Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-2M-SW-BO 2m QSFP28 macho/macho

The BlueOptics Q28-AOC-2M-SW-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male is a short-reach active optical cable designed to provide high-bandwidth, low-latency connections between QSFP28 ports. At 2 meters in length, this cable supports high-speed data transmission suitable for data centre top-of-rack, server-to-switch and switch-to-switch interconnects where compact, reliable optical links are required. The QSFP28 male-to-male configuration enables direct connection between compatible networking equipment without additional transceivers.

Advantages

This 2m InfiniBand fibre optic cable delivers high throughput and low latency characteristic of QSFP28 interfaces while reducing electrical interference and heat compared with copper alternatives. Its active optical design allows for energy-efficient data transfer over short distances, and the standardized connector form factor ensures interoperability with equipment that supports QSFP28 ports. The compact cable length contributes to reduced cable clutter and improved airflow in rack environments.

Suitable for

• Data centre top-of-rack connections
• Server-to-switch links requiring QSFP28 ports
• Switch-to-switch stacking within short rack or aisle distances
• High-performance computing (HPC) clusters and InfiniBand fabrics

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 2 meters
• Interface: InfiniBand / QSFP28-compatible high-speed link
• Application: Short-reach, high-bandwidth interconnects

How to use

Install the cable by aligning each QSFP28 plug with the corresponding port on your devices and insert until the connector latches. Verify that the devices recognise the link and confirm link status via device management interfaces or LEDs. For hot-pluggable ports, connect or disconnect the cable while following your hardware vendor's safety and ESD procedures. Avoid bending the cable beyond the manufacturer’s recommended minimum bend radius to maintain optical performance.

Recommendations

For optimal performance, route the 2m fibre optic cable to minimise sharp bends and mechanical stress, maintain clear airflow in racks, and ensure QSFP28 ports are compatible and firmware is up to date. Use this cable for short, high-bandwidth links where active optical technology reduces heat and electrical noise compared with copper cabling.
