XT/Gb-E24 is a 24-Port Managed Carrier Ethernet Switch providing high density, high port count, Carrier Grade Ethernet switching capabilities in an extremely small embedded form factor. Excellent for any space constrained, mission-critical application needing an embedded high-density/high-port count managed Ethernet Switch.

The XT/GbE-24 implements on-board magnetics for all 24 ports, so no external magnetics are required for your end application. It has been designed from the ground up to ease enclosure/chassis integration by limiting the amount of cabling required for port termination with the ability to remove all cabling entirely.

The XT/GbE-24 uses specialized high density Board-to-Board/Board-to-Cable configuration for port breakouts. Ports can be broken out via a breakout board / carrier that can mate directly to the XDG024/25 or by mating to a high density high-speed Twinax cable.

There are 2 versions of the XT/GbE-24 i.e. XDG024 and XDG025.  While the XDG024 is meant for use with PCIe/104 stacks, the XDG025, a bus-less version of the XT/GbE-24, is designed for standalone applications, with all thermal extraction on one layer and connector/ cabling on the opposite layer.
