200G QSFP56 Breakout AOC is a QSFP56 VCSEL-based (Vertical Cavity Surface-Emitting Laser), cost effective 200Gb/s to 2 x 100Gb/s active optical splitter cable (AOC) designed for use in 200Gb/s Ethernet and InfiniBand HDR (High Data Rate) systems. It is compliant with SFF-8665 for the QSFP56 MSA specifications. It provides connectivity between system units with a 200Gb/s QSFP56 connector on one side and two separate 100Gb/s QSFP56 connectors on the other side, such as a link between a switch and two servers. The cable connects the data signals of 4x50G PAM4 from one single QSFP56 end to two QSFP56 ends, each of which transmit 2x50G PAM4 signals. AscentOptics’ high quality active fiber cable solutions provide power-efficient connectivity for data center interconnects. They enable higher port bandwidth, density and configurability at a low cost, and reduced power requirement in the data centers, HPC (High-Performance Computing) and storage networks.
