XPort3305 | Conduction-Cooled XMC with Dual 10 Gigabit Ethernet Interfaces and Rugged Optical Connector

Aug. 31, 2017
The XPort3305 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. This is a vastly superior alternative, rather than attempting to use large, commercial SFP+ and optical modules for conduction-cooled, rugged, and extreme temperature environments. The XPort3305’s optical LC connectors can support the same optical cables as standard SFP+ modules (slightly modified).The optical transceiver on the XPort3305 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 synchronization.
