BlueOptics Q28-AOC-1M-CP-BO InfiniBand fibre optic cable 1m QSFP28 Male/Male

The BlueOptics Q28-AOC-1M-CP-BO InfiniBand fibre optic cable 1m QSFP28 Male/Male is a 1-metre active optical cable engineered for high-speed short-range connections in data centre and high-performance computing environments. With QSFP28 connectors on both ends, it supports InfiniBand topologies and provides a compact, low-latency link suitable for connecting switches, servers and host adapters. The cable is intended to deliver consistent throughput and reduced signal degradation compared with longer copper alternatives.

Advantages

This InfiniBand fibre optic cable offers a compact 1 m length and QSFP28 male-to-male connectivity designed for high-density rack deployments. The active optical design reduces electrical interference and heat generation, helping maintain signal integrity at high transfer rates. Its plug-and-play form factor facilitates straightforward installation and replacement without the need for additional transceivers.

Suitable for

• Interconnects between QSFP28-enabled switches and routers
• Server-to-switch connections in data centres and HPC clusters
• Short-reach high-bandwidth links in storage and compute racks
• Low-latency links for InfiniBand fabrics

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 1 metre
• Application: InfiniBand high-speed data transmission
• Typical use: Short-reach interconnects in dense rack environments

How to use

Ensure both host ports support QSFP28 and InfiniBand signalling before installation. With equipment powered down or in maintenance mode, align each QSFP28 connector with the corresponding port and insert until the latch engages. After physical installation, power up the devices and verify link status through device indicators or management interfaces. No additional transceivers are required; if a link does not establish, check port compatibility, firmware settings and cable seating.

Recommendations

Position the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius recommended for optical cables. Use in temperature-controlled rack environments and avoid routing near strong electromagnetic sources. For best performance, match the cable length to rack layout to minimise excess slack and potential signal reflections.
