Direct Attach Cable BlueOptics MCP1650-V001E30 200Gb QSFP56 to QSFP56 DAC

BlueOptics MCP1650-V001E30 is a 200Gb Direct Attach Cable (DAC) with QSFP56 connectors on both ends, engineered for short-reach, high-bandwidth links inside data centers and network racks. This passive QSFP56-to-QSFP56 cable supports 200 Gigabit Ethernet speeds and offers a compact, low-power physical connection between switches, routers and servers. The cable is intended for environments that require dense, high-throughput interconnects and minimal latency for aggregation, spine-leaf or top-of-rack deployments.

Advantages

The passive design eliminates the need for separate transceiver modules and reduces power consumption compared with active optical solutions. QSFP56 connectors on both ends provide standardized interoperability with equipment that supports QSFP56 ports. The cable offers low insertion loss and consistent signal integrity across short distances, enabling reliable 200Gb links with minimal configuration. Its fixed-cable format simplifies rack cabling and reduces the number of serviceable components.

Suitable for (tasks / use cases)

• High-density switch-to-switch interconnects in aggregation and core layers
• Spine-leaf architecture links within compute clusters
• Top-of-rack connections between switches and server or storage chassis
• Short-reach, low-latency links in hyperconverged and virtualization environments

Key specifications

• Nominal data rate: 200 Gigabit Ethernet
• Connector type: QSFP56 to QSFP56
• Cable type: Direct Attach Cable (passive)
• Application: short-reach data center interconnects
• Typical latency: minimal, suitable for low-latency deployments
• Form factor: fixed twin-ax copper cable with QSFP56 plugs

How to use

Install the BlueOptics QSFP56-to-QSFP56 DAC by inserting each QSFP56 connector into compatible QSFP56 ports on the networking devices until the connectors click into place. Ensure devices are powered down or follow hot-plug procedures recommended by the equipment vendor when inserting or removing DACs. Verify link status through the switch or server management interfaces and confirm correct 200Gb negotiation and port configuration. Route the cable to avoid sharp bends and mechanical stress on the connector ends.

Usage recommendations

Use this passive DAC for short-distance connections within the same rack or between adjacent racks where 200Gb bandwidth and low latency are required. Avoid extended runs beyond the manufacturer's supported length for reliable performance. Handle QSFP56 connectors by the connector body and follow standard ESD precautions when installing or removing the cable.
