Conduction-Cooled XMC with Dual 10 Gigabit Ethernet Interfaces and Rugged Optical Connector

The XPort3305 from Extreme Engineering (X-ES) is a conduction-cooled dual 10 Gigabit Ethernet XMC with front and rear panel I/O support. A x8 PCI Express 2.0 port is routed per VITA 42.3 to the P15 connector for interfacing with the host module.

Front panel I/O for the 10 Gigabit Ethernet interfaces is provided with an integrated rugged 10GBASE-SR optical transceiver, which is positioned so that the optical cable can be run out of the front or bottom side of the module. This enables an optical 10 Gigabit Ethernet connection, even when front panel access to the module is not provided by the host module or the system, potentially preventing costly rework to the host card or chassis.

Backplane I/O for the 10 Gigabit Ethernet interface is supported with either XAUI, 10GBASE-BX4, or 10GBASE-KX4 protocols. The XPort3305 also supports IEEE 1588, and it supports the use of an externally sourced clock reference, such as a 1PPS, for synchronisation.
