French Liquid-Cooled Switch QSFP-DD

Home / French Liquid-Cooled Switch QSFP-DD

The QSFP-DD Series offers up to 400Gbps transmission speeds and features 1-by cages. QSFP-DD is a new module and cage/connector system similar to current QSFP, but with an additional row of contacts providing for an eight lane electrical interface. Electronics, optics, and copper wires are housed in metal shell plugs called form-factor plugs. Plugs have a cage counterpart that is in the network switch front panels and on top of network adapters. TE Connectivity's (TE) QSFP-DD (quad small form-factor pluggable double density) doubles the density of QSFP interconnects with an eight-lane electrical interface capable of 28 Gbps NRZ or 56 Gbps PAM-4 to achieve 200 or 400 Gbps aggregate per port. She discovered that her 800G QSFP-DD modules, which she had just purchased, experienced thermal throttling because she had not anticipated this problem.
