800G OSFP to 4x200G QSFP112 Breakout DAC
The cables in this range come in lengths from 0.5m to 2m, in passive copper builds. A DAC is the simplest short link there is: two transceiver ends on one twinax copper cable, no optics and almost no power draw. Wire gauges and lengths for every model are in the table below.
These breakout DACs fan one high-rate switch port out to several lower-rate ends, for connecting a row of servers or lower-rate switches to a single uplink port. The switch port must support breakout mode; lengths are fixed, so pick by the longest leg you need to reach.
Every cable in this range is coded for major networking platforms and 100% tested before shipment, and is covered by a 3-year warranty with lifetime maintenance. Standard lead time is 3–7 days for most products, and samples are available for evaluation.
