Extreme Engineering Solutions (X-ES) introduced the XPort3300 XMC Module. The conduction- or air-cooled XPort3300 features dual 10 Gigabit and x8 PCI Express 2.0 port. Front panel I/O for the 10 Gigabit Ethernet interfaces can be provided with either dual optical SFP+ fiber optic connectors or a single RJ-45 10GBASE-T connector. The XPort3300 also supports rear 10GBASE-T I/O through the P16 connector, and utilizes X12d I/O mapping per VITA 46.9. The XPort3300 supports automatic negotiation down to 1000BASE-T if the 10GBASE-T port is connected to a Gigabit Ethernet device.
