## Summary description

BlueOptics QSFP56 direct attach copper cable for 200GBASE-CR4 Ethernet, 30AWG conductor, 0.5 meter length. Designed for short-reach, high-speed server-to-switch or switch-to-switch connections supporting 200 Gbit/s over a CR4 electrical interface. Suitable for data center top-of-rack and aggregation links where a passive copper DAC provides low-latency, cost-effective connectivity.

## Long description

BlueOptics QSFP56 200GBASE-CR4 Direct Attach Copper (DAC) cable, blue jacket, 0.5 m length, provides a short-reach electrical connection for 200 Gbit/s links using a CR4 interface. The cable uses 30AWG conductors and QSFP56 form-factor terminated plugs to connect high-speed ports on servers, top-of-rack switches, or aggregation switches. It is intended for environments where low latency, high throughput and a compact, passive connection are required for short interconnects inside racks or between adjacent racks in data centers.
Advantages
The cable delivers 200 Gbit/s aggregate bandwidth over a single QSFP56 CR4 connection with low latency and minimal protocol overhead. Its passive copper design reduces power consumption compared with active electrical or optical modules and eliminates the need for separate transceivers, simplifying inventory and lowering total cost of ownership. The 0.5 m length and flexible 30AWG construction allow tidy cable routing in dense rack environments while maintaining stable signal integrity for short-distance links.
Suitable for
 Short-reach server-to-switch connections inside a rack
 Switch-to-switch aggregation links in top-of-rack deployments
 High-density data center interconnects requiring 200G throughput
Key specifications
 Data rate: 200 Gbit/s over CR4 electrical interface
 Connector type: QSFP56 to QSFP56
 Conductor gauge: 30 AWG
 Length: 0.5 meters
 Cable type: Direct attach copper (passive DAC)
 Jacket color: Blue
How to use
Insert each QSFP56 connector into the corresponding QSFP56 port on the devices to be linked; ensure the latch engages to secure the connection. Use the cable for direct electrical 200G links between compatible QSFP56 ports configured for CR4 operation. Confirm port settings and link status in the device management interface after insertion. For removal, press the connector latch and pull the plug straight out to avoid damaging the port or cable.
Usage recommendations
Install the cable in clean rack environments and avoid sharp bends; respect the manufacturer's minimum bend radius to preserve signal integrity. Use passive DACs for short spans up to the specified length and verify compatibility with switch or server QSFP56 ports before deployment.
