BlueOptics Q28-AOC-15M-CP-BO InfiniBand fibre optic cable 15m QSFP28 Male/Male

The BlueOptics Q28-AOC-15M-CP-BO InfiniBand fibre optic cable 15m QSFP28 Male/Male is a 15-metre active optical cable designed for high-speed InfiniBand connections using QSFP28 interfaces. It supports reliable, low-latency data transmission between compatible network devices and compute nodes. The male-to-male QSFP28 connectors allow direct connection without transceivers, reducing interface complexity in rack and chassis installations.

Advantages

This fibre optic cable offers high bandwidth and signal integrity suitable for demanding computing environments. As an active optical cable, it provides lower power consumption and reduced electromagnetic interference compared with copper alternatives. The fixed 15 m length simplifies planning for medium-distance inter-rack and intra-row connections while maintaining consistent optical performance and error rates.

Suitable for

• Interconnecting InfiniBand switches and host channel adapters in data centers
• High-performance computing clusters and server-to-server links
• Storage networks and low-latency trading or scientific applications
• Rack-to-rack connections where QSFP28 interfaces are present

Key specifications

• Connector type: QSFP28 Male to QSFP28 Male
• Length: 15 metres
• Cable type: Active optical cable (AOC)
• Supported interface: InfiniBand over QSFP28 form factor
• Typical use: Short- to medium-range high-speed links
• Signal characteristics: Low-latency, high-bandwidth optical transmission

How to use

Ensure both devices have compatible QSFP28 ports and are powered down or in a safe state for hot-plugging according to the equipment manufacturer's guidance. Align and insert each QSFP28 connector into the host ports until it seats securely; latch mechanisms, if present, should engage. After connection, verify link status through device LEDs or management interfaces and confirm negotiated data rates. For removal, follow the reverse procedure, taking static precautions and supporting the cable to avoid stress on the connectors.

Recommendations

Route the cable to avoid sharp bends and areas of mechanical strain; maintain the manufacturer's minimum bend radius to preserve optical performance. Use appropriate cable management in racks to prevent tension on connectors. Operate in environments within the specified temperature and humidity ranges of connected devices and inspect connectors periodically for contamination or damage.
