Overview
Hot-pluggable electronics
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.
0°C to 70°C case temperature operating range
RoHS 5/6 Compliance
Applications
10 Gigabit Ethernet
Enterprise routers
Workgroup routers and switches
Servers
The XFP-CX4 is ideal for telecom central office and enterprise
data center applications. Whether extending bandwidth
in-system or inter-connecting between systems, the XFPCX4 transceiver offers an attractive combination of high
performance and low cost in an industry standard form factor.

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.

Reset; The falling edge initiates a complete reset of the module including the 2-wire
serial interface, equivqlent to a power cycle.
