HPE P9H29A

(B‑Series) 32 Gb Fibre Channel SFP+ transceiver module (Long‑Wave)

The HPE P9H29A B‑Series SFP+ transceiver is a certified 32 Gb Fibre Channel Long-Wave (LW) module designed for high-speed SAN links. Operating at 1310 nm over single-mode fiber, it supports 32 Gb/s FC speeds and is backward-compatible with 16 Gb and 8 Gb FC ratings. Featuring a duplex LC connector and long-wave DFB laser, the module reliably extends Fibre Channel SAN connections up to 10 km—ideal for inter-site SANs, campus-level storage fabrics, or enterprise edge-to-core SAN links. With built-in Digital Diagnostics Monitoring (DDM/DOM), administrators gain real-time visibility into optical power, temperature, voltage, and other link health metrics. As an HPE OEM-certified module, it delivers guaranteed compatibility with HPE B-series switches, HBAs, and storage platforms.

Features

This Long-Wave transceiver unit supports Fibre Channel speeds up to 28.05 Gbps (32 Gb FC), while also interoperating at 16 Gb and 8 Gb FC rates—providing flexibility during SAN upgrades or mixed-speed fabric deployment . It utilizes a high-quality DFB laser transmitter at 1310 nm and a PIN photodiode receiver, enabling robust optical performance over single-mode fiber up to approximately 10 km depending on fiber attenuation . The module supports industry-standard SFF-8472 diagnostics (DOM/DDM) via I²C interface, offering live readings of link health parameters such as transmit/receive power, temperature, and supply voltage

Advanced Options

As part of HPE B-series transceiver portfolio, the P9H29A is fully qualified and tested to operate with HPE Fibre Channel switches, HBAs, storage arrays (e.g. 3PAR, MSA), and routers. Using genuine modules ensures full support for advanced SAN features such as Port on Demand (PoD), zoning, and Fabric Vision diagnostics—with vendor-backed warranty and firmware compatibility Its plug-and-play design allows automatic recognition by HPE equipment upon insertion, simplifying deployment and ensuring stable operation within enterprise SAN environments. Integration with HPE SANnav or CLI-based switch interfaces is seamless, offering real-time DOM visibility through platforms like GUI dashboards or CLI monitoring. The module’s temperature rating (0 °C to +70 °C), RoHS compliance, and Class 1 laser safety certification further support deployment in controlled data center environments, ensuring reliability over time.
