Ascent’s OSFP to 4x200G breakout ACC is an 800Gb/s twin-port OSFP (Octal Small Form-factor Pluggable) to 2x400Gb/s OSFP passive Active Copper Cable (ACC) dual breakout cable. The ACC uses 8-channels of 100G-PAM4 modulation and has lengths of 4 and 5 meters. The 8-channel, twin-port, OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. The four 200G ends support 2-channels of 100G-PAM4 (400G) use a flat top OSFP using riding heat sinks on the connector cage. For use in liquid-cooled systems, a twin-port OSFP version is available with a flat top (designated -FLT in the part number). ACC cables are low-latency, low-power consuming, high-speed links next to passive DACs due to their simplicity of design and minimal components. The “active” term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters while maintaining low-latency and low-power at 1.5 Watts and 0.6 Watts. Each end includes an EEPROM which provides product identification and characteristics to the host system. Ascent solutions provide power-efficient connectivity enabling higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. Rigorous cable production testing ensures best out-of-the-box installation experience, performance, and durability.
