Ethernet Rear Transition Modules

Ensemble IO Mezzanine Series The Ensemble® IOM-200 (IO Mezzanine) XMC module and IOR-280 RTM from Mercury Computer Systems provide the industry’s leading 10 Gbps ethernet IO density. When two IOM-200s are configured with the IOR-280 rear transition module (RTM), up to eight channels of 10 Gbps Ethernet can be supported per 6 U open VPX slot.

Features

Up to eight 10GbE channels per 6U OpenVPX slot
Rear Transition Module available supports two IOM-200 XMCs
Includes high-performance user programmable FPGA
Mercury-provided Intel-based drivers supported under Linux

Benefits

Industry-leading Quad 10Gbps Ethernet IO density
Leverages open standards to ensure interoperability
Applications can be partitioned across FPGAs and CPU processors for maximum effectiveness
Simultaneous enables real-time IO and digital signal processing tasks
