200G QSFP56 DAC cables are high speed, cost-effective alternatives to fiber optical transceivers in 200G Ethernet and 200Gb/s InfiniBand HDR applications. The QSFP56 direct-attach passive copper cable contains eight high-speed copper pairs, each operating at data rates of up to 50Gb/s with PAM4 modulation.

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.
