HPE P9H32A

B-Series 32 Gb Fibre Channel Short‑Wave (SW) SFP28 Transceiver Module

The HPE P9H32A is a high-performance 32 Gb Fibre Channel short-wave transceiver designed for HPE B-Series SAN switches and enterprise storage environments. Operating at 850 nm wavelength, this SFP28 module enables data transfer rates up to 28.05 Gbps and is fully backward compatible with 16 Gb and 8 Gb Fibre Channel. With support for multimode fiber (OM4 up to 100 m, or ~70 m OM3), it delivers low-latency, high-integrity optical connectivity for mission-critical backend applications. Plug-and-play with HPE SN6600B and SN8600B Fibre Channel platforms, this module includes digital diagnostics monitoring (DDM/DOM) for real-time optical link health insights, making it ideal for SAN uplinks, server fabric interconnects, or dense storage deployments.

Features

Built for enterprise reliability, the P9H32A module utilizes VCSEL laser transmission and PIN photodiode reception. It conforms to industry standards such as FC‑PI‑6, SFF‑8431/8432, SFF‑8472, and SFP MSA, ensuring seamless compatibility across Fibre Channel fabrics and HPE SAN infrastructures With optical diagnostic capabilities, administrators can monitor link parameters including TX/RX power, temperature, and voltage in real time, facilitating proactive maintenance.

Advanced Options

With a typical power draw of ~1 W and standard operating range (0 °C to 70 °C), the module is hot‑pluggable and suitable for high‑density deployments. Rated to operate reliably in enterprise SAN environments, it supports backwards compatibility with 16 Gb and 8 Gb transfers, allowing smooth migration strategies or mixed-speed environments. The LC duplex interface and compact SFP+ form factor support flexible installation across HPE SN-series switches and server FC portsEngineered for mission-critical Fibre Channel environments, the P9H32A delivers dependable 32 Gbps throughput with minimal latency. Its VCSEL laser design provides signal stability over multimode fiber, ensuring reliable transmission in SAN fabrics even under heavy workloads. Integrated diagnostics (DDM/DOM) enable real-time visibility into optical signal parameters, helping IT teams monitor signal degradation or environmental anomalies before impacting performance
