HP 16Gb SFP+ Transceiver

The HP QW923A is a 16Gbps SFP+ transceiver module built for Fibre Channel storage networks. It connects switches and host bus adapters over multi-mode fibre in enterprise data centres. The module delivers short-range optical connectivity for high-speed block storage traffic. It targets infrastructure engineers who need reliable 16-gigabit links.

850nm wavelength for 100m reach

This transceiver operates at an 850nm wavelength and supports a maximum link distance of 100 metres on OM3 or OM4 multi-mode fibre. The 16Gbps transfer rate matches 16G Fibre Channel specifications. Selecting this part requires confirmation that the host equipment supports 16Gbps SFP+ optics at 850nm. Mismatched speed or wavelength will prevent the link from coming up.

Hot-plug SFP+ installation

The SFP+ form factor allows hot-plug insertion into compatible switch or HBA ports without powering down the chassis. Align the module, slide it firmly until the latch clicks, then connect pre-terminated LC duplex patch cords. Common issues include inserting the module upside down, using single-mode fibre by mistake, or exceeding the 100m distance budget on lower-grade cable.

Questions about this item

How far will the 16 Gbps link reach over multimode fibre at 850 nm?

The module is rated for 100 m on multimode fibre at 850 nm when running at 16 Gbps.

Does the SFP+ form factor limit the 16 Gbps throughput in any way?

The SFP+ cage carries the 16 Gbps electrical interface; the module itself sets the 100 m optical reach.

Will this transceiver fit a standard SFP+ cage without extra brackets?

Yes, it uses the industry-standard SFP+ footprint and latches directly into any compliant cage.
