Transceiver SFP+ HPE 16 GB Short Wave E7Y09A

The HPE 16GB SFP+ Short Wave Transceiver (E7Y09A) is a fibre-channel optical transceiver designed for 16 Gbit/s links. It supports a maximum data transfer rate of 16000 Mbit/s and operates at an 850 nm wavelength. The module is rated for extended temperature operation and serves as a direct replacement for HPE’s earlier 16GB SFP+ model (QW923A), providing improved diagnostics and lifecycle control for storage networking environments.

Advantages

This transceiver includes enhanced features not available in the prior HPE 16GB SFP+ (QW923A), such as optical and electrical loopback, pre-emphasis and a lifecycle counter. These capabilities improve fault isolation, allow signal conditioning adjustments, and enable tracking of module usage over time, aiding in maintenance and diagnostics of fibre channel data streams.

Suitable for

• 16 Gbit/s Fibre Channel SAN links
• High-speed server and switch interconnects using SFP+ ports
• Environments requiring extended temperature operation

Key specifications

• Manufacturer: HP Enterprise (HPE)
• Model / MPN: E7Y09A
• Form factor / Interface: SFP+
• Maximum data transfer rate: 16000 Mbit/s (16 Gbit/s)
• Wavelength: 850 nm
• Temperature range: extended temperature rated

How to use

Install the SFP+ transceiver into a compatible SFP+ port on a switch, server or storage array following the host equipment vendor’s installation instructions. Connect appropriate multimode fibre cabling terminated with matching connectors. Verify link status and, where supported, use the host management interface or transceiver diagnostics to view loopback, pre-emphasis settings and the lifecycle counter to confirm proper operation.

Recommendations

Use certified multimode fibre and ensure compatibility with the host device firmware. Monitor diagnostics provided by the enhanced features to schedule maintenance and replace modules before end-of-life is reached.
