Is the module on the OSFP side of the NIC OSFP-flat? Why is the OSFP-Riding Heatsink used?

Answered on 11:03 am
OSFP-flat and OSFP-Riding Heatsink are two types of OSFP modules that differ in their height and heat dissipation design.
OSFP-flat has a flat top and a height of 15.5 mm, while OSFP-Riding Heatsink has a riding heat sink on the top and a height of 18.5 mm.
Both types of OSFP modules can support up to 400 Gb/s or 800 Gb/s data rates, depending on the number of electrical lanes and the modulation scheme.
The choice of OSFP module type depends on the compatibility with the connector cage and the thermal performance requirements of the system.
For example, NVIDIA ConnectX-7 adapters use OSFP-Riding Heatsink modules because they have a riding heat sink on the connector cage, which can provide better cooling for the modules. However, some other systems may use OSFP-flat modules because they have a lower profile and can fit in more compact spaces.
