The ML4002 is a QSFP+ passive electrical loopback module which is a hot pluggable form factor designed for high speed testing application for QSFP+ host ports. The ML4002 is designed for 56 Gigabit Ethernet applications and provides 4x14G RX and TX lanes, I2C module management interface and all the QSFP+ SFF hardware signals.
The ML4002 loops back 4-lane 14 Gb/s transmit data from the Host back to 4-lane 14 Gb/s receive data port to the Host.
The ML4002 provides programmable power dissipation up to 3.5W allowing the module to emulate all the QSFP+ power classes. It also provides an insertion counter and a temperature sensor.
