A rugged 3U CompactPCI Serial Ethernet Interface board accommodates four fiber optic Ethernet transceiver channels (1000Base-SX) for high-speed connections over extended distances up to 1,800 feet (550 m). Connected to the backplane via a PCI Express x4 link and managed by a single IEEE 802.3x-compliant Ethernet controller, the G211F from Men Micro offers four channels to provide data transfers of up to 1,000 Mbit/s when used simultaneously. 

To enable highly flexible configuration, the board accommodates a wide range of small form factor package (SFP) transceivers that are quickly and easily inserted into the card cage, which hosts the optical adapter. Each interface features LEDs to indicate link status and activity. 

The G211F supports both full and half duplex operation depending on the choice of transceiver, such as an LC-duplex available from Men Micro, covering a broad range of rugged, embedded applications requiring high-bandwidth capacities as found in transportation, avionics and mobile medical equipment. As an alternative to the four channels, the board can be configured with two redundant channel pairs for safety-critical applications. The G211F peripheral board can be used in both pure CompactPCI Serial systems as well as in hybrid systems that utilize CompactPCI PlusIO boards. The single-slot G211F extends the number of Ethernet interfaces on the system slot CPU.

Screened operating temperature is -40° to +85°C excluding the transceivers. With a heat sink, the board weighs less than a half pound. It can withstand shock up to 50 m/s2(30 ms) and vibration up to 1.9 m/s2(5 Hz to 150 Hz) during operation in a maximum of 95% non-condensing humidity. At 40°C, MTBF is 311,742 hours according to IEC/TR 62380 (RDF 2000). Pricing starts at $644.
