Due to the ever-increasing bandwidth demand of hyperscale data centers, the transition to 400G Ethernet is now in full swing and the industry is already planning for the next phase of 800G. QSFP-DD800 is one of the leading multi-source agreements to drive the development of 800G interconnectivity and MultiLane provides a QSFP-DD800 development kit that includes a module compliance board, host compliance board and loopback module.
QSFP Double Density Passive Loopback Module ML4062-SLB-112, is used for testing QSFP Double Density transceiver ports under board level tests.
The ML4062-SLB-112 is packaged in a standard MSA housing compatible with all QSFP Double Density ports. Transmit data from the host is electrically routed, (internal to the loopback module), to the receive data outputs and back to the host. It provides an economical way to exercise QSFP Double Density ports during R&D validation, production testing, and field testing.
