200G QSFP56 AOC is a QSFP56 VCSEL (Vertical Cavity Surface-Emitting Laser) based active optical cable (AOC) designed for use in 200Gb/s Ethernet or InfiniBand HDR systems. The 200G QSFP56 AOC offers high-end port density and configurability, and a much longer reach than passive copper cables in the data centers. 200G QSFP56 AOC has a standard SFF-8665 compliant QSFP56 port on the electrical side towards the host system. It contains four channels multi-mode fibers (MMF) optic transceivers per end, each channel of transceivers operates data rates up to 50Gb/ with PAM4 modulated signals (4x 50G PAM4). Assembled with fixed length of fiber cable, the AOC is easy to install and replace. AscentOptics’s high quality 200G QSFP56 AOC (active optical 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.
