800Gb/s Twin-port OSFP to 4x 200Gb/s QSFP112 Active Copper Splitter Cable,5 Meter

AscentOptics TO4Q12-800G-ACxM is an 800Gb/s twin-port OSFP (Octal Small Formfactor Pluggable) to 4x200Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Active Copper Cable (ACC) quad breakout (aka splitter) cable for InfiniBand NDR networking. The switch end OSFP has a finned top for additional cooling and the QSFP112 HCA end is flat topped and uses riding heat sinks on the HCA OSFP cage. The ACC contains eight high-speed electrical copper pairs, each operating at data rates of up to 100Gb/s using 100G-PAM4 modulation. 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 very low-latency and very low-power at 1.5 Watts and 0.6 Watts per split end. Thin 30AWG is used for 4m lengths and thicker 26AWG for 5m. Each end includes an EEPROM which provides product identification and characteristics to the host system. For lengths less than 4-meters, use passive DAC cables. Main use is to link an 800Gb/s Quantum-2 switch to QSFP112-based 200Gb/s BlueField-3 DPUs (Datacenter Processing Units) or to 200Gb/s ConnectX-7 HCAs (Host Channel Adapters) at medium lengths of 4 and 5-meters. Both DPUs and HCAs can be used at the same time. AscentOptics’ 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.
