800G OSFP DAC
The cables in this range come in lengths from 0.5m to 3m, 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.
Direct cables link two ports one-to-one; breakout versions fan one high-rate port out to several lower-rate ends, where the switch port supports breakout mode. All models in this range are passive: no power draw and nothing to configure.
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.
