10GBASE-CX4 Copper XFP Transceiver XFP-CX4 Overview The XFP-CX4 copper transceiver from MRV Communications provides cost-effective and reliable bandwidth transport of up to 12.5 Gigabits over distances of up to 15 meters. The product provides 4 full-duplex, 3.125 Gigabaud transmit and receive channels over a single parallel copper cable that is transparent to the user. It not only offers the ability to scale net bandwidth in 10 Gigabit increments, it also mates directly with the industry standard MDI electrical socket. The XFP-CX4 is ideal for telecom central offi ce and enterprise data center applications. Whether extending bandwidth in-system or inter-connecting between systems, the XFP- CX4 transceiver offers an attractive combination of high performance and low cost in an industry standard form factor.

Connect these pins to the host system’s circuit common ground plane. Vcc Power supply provides +3.3 VDC when an active module (QTR3400) is plugged into the socket. Output is AC ground when a regular copper cable is present. TX0+ through TX3+ CML compatible transmitter data out+ for channels 0 through 3, respectively. TX0- through TX3- CML compatible transmitter data out- for channels 0 through 3, respectively. RX0+ through RX3+ CML compatible transmitter data in+ for channels 0 through 3, respectively. RX0- through RX3- CML compatible transmitter data in- for channels 0 through 3, respectively. ODIS Used to control the active module. Grounded in this CX4 implementation. Type_Sense Used to determine whether or not active module is present. It is an AC ground. Fault- Transmitter Fault signal or Loss signal from receiver side. Grounded in this CX4 implementation. Note: The cable side pin assignment is compatible with the Fibre Channel standard proposal (PI-2) that supports active modules. When a copper cable is plugged in, then all G_signals are ground.
