Ascent OSFP-800G-ACC is a 800Gb/s twin-port OSFP (Octal Small Formfactor Pluggable)-to-2x400Gb/s twin-port OSFP Active Copper Cable (ACC) for InfiniBand NDR networking. ACC cables are the low-cost, low-latency, low-power consuming, high-speed links available due to their simplicity of design and minimal components. The “active” reference term in this cable refers to the passive copper cable with an equalizer integrated circuit to extend the length to 3, 4, and 5 meters while maintaining low-latency and low-power at 1.5 Watts per end. Thin 30AWG is used for 4m lengths and thicker 25AWG for 5m. Each end includes an EEPROM which provides product identification and characteristics to the host system. Every cable length is tuned to reduce signal noise and back reflections. The ACC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. Ascent’s cable 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.
