QSFP+ Loopback

QSFP+ series passive electrical Loopback module is used for high speed testing application for QSFP+ host ports. The module is designed for 40 Gigabit Ethernet applications and provides 4 RX and 4 TX lanes, I2C module management interface and all the QSFP+ SFF hardware signals. The module loops back 4-lane transmit data from the Host back to 4-lane receive data port to the Host, it provides an efficient way to verify QSFP+ ports during R&D test, manufacturing testing and field testing.
