About the PAN-QSFP-40G-LR4

The Palo Alto PAN-QSFP-40G-LR4 optical transceiver delivers long-reach 40 Gigabit Ethernet connectivity for data center campus interconnects and building core aggregation links. It integrates four CWDM optical wavelength channels across 1271, 1291, 1311, and 1331 nanometers over standard duplex single mode fibre up to 10 kilometers.

Compatibility

Compatible with Palo Alto PA-3200 Series, PA-5200 Series, and PA-7000 Series firewalls. It operates natively in QSFP+ ports, delivering high throughput backbone links across enterprise networks without external multiplexing hardware or separate optical amplifiers in data center facilities.

How to identify a genuine unit

Enclosed in a full metal QSFP+ casing with a blue pull tab extraction handle denoting longwave single mode optical operation. The label specifies part designation PAN-QSFP-40G-LR4, Palo Alto Networks branding, serial number, and laser safety class 1 compliance.

Buying used

Inspect the duplex LC optical receptacle with a microscope to verify clean optical surfaces. Seat the module in a live switch port to verify that PAN-OS recognizes the transceiver, powers up all four internal CWDM laser lanes, and reports steady optical telemetry.

Works together

How the Palo Alto PAN-QSFP-40G-LR4 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.
