Network Cable Mellanox MCP1650-H02AE26 QSFP56 Direct Attach Cable 200GBASE-CR4 30AWG 3 Meter

The Mellanox MCP1650-H02AE26 QSFP56 Direct Attach Cable 200GBASE-CR4 30AWG 3 Meter is a passive copper interconnect designed for short-reach, high-bandwidth links. It provides a 200GBASE-CR4 electrical interface in a QSFP56 form factor and is intended for direct connections between compatible networking equipment in data centers and high-performance computing racks. The cable uses 30AWG conductors and measures 3 meters in length, offering a balance between signal integrity and flexible deployment within server rooms and equipment cabinets.

Advantages

This QSFP56 direct attach cable supports 200G data rates with a straightforward, low-latency copper link that does not require additional transceivers. Its 30AWG construction provides consistent electrical performance for short-reach applications while the 3 m length enables flexible placement of connected equipment. The connectorized QSFP56 ends simplify installation and reduce component count compared with separate transceiver-plus-fiber or transceiver-plus-copper solutions.

Suitable for

• Top-of-rack and end-of-row connections in data centers
• Direct links between switches, routers and network interface cards supporting QSFP56
• High-performance computing clusters requiring 200G interconnects
• Patch connections within equipment cabinets and short cable runs between adjacent racks

Key specifications

• Interface: QSFP56 direct attach copper (DAC)
• Data rate: 200GBASE-CR4
• Conductor size: 30AWG
• Length: 3 meters
• Cable type: Passive copper twinax

How to use

Install the QSFP56 direct attach cable by aligning each QSFP56 connector with the corresponding port on the networking devices and inserting until the connector latches. Ensure both ends are seated properly and that equipment firmware or port settings match the expected 200GBASE-CR4 operation. Route the cable to avoid sharp bends and excessive tension; maintain recommended bend radius for twinax copper to preserve signal integrity. If the link does not come up, verify port compatibility and check for proper seating and any administrative port settings that could disable the interface.

Usage recommendations

Use this 3 m QSFP56 DAC for short-reach, high-bandwidth connections where a passive copper solution is supported by both ports. Avoid extended exposure to mechanical stress, keep within manufacturer-specified bend radius, and confirm device compatibility with QSFP56 and 200GBASE-CR4 signaling before deployment.
