400G QSFP112 Loopback Module

QSFP112 400G, 4-channel parallel passive lookback module is for storages, servers, and switches QSFP112 port testing. The electrical loopback provides a cost effective method for QSFP112 port testing. Transmitting data from the host is electrically routed internally to the loopback module. The aggregate data rate of 400Gbps transmission can be achieved by this product.
