200G DAC Cable is an important stage in the evolution of high-speed interconnect technology in data centers, typically serving as a key transition or economical solution for upgrading from 100G networks to 400G/800G networks.
C-LIGHT 200G DAC direct attach copper cables are designed for short-distance 200Gbps connections in computer data centers, cloud server environments, and high-performance networking systems. The integrated copper cable assembly provides a direct electrical connection between compatible network ports without requiring separate optical transceivers and fiber patch cords.
The 200G DAC product family supports QSFP56 and QSFP-DD platforms, providing both direct 200G connections and breakout configurations for connecting higher-speed ports with lower-speed network interfaces.
With cable lengths from 0.5m to 3m and 28AWG copper construction, the 200G DAC series is well suited to rack-level and nearby equipment interconnection. The portfolio includes commercial and industrial temperature options for different deployment environments.
C-LIGHT positions 200G DAC as an economical and practical stage in the evolution of high-speed data center interconnects, particularly for network environments transitioning from 100G toward higher-speed 400G and 800G architectures.
The 200G DAC provides high-bandwidth connectivity for modern data center and cloud networking applications.
QSFP56 configurations provide a native 200G connection option for compatible servers, adapters, and switching equipment.
QSFP-DD versions extend the 200G DAC portfolio to equipment using the widely adopted QSFP-DD form factor.
The supported cable length range covers common short-distance connections within racks and between nearby network devices.
The listed 200G configurations use 28AWG copper cable for high-speed short-reach electrical connectivity.
Selected configurations connect one 200G interface with two 100G interfaces for mixed-speed network deployment.
The QSFP56-based breakout option allows a 200G port to connect with four 50G SFP56 interfaces.
The product table lists both commercial and industrial temperature options for different equipment deployment conditions.
200G DAC provides short-reach connectivity between servers, switches, and network adapters in high-density cloud data center environments.
QSFP56 200G DAC is well suited to HDR InfiniBand environments requiring high-speed connections between compute systems and network infrastructure.
200G DAC can be used for short connections between AI servers and compatible switching platforms where high bandwidth and low-latency electrical connectivity are required.
The direct copper architecture provides a straightforward way to connect 200G server interfaces with compatible switches.
Short DAC assemblies can connect adjacent high-speed switches when the physical distance remains within the supported cable range.
200G DAC can serve as an intermediate connectivity solution for data centers moving beyond 100G toward 400G and 800G network architectures.
Breakout configurations allow 200G ports to connect with 100G or 50G interfaces, helping integrate equipment operating at different speeds.
The 0.5m to 3m cable range makes the product suitable for equipment installed within the same rack or in closely positioned racks.
The product provides a dedicated 200G interconnect option for network environments that require more capacity than 100G without immediately moving every connection to 400G or 800G.
With lengths from 0.5m to 3m, the 200G DAC portfolio is designed around common short-distance data center interconnection requirements.
The direct copper architecture provides a simple electrical transmission path for latency-sensitive server and switching connections.
200G-to-100G and 200G-to-50G options provide additional flexibility when connecting equipment with different port speeds.
Support for multiple form factors allows the cable family to address different generations and designs of high-speed network equipment.
C-LIGHT states that its 200G DAC high-speed cables are compatible with more than 100 brands of switches.
C-LIGHT states that its products undergo initial testing, final testing, and factory inspection as part of its quality control process.
C-LIGHT provides spot supply, customization services, technical guidance, long-term maintenance, and after-sales support for customer deployments.
