    50G DAC Direct Attach Copper Cable Overview

    C-LIGHT 50G DAC direct attach copper cables are designed for short-distance 50Gbps connections between servers, switches, network adapters, and other high-speed data center equipment. By integrating the copper conductors and connector assemblies into a single cable, the solution provides a simple and efficient alternative to optical interconnects for short-reach applications.

    The 50G DAC family is built around SFP56 and QSFP56 interfaces, supporting both direct 50G connections and breakout architectures. These configurations allow the cable to be used in different network topologies, including connections between 50G ports and multiple lower-speed interfaces.

    With short cable lengths and direct electrical transmission, 50G DAC is particularly suitable for rack-level connections where low latency, compact cabling, and power efficiency are important. It can also support network upgrades from 25G toward higher-speed 50G infrastructure.
