QSFP-DD CONNECTORS & CABLE ASSEMBLIES PRODUCT PORTFOLIO 400G PLUGGABLE I/O SOLUTIONS APPLICATIONS • SERVERS • SWITCHES • ROUTERS • DATA CENTERS • HIGH PERFORMANCE COMPUTING High Speed 400G Pluggable I/O Solutions 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. The QSFP-DD portfolio’s backwards compatibility allows existing QSFP modules to be plugged into QSFP-DD ports. Our QSFP-DD cages feature a proprietary heat sink design, making them the only solution to work in 15-18W applications at a low cost – providing superior thermal and signal integrity performance.
