Detailed Specifications

HPE  R9B41A 400G QSFP‑DD MPO‑16 SR8 Transceiver

Overview

The HPE R9B41A is a single‑port QSFP‑DD form‑factor transceiver designed for ultra‑high‑bandwidth server‑ and switch‑fabric uplinks inside the data centre. It provides a 400 Gb/s line rate via an SR8 architecture over multimode fibre, making it suitable for short‑reach (up to 100 m on OM4/OM5 MMF) connections between high‑density switching fabrics, aggregation tiers or compute clusters. Engineers can use this module to collapse multiple lower‑speed links into one compact high‑speed link, simplify cabling and conserve line‑card slot space in network chassis. It integrates with modern HPE/Aruba networking platforms that support QSFP‑DD ports and ensures compatibility with the vendor’s fabric‑ready infrastructure.

Key Features

  • Single‑port QSFP‑DD supporting 400 Gb/s throughput

  • MPO‑16 connector for high fibre‑density short‑reach links

  • Short‑reach SR8 optics: up to 100 m on OM4/OM5 multimode fibre

  • Digital Optical Monitoring (DOM) support for link‑health visibility
