AOC (Active Optical Cable) and DAC (Direct Attach Copper) 400G cables provide high-speed connectivity for large-scale network infrastructures. AOC 400G cables utilize active optical fibers to transmit signals at speeds of up to 400 Gbps, offering low latency and longer transmission distances. DAC 400G cables use copper conductors for direct connection between equipment, providing high compatibility and ultra-low latency transmission. These cables are ideal for demanding deployments requiring high bandwidth and reliable performance.
