Direct Attach QSFP56 Cable BlueOptics 980-9I65U-00J00A-BL, 200GBASE-CR4, 30AWG, 2 m

BlueOptics Direct Attach QSFP56 Cable 200GBASE-CR4, 2 m is a copper twinax assembly designed for short-reach 200 Gb/s connections between QSFP56 ports. The 30AWG cable provides a fixed, low-latency link for direct server, switch or NIC interconnects in high-density network environments. This 2-m cable is suitable for use in data center top-of-rack and middle-of-row topologies where a compact, cost-effective 200G physical layer connection is required.

Advantages

The cable offers a direct attach solution that eliminates the need for separate transceivers, reducing hardware complexity and total cost of ownership. Its 30AWG twinax construction provides stable electrical performance for 200GBASE-CR4 signalling over the specified 2 m reach. The assembly’s form factor and blue jacket make it straightforward to identify and route within dense cabling environments, while its fixed QSFP56-to-QSFP56 connectivity maintains low latency and high throughput for short-reach links.

Suitable for

• Short-reach server-to-switch or switch-to-switch 200 Gb/s links
• Top-of-rack and middle-of-row data center interconnects
• High-density rack environments and patching panels
• Network interface card (NIC) direct connections in servers

Key specifications

• Interface: QSFP56 to QSFP56 copper direct attach
• Data rate: 200 Gb/s (200GBASE-CR4)
• Cable gauge: 30 AWG twinax
• Length: 2 meters
• Cable jacket color: blue
• Reach: short-reach, intended for up to the specified 2 m

How to use

Insert each QSFP56 connector into the corresponding QSFP56 port on the devices to be connected, ensuring the latch engages and the connector is fully seated. Route the cable to avoid sharp bends and excessive strain on the connectors; maintain minimum bend radius as recommended for 30AWG twinax cables. No additional configuration is required at the physical layer beyond verifying link status on connected devices and ensuring compatible port settings for 200G operation.

Usage recommendations

Use this 2 m direct attach QSFP56 cable for short, high-bandwidth links inside racks or between adjacent racks. Avoid running the cable in environments with high electromagnetic interference, and keep the cable clear of moving parts and hot airflow paths. Verify compatibility with device port firmware and link negotiation settings before deployment to ensure reliable 200G connectivity.
