According to industry benchmarks, OSFP modules must operate reliably within temperature ranges from -40°C to 85°C, depending on the class (e. Effective thermal design ensures that the module's case temperature stays within safe limits, even under full. In addition to the integrated heatsink (IHS) modules, the OSFP-XD specification will also define a low-profile module that will use a riding heatsink (OSFP-XD RHS). The OSFP-XD RHS solution is not intended to support copper cable applications and is not expected to achieve the same thermal. This article explains contemporary thermal strategies for OSFP modules — from fin geometry tuning to detachable heatsink covers — and maps measured performance to practical deployment steps. Airflow / wind-pressure safe zone for OSFP heat sinks — shows upper & lower impedance curves. OSFP was designed to initially support 400 Gbps (8 lanes x 50G per lane) optical data links. Compared to other form factors, such as QSFP, OSFP is. An Octal Small Formfactor Pluggable (OSFP) module is disclosed, comprising a front side and a back side opposite the front side, a substantially continuous top surface extending from a portion of the front side to a portion of the back side, a data connector disposed formed on the front side, and a. OSFP compatible techniques are discussed including the use of water cooling,addi tion of heat pipes, use of intercoolers, air-fins and air-foils, optimization of cooling fins, use of vapor chambers are discussed. In particular the invention relates to an as- sembly comprising an OSFP module. This specification defines the electrical connectors, electrical signals and power supplies, mechanical and thermal requirements of the OSFP-XD Module, connector and cage systems.
