Product Details

The Q28-LBP is a QSFP28 passive electrical loopback module which is a hot pluggable form factor designed for high speed testing application for QSFP host ports. It is designed for 100 Gigabit Ethernet applications and provides 4x28G RX and TX lanes, I2C module management interface and all the QSFP SFF hardware signals.

The Q28-LBP loops back 4-lane 28 Gb/s transmit data from the Host back to 4 lane 28 Gb/s receive data port to the Host. It provides programmable power dissipation up to 5.5 W allowing the module to emulate all the QSFP28 power classes.
