern GPU and CPU platforms by sustaining high port density without compromising telemetry, operability, or link stability.

As an FR singlemode module operating at 1310nm, the 980-9I055-00H000 supports up to 2km reach over OS2 fibre using an LC duplex connector, making it well-suited to leaf-spine architectures, end-of-row aggregation, and controlled data centre interconnect within campus-scale environments. The 5.5W module TDP aligns with dense switch line cards where airflow and thermal headroom are critical, while standards compliance (IEEE 802.3bs, SFF-8665, MSA, RoHS) supports predictable integration across qualified switch and adapter ecosystems.

Why Choose the 980-9I055-00H000?

The 980-9I055-00H000 provides a balanced density-to-performance profile for 200G InfiniBand deployments, enabling scalable fabric growth with consistent optical budgets and operational consistency.
