Detailed Specifications
HPE QK725A - 16Gb SFP+ Long-Wave Transceiver 10 km
Overview :
The HPE QK725A is a pluggable SFP+ optical transceiver module designed for SAN and data-centre environments requiring Fibre Channel links up to 16 Gbps. It operates over single-mode fiber at a nominal wavelength of 1310 nm and supports distances up to 10 km, making it suitable for inter-rack or campus-link deployments. The module fits standard SFP+ slots and is compatible with HPE B-series switching/storage platforms, enabling straightforward upgrade paths in established infrastructures. The device also supports digital diagnostics (DOM) for real-time monitoring of optical parameters and runs in a commercial operating temperature range.
Key Features :
Supports up to 16 Gbps Fibre Channel data rate
Long-wave (1310 nm) single-mode fiber operation to 10 km
Duplex LC connector interface for industry-standard connectivity
Hot-pluggable SFP+ form factor for minimal downtime
Built-in DOM/diagnostics monitoring of optical parameters
