Axiom Memory AXG98729 0.5 m 40G QSFP+ Passive DAC Cable

Create a short 40GbE connection between QSFP+ ports without using separate optical modules and a fiber patch cable. The Axiom Memory AXG98729 is a 0.5 m passive direct-attach cable specified for 40GBASE-CR4 links and Palo Alto equipment compatibility. Its short reach suits connections between equipment mounted side by side, stacked in the same rack, or positioned within close cable-management distance. 40GBASE-CR4 uses four 10 Gigabit lanes through a QSFP+ interface to provide a 40 Gigabit Ethernet link. Because this cable is passive, it does not add active signal-conditioning electronics to the assembly. Match both endpoints to compatible QSFP+ 40GbE interfaces and allow sufficient routing space so the cable is not placed under stress at either connector. The 0.5 m length distinguishes this cable from longer direct-attach options intended for cross-rack or extended in-rack runs. It minimizes excess cable where ports are adjacent while retaining the integrated, fixed-end QSFP+ cable format. The cable is identified with a TAA designation and cross-references Palo Alto PAN-QSFP-DAC-50CM compatibility for deployments requiring that interface-specific cable reference.
