BlueOptics MCP7H60-W01AR30-BL cable de fibra óptica InfiniBand 2 m QSFP-DD 2xQSFP56

The BlueOptics MCP7H60-W01AR30-BL InfiniBand fibre optic cable is a 2 m high-density connectivity solution featuring a QSFP-DD plug on one end and two QSFP56 plugs on the other. Designed for short-reach interconnects in racks and adjacent rack rows, this cable supports high-speed data transmission with low latency and a male-to-male configuration that enables direct links between compatible switches, routers and storage systems. The product is suitable for environments that require compact 400G-class connections broken out to dual 200G channels for flexible port usage.

Advantages

This cable provides a compact breakout connection from a QSFP-DD port to two QSFP56 ports, enabling efficient use of high-density 400G interfaces while maintaining per-lane signal integrity and low power consumption. Manufactured to industry MSA guidelines and built from quality components, the cable is intended for reliable electrical transmission over a 2 m distance and is compatible with hardware platforms that support the corresponding 400GBase-CR8 / 2x200GBASE-CR4 electrical direct attach configuration. The passive twinax construction results in low latency, minimal maintenance and an extended expected service life for stable rack-level interconnects.

Suitable for

• High-density switch-to-switch or switch-to-router links within the same rack or adjacent racks
• Breakout of a 400G QSFP-DD port into two 200G QSFP56 ports for flexible port mapping
• Short-reach connections in data centers, server farms and storage arrays
• Environments requiring low-latency, low-power electrical direct attach cabling

Key specifications

• Cable length: 2 m
• Connector configuration: QSFP-DD (male) to 2 × QSFP56 (male)
• Transmission type: Passive direct attach twinax copper
• Supported data rates: up to 400 Gbit/s aggregate (2 × 200G channels)
• Wire gauge: 26 AWG
• MSA-compliant mechanical and electrical design
• Typical power consumption: low (passive cable, ~0.1 W typical environment impact)

How to use

Install the cable by firmly inserting the QSFP-DD connector into the 400G-capable source port and the two QSFP56 connectors into the corresponding destination ports. Ensure both endpoints officially support passive DAC breakout connections and the 400GBase-CR8 / 2x200GBASE-CR4 signaling protocol. Handle connectors by their housings, avoid excessive bending of the cable, and confirm link status through connected devices after installation. If the host hardware requires specific firmware or transceiver settings for passive twinax cables, apply those settings according to the device manufacturer's instructions.

Recommendations

Use this cable for short-distance electrical interconnects inside racks or between adjacent racks. Verify compatibility with the intended switch, router or storage platform before deployment and follow rack-cable management best practices to avoid tight bends and mechanical stress. For applications requiring longer reach or optical isolation, consider appropriate active or fibre optic alternatives.
