Fujitsu Releases X2 Copper Transceiver Module for 10Gbit-CX4 Ethernet Applications

Fujitsu Components Asia, Limited, today announced the release of a copper electrical transceiver module compliant with the X2 multi-source agreement (MSA) specification Rev. 1.0b. The X2 x-mGC module transmits 10Gb/s Ethernet over 20m of standard InfiniBand copper cable (AWG24) or VSR parallel optics through a single port, offering a cost-effective, standards-compliant product targeted for multiple applications in 10Gb/s enterprise, storage, and telecom markets. Using the imbedded media detect circuit, transmission up to 300 meters over standard multi-mode can also be achieved using Fujitsu’s o-MGC optical media converter.

Half the size of a XENPAK module, the hot-pluggable X2 x-mGC module reduces occupied board space on line cards. Fujitsu is offering it in low-pak, mid-pak and hi-pak form factors as defined in the X2 MSA. First offering will be the mid-pak form factor, followed by the low-pak for PCI applications

The X2 x-mGC features an integrated control interface (MDIO) and includes CX4 transmitter and receiver ports. The MUX/DEMUX, XAUI interface and MDIO management functions are all integrated into the module, as is a precision oscillator that eliminates the need for an external reference clock. The host may control the X2 registers using the XAUI interface as defined in the X2 MSA.

The X2 module supports Link Alarm Status Interrupt. Total power consumption is less than 3.0 watts, and impedance is 100 ohms differential, AC-coupled I/O.
