HPE QK724A

16 Gb Fibre Channel Short-Wave SFP+ transceiver module – B‑Series, LC Duplex

The QK724A is a short-wave SFP+ transceiver moduledesigned for Fibre Channel SAN environments demanding high-throughput connectivity. Supporting 16 Gb/s Fibre Channel over multimode OM3 fiber, it enables link distances of up to 100 meters via duplex LC connectors. Engineered for use in HPE B-series SAN switches and director-class systems, this module suits data center, storage, backup, and virtualization deployments that require reliable, low-latency links.With full compliance to SFF-8431 and SFF-8472 standards, the QK724A delivers seamless integration and includes Digital Optical Monitoring (DOM) for real-time diagnostics. Hot-pluggable and compact, it plugs into any SFP+ port, making it ideal for scalable, flexible SAN architectures where uptime and consistency are critical.

Features

This plug-in transceiver operates over multimode fiber at 850 nm wavelength, achieving Fibre Channel data rates of up to 14.025 Gb/s (16GFC) and backward compatibility with 8G and 4G Fibre Channel speeds . It supports link distances up to 100 m on OM3 fiber, enabling efficient SAN connectivity without optical attenuation issues

Advanced Options

Internally, it includes a VCSEL transmitter and PIN photodiode receiver, built-in Clock Data Recovery (CDR), and DOM capabilities—which allow for live monitoring of optical power, temperature, and voltage Compliance with SFF-8431 and SFF-8472 ensures robust interoperability across certified SFP+ slots and Fibre Channel platforms.
