Cabo InfiniBand BlueOptics MCP1600-E02AE26 3 m QSFP28 macho-macho

The BlueOptics InfiniBand Cable MCP1600-E02AE26 3m QSFP28 Male-Male is a 3-meter high-speed copper/active optical interconnect designed for InfiniBand and Ethernet fabrics that use QSFP28 ports. The cable features QSFP28 male connectors on both ends and is intended for short-reach connections inside racks and between adjacent rack units in data centers. It provides a straightforward point-to-point link for servers, switches and host adapters where low latency and high throughput are required.

Advantages

This BlueOptics QSFP28 cable supports high data rates typical for InfiniBand and 100/200/400 GbE environments while minimizing signal loss and latency. The fixed-length 3 m design reduces clutter and simplifies cable management in dense installations. A male-to-male QSFP28 configuration ensures direct compatibility with standard QSFP28 ports on switches, NICs and storage controllers. The cable is engineered for reliable electrical and optical performance across short connections commonly found in modern rack layouts.

Suitable for

• Direct server-to-switch connections within a rack
• Interconnects between adjacent rack units in data center rows
• High-throughput storage fabrics and compute clusters
• Low-latency networking for HPC and virtualization hosts

Key specifications

• Connector type: QSFP28 male — both ends
• Cable length: 3 meters
• Supported link types: InfiniBand and compatible Ethernet fabrics (QSFP28-compatible)
• Intended reach: short-reach/rack-level connections
• Application: high-speed data center interconnects, server and switch links

How to use

Verify that both endpoints have QSFP28 ports and that the host devices support the required InfiniBand or Ethernet link speeds. Insert each QSFP28 male connector firmly into the corresponding port until it seats; ensure retention latches (if present) engage. Avoid excessive bending near the connector ends and route the cable to minimize strain and airflow obstruction. When removing the cable, depress the connector latch and pull straight out to avoid damaging ports.

Recommendations

For optimal performance, use this 3 m QSFP28 cable for rack-level and adjacent-rack connections rather than long-span links. Maintain appropriate bend radius, keep connectors clean, and confirm firmware and driver compatibility on endpoints to ensure full link speed and stable operation.
