This cable is a 2x 400Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) to 2x 400Gb/s twin-port OSFP active optical cable (AOC). It integrates eight high-speed electrical pairs, each supporting up to 100Gb/s with 100G-PAM4 modulation to deliver 800Gb/s links. It is compliant with OSFP MSA (Multi-Source Agreement), CMIS Rev 4.0, SFF-8679, and IEEE 802.3bs standards.
Both ends use a IHS/finned top design optimized for air-cooled switches. Boasting cost-effective deployment, high operational stability and superior value, this AOC is ideally suited for 800G connections within racks and across adjacent racks in cloud computing and high-performance computing (HPC) scenarios. It also supports configurations for 400G applications, providing flexibility for various network setups.
Note: "Finned top" transceivers are now called "Integrated Heat Sink" (IHS) as the cooling fins are integrated into the OSFP connector metal top. Commonly used in air-cooled switches.
"Flat top" transceivers are now called "Riding Heat Sink" (RHS) as the cooling fins ride on top of the network card or system's internal cages. This is used for both air-cooled and liquid-cooled applications for DGX, ConnectX-7, and BlueField-3 DPUS.
