OSFP (Octal Small Form-factor Pluggable) is a pluggable optical module form factor standard designed for 400G, 800G, and future 1. Compared with QSFP-DD, OSFP allows taller module height, a larger top cooling area, and higher module power support. This article will explain the differences between the two designs to help users choose the appropriate product. Figure 1: Side View Comparison of OSFP-IHS vs OSFP-RHS What Is OSFP-IHS (Integrated Heat Sink)? OSFP-IHS is the standard and most widely deployed OSFP thermal solution. In this design, the heat. As a result, OSFP gradually developed two distinct thermal structures: IHS (Integrated Heat Sink) and RHS (Riding Heat Sink). This whitepaper highlights the key aspects and features of each solution with the expectation that both solutions will have a place in future data center applications. 6Tbps, helping data centers meet AI-driven capacity demands with minimal. EXTREMEPORT™ OSFP CONNECTOR AND CAGE SYSTEMS SUPPORTING 56G, 112G & 224G Amphenol's ExtremePort™ OSFP connector and cage family delivers a scalable, high-performance interconnect platform designed for next-generation data centers, high-density switch/router systems, and high-speed serial.
