About the PAN-SFP28-25G-SR

The Palo Alto PAN-SFP28-25G-SR optical transceiver delivers 25 Gigabit Ethernet transmission for enterprise data center firewalls and high throughput cloud interconnects. Transmitting over 850 nanometer multimode optical fibre up to 100 meters on OM4, it provides 2.5 times the bandwidth of 10GbE links using the compact SFP form factor.

Compatibility

Compatible with Palo Alto PA-3400 Series, PA-5400 Series, and PA-7000 Series firewalls equipped with SFP28 interfaces. It operates under PAN-OS with automated transceiver identification and continuous digital diagnostic telemetry reporting across data center networks.

How to identify a genuine unit

Enclosed in an SFP28 metal casing featuring an orange or black extraction latch bail indicating short-reach multimode optics. The manufacturer label identifies the component as PAN-SFP28-25G-SR with Palo Alto Networks branding, individual serial number barcode, and laser safety warnings.

Buying used

Inspect the optical bore with a fiber microscope to verify clean optical surfaces. Test the module in a 25GbE firewall port with FEC enabled to confirm error-free packet reception, stable optical link synchronization, and proper digital optical monitoring telemetry.

Works together

How the Palo Alto PAN-SFP28-25G-SR connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Storage

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
