Key Specifications for Palo Alto Networks Interfaces and Transceivers

The data interfaces implemented by Palo Alto Networks are based on industry standards and implementation agreements primarily authored by the Institute of Electrical and Electronics Engineers (IEEE) 802.3 committee and the Small Form Factor Committee (SFF). Each interface definition is supported by specifications and agreements defining the electromechanical coupling, electrical and optical signals, and management properties of compliant implementations.

Palo Alto Networks Next-Generation Firewalls utilize Ethernet interfaces in a mix of fixed form factor and pluggable formats, including 10 Mb/100 Mb/1 Gb tri-rate copper; 100 Mb/1 Gb/10 Gb tri-rate copper; 1 Gb SFP; 10 Gb SFP+; 40 Gb QSFP+; and 100 Gb QSFP28.

Fiber optic transceiver implementations are based on either multimode fiber (MMF) or single-mode fiber (SMF). It is critical to use a transceiver matched to the fiber deployed in the facility. Multimode transceivers must be used with MMF, and single-mode transceivers must be used with SMF. You can find educational material regarding fiber optics from multiple online sources, such as the Fiber Optic Association.

MMF is a low-cost, high-speed option for interconnections within a data center or building with distance limits measured in hundreds of meters. SMF supports distances measured in kilometers.
