Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-15M-IB-BO 15 m QSFP28

The BlueOptics Q28-AOC-15M-IB-BO InfiniBand fibre optic cable 15m QSFP28 is a 15-meter active optical cable with QSFP28 male connectors on both ends, designed for high-speed, low-latency connections in data centers and high-performance computing environments. This cable supports InfiniBand protocol transmission and is intended for direct attachment between QSFP28 ports on switches, servers and storage systems where reliable short-to-medium range optical links are required.

Advantages

This QSFP28 active optical cable offers high bandwidth and low latency suitable for InfiniBand networks, combining the signal integrity of fibre optics with the convenience of a fixed-length direct-attach solution. Its 15 m length provides flexibility for rack-to-rack or within-room connections while avoiding electrical signal degradation over longer copper links. The QSFP28 connectors ensure compatibility with standard QSFP28 ports and deliver consistent performance in dense networking deployments.

Suitable for

• Interconnecting switches and routers in data center topologies
• Connecting servers to storage arrays in HPC clusters
• Short- to medium-range optical links within server rooms and racks
• Low-latency InfiniBand fabrics and RDMA over Converged Ethernet environments

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 15 meters
• Media: active fibre optic (AOC)
• Supported protocol: InfiniBand
• Typical use: short- to medium-range high-speed links

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your network equipment until it seats securely. Ensure devices are powered down or that hot-swap procedures are followed according to the equipment manufacturer's guidelines if necessary. Verify link status and speed through the host or switch management interface and monitor for any error counters to confirm proper operation.

Recommendations

For best results, route the cable to avoid sharp bends and excessive stress on connectors, maintain appropriate bend radius for the AOC assembly, and ensure airflow within racks is not obstructed. Use this cable where optical active direct-attach solutions are preferable to copper for reduced latency and improved signal integrity over the given distance.
