Detailed Specifications

HPE P49762-B21

2×400 Gb Ethernet/InfiniBand OSFP Multi-Transceiver module

The HPE P49762-B21 is a cutting-edge OSFP (Octal Small Form Factor Pluggable) transceiver designed for high-density backbone and switch-side connectivity in InfiniBand NDR and Ethernet 800 Gb environments. Delivering two independent 400 Gb/s channels, it achieves 800 Gb aggregate bandwidth over multimode fiber across up to 50 m. Featuring a dual MPO-12/APC optical interface and density-optimized OSFP packaging, this hot-pluggable module supports HPE high-speed fabric needs while ensuring minimal downtime during maintenance. 

Features

The P49762-B21 adheres to InfiniBand NDR and 400GBase-X Ethernet standards, incorporating eight 100 Gb PAM4 lanes (4 channels per 400 Gb path) for reliable, full-duplex transmission. Its OSFP form factor supports dense high-performance switch and server interconnects with an MPO-12/APC connector, designed for industrial-grade data center architectures. Operationally, the module provides a maximum reach of 50 m on OM4 multimode fiber and approximately 30 m on OM3 fiber, powered by efficient 17 W typical consumption and a low-power standby of about 1.5 W.  Compatible with QSFP-DD models, it supports hot-swap deployment for uninterrupted network operations. Compliance with OSFP MSA, CMIS 4.0, RoHS, and class 1 laser safety standards ensures robust performance and safety certification. 

Advanced Options

The P49762-B21 is built for ultra-high-speed, low-latency networking—ideal for HPC, AI clusters, or large-scale data center fabric backbones. Its dual 400 Gb architecture provides immense throughput while enabling network architects to simplify cabling via MPO connectors.With support for InfiniBand NDR and Ethernet standards, this module enhances infrastructure agility and scalability. Robust power management (a 17 W active footprint) and compliance with OSFP/CMIS standards ensure both energy efficiency and seamless deployment. The hot-swappable design supports in-service maintenance—vital for minimizing downtime in critical operations.
