The 400G QSFP-DD Passive Loopback Testing Module is designed for testing QSFP-DD transceiver ports on host systems, line cards, and evaluation boards. It supports 1x400G, 2x200G, and 4x100G port testing modes for 400GBASE Ethernet and HDR InfiniBand hardware verification. It also provides programmable power dissipation for port thermal validation. Built to QSFP-DD MSA standards, it delivers a cost-effective alternative to a full-featured transceiver for port bring-up, validation, and troubleshooting.
Power consumption can be configured by FS before shipment, and users can also set it via registers. If you need to configure power consumption, please contact sales or note the specific power consumption when placing an order.
