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

CBO QSFP-AOC-5M-IX-BO is a 5-meter active optical InfiniBand cable with QSFP+ connectors on both ends. It provides direct optical connectivity for high-speed server, switch and storage interconnects without requiring separate transceiver modules. Designed for data center and high-performance computing environments, the cable delivers long-reach, low-latency links with reduced power consumption compared to equivalent copper solutions.

Advantages

The active optical design enables stable high-bandwidth transmission over a 5 m reach while keeping power consumption low and heat generation minimal. Native QSFP+ connectors simplify installation and remove the need to manage separate transceivers, reducing component count and potential points of failure. Optical signalling provides immunity to electromagnetic interference and supports low-latency links suitable for clustering, storage fabrics and switch interconnects.

Suitable for

• Server-to-switch and switch-to-switch interconnects in data centers
• High-performance computing clusters and inter-node links
• Storage area network connections and SAN fabric links
• Low-latency environments requiring fiber links with QSFP+ interfaces

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable length: 5 meters
• Transmission medium: active optical cable (AOC)
• Target interfaces: InfiniBand and compatible QSFP+ ports
• Performance: designed for multi-gigabit/40 Gbps-class links (QSFP+ bandwidth)
• Latency: low-latency optical signaling suitable for cluster and storage traffic
• EMI immunity: optical transmission reduces susceptibility to electromagnetic interference
• Power/thermal: lower electrical power and heat compared with equivalent copper cabling

How to use

Install the cable by inserting each QSFP+ connector into the corresponding port on network equipment until the latch engages. Ensure both connected devices support QSFP+ active optical links and are configured for the intended link speed and protocol (InfiniBand or compatible Ethernet/40 Gbps modes). Route the cable to prevent sharp bends and avoid mechanical strain on connectors; maintain the minimum bend radius recommended by the equipment vendor. No separate transceivers are required, but verify firmware and driver compatibility on connected devices for optimal operation.

Recommendations

For reliable operation, store and handle the cable by the connector housings, keep dust caps in place when connectors are not in use, and avoid exposure to direct tensile loads. When replacing or upgrading interconnects, confirm link negotiation settings on switches and hosts and test link status after installation to ensure stable throughput and expected latency characteristics.
