HP QW923A 16Gbps Fibre Channel SFP+ Transceiver 850nm

SKU CH-B50B-P0KDF

A 16 Gbps Fibre Channel SFP+ transceiver for 850 nm multi-mode fibre links

  • Device TypeTransceiver
  • 16 Gbps throughput for high-speed storage networks
  • 850 nm wavelength optimized for multi-mode fibre links
  • SFP+ form factor fits standard switch and HBA ports
  • HP QW923A part number ensures genuine compatibility
  • New bulk packaging ready for immediate deployment

HP QW923A 16Gbps Fibre Channel Transceiver

The HP QW923A is a 16Gbps Fibre Channel SFP+ transceiver operating at 850nm wavelength. It provides a high-speed optical link for multi-mode fibre networks in enterprise storage and server environments. The module is supplied new and supports the standard SFP+ form factor for hot-pluggable installation.

Suits 16Gbps Fibre Channel multi-mode links

This transceiver suits administrators extending or repairing 16Gbps Fibre Channel fabrics over multi-mode fibre. It is not for single-mode fibre runs, for lower-speed 8Gbps or 4Gbps links that require different optics, or for Ethernet SFP+ ports that use a different protocol. Buyers needing longer reach than multi-mode allows should look elsewhere.

Handles 16Gbps over multi-mode fibre

The module comfortably handles 16Gbps Fibre Channel traffic over standard multi-mode fibre distances. It runs out when the link length exceeds the reach supported by 850nm multi-mode optics or when the host equipment requires a different speed or fibre type. No other speeds or wavelengths are supported by this part.

Questions about this item

What SFP+ port speed must my switch or HBA support for the QW923A to operate at 16Gbps?

The transceiver requires a 16Gbps Fibre Channel SFP+ port; it will not negotiate down to lower Fibre Channel speeds.

Can the QW923A share a multi-mode fibre plant with legacy 8Gbps or 4Gbps transceivers?

Yes, the 850nm wavelength is common across those generations, but each link end must match the same Fibre Channel speed.

How do I confirm the QW923A is linked at 16Gbps after installation?

Check the switch or HBA port status for a 16Gbps Fibre Channel link light and verify zero CRC errors in the interface counters.
