OSFP is a new pluggable form factor with eight high speed electrical lanes that will initially support 400 Gbps (8x50G). It is slightly wider and deeper than QSFP but it still supports 36 OSFP ports per 1U front panel, enabling 14.4 Tbps per 1U. OSFP has an integrated heat-sink that greatly improves thermal performance and enables modules with up to 15W power in a switch chassis with conventional airflow. 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. QSFP-DD operates up to 25G NRZ or 50G PAM4 modulation, providing solutions up to 200 Gbps or 400 Gbps aggregate. Like OSFP, QSFP-DD can also enable up to 14.4 Tbps aggregate bandwidth in a single switch slot. Unlike OSFP, QSFP-DD modules are backwards compatible to QSFP modules.
