Cavo ottico attivo InfiniBand CBO QSFP-AOC-5M-CN-BO 5 m QSFP+ a QSFP+

The InfiniBand Active Optical Cable CBO QSFP-AOC-5M-CN-BO is a 5-metre QSFP+ to QSFP+ optical interconnect designed for short-reach, high-throughput links in data centre environments. With QSFP+ connectors on both ends, this active optical cable provides an optical alternative to copper for rack-to-rack and top-of-rack connections between switches, servers and storage. It is engineered to deliver low latency and immunity to electromagnetic interference while reducing power consumption compared with equivalent copper solutions.

Advantages

This active optical cable offers high data transfer performance with the stability expected in InfiniBand environments. Its optical medium eliminates EMI-related degradation and allows for consistent signal integrity over the 5 m span. The cable’s active components support low-latency operation and reduced power dissipation relative to copper direct-attach alternatives, making it suitable for dense rack deployments where thermal and electrical constraints matter.

Suitable for

• Rack-to-rack or top-of-rack connections in data centres
• High-performance computing clusters using InfiniBand
• Interconnects between switches, servers and storage appliances
• Environments requiring EMI immunity and stable low-latency links

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 5 metres
• Cable type: Active optical cable (AOC)
• Application: Short-reach InfiniBand interconnects
• Performance: Designed for low latency and high throughput
• Immunity: Resistant to electromagnetic interference (EMI)
• Power characteristics: Lower power consumption compared with copper direct-attach solutions

How to use

Install the QSFP+ connectors into compatible QSFP+ ports on switches, host adapters or storage devices. Ensure both devices support InfiniBand and the required link speed before insertion. Handle the cable by the connector housings and avoid bending the optical elements beyond recommended bend radii. After seating both connectors, verify link status in the device management interface and monitor for stable link negotiation and expected throughput.

Recommendations

Use in cooled rack environments and avoid running the cable alongside high-voltage power lines to maintain optimal signal integrity. For best results, pair the cable with hardware that explicitly supports QSFP+ active optical links and follow vendor guidance for firmware and transceiver compatibility.
