Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-3M-CO-BO 3 m QSFP28 macho/macho

The BlueOptics Q28-AOC-3M-CO-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed interconnects in data centres and networking environments. Equipped with QSFP28 male connectors on both ends, this cable supports high-bandwidth links and low-latency transmission suitable for InfiniBand and compatible fibre optic interfaces. Its 3 m length enables flexible rack-to-rack or within-rack connections while maintaining signal integrity over a short-reach optical link.

Advantages

The cable offers low power consumption and reduced electromagnetic interference compared with copper alternatives thanks to its optical design. QSFP28 connector compatibility ensures a compact, high-density connection standard for 100 gigabit-class links and similar high-throughput protocols. The fixed-length active optical design delivers consistent performance without the need for separate transceivers, simplifying installation and inventory management.

Suitable for

• Server-to-switch or switch-to-switch high-speed links within data centre racks
• High-performance computing clusters using InfiniBand or QSFP28-compatible ports
• Short-reach optical connections where low latency and high bandwidth are required

Key specifications

• Length: 3 metres
• Connector type: QSFP28 male to QSFP28 male
• Optical medium: active optical cable (AOC)
• Supported protocols: InfiniBand and QSFP28-compatible high-speed links
• Typical use case: short-reach, high-bandwidth interconnects

How to use

Identify QSFP28 ports on the devices you intend to connect and ensure both ends are aligned with the port keyed guides before insertion. Insert each QSFP28 connector gently until it locks into place; no additional modules are required. For removal, release the connector latch following the device manufacturer’s instructions and pull the cable straight out to avoid damaging the port. Verify link status lights on connected equipment to confirm successful negotiation and link establishment.

Recommendations

Use the cable within its specified bend radius and avoid sharp bends or kinks to preserve optical performance. Route the cable to minimise mechanical strain and keep it clear of heat sources. For reliable operation, maintain a clean environment around connector interfaces and follow equipment vendor guidelines for QSFP28 port handling and hot-plug procedures.
